                                                  Architecturally, Qwen3.5-Omni employs a Hybrid Attention Mixture-of-Experts (MoE)
                                                  framework for both Thinker and Talker, enabling efficient long-sequence inference. The
                                                  model facilitates sophisticated interaction, supporting over 10 hours of audio under-

                                                  and unnaturalness in streaming speech synthesis—often caused by encoding efficiency
                                                  discrepancies between text and speech tokenizers—we introduce ARIA (Adaptive Rate
                                                  Interleave Alignment). ARIA dynamically aligns text and speech units, significantly

                                                  emotional nuance. Beyond preset voices, the model enables zero-shot voice customiza-

                                                  emergence of a new capability in omnimodal models: directly performing coding based
                                                  on audio-visual instructions, which we call Audio-Visual Vibe Coding. Qwen3.5-Omni

                                         1    Introduction

                                         Human interaction with the world is inherently omnimodal and agentic, involving the integration of
                                         visual, auditory, and linguistic information, and the production of responses through text, speech, and
                                         goal-directed tool-mediated actions, facilitating information exchange with other organisms and demon-
                                         strating intelligence. Building on the rapid advances in the understanding and reasoning capabilities
                                         of large models across text (Brown et al., 2020; OpenAI, 2023; Gemini Team, 2024; Anthropic, 2023a;b;
                                         2024; Bai et al., 2023a; Yang et al., 2024a; 2025a; Touvron et al., 2023; Dubey et al., 2024), vision (Li
                                         et al., 2023; Liu et al., 2023; Zhu et al., 2023; Bai et al., 2023b; 2025a), and audio (Chu et al., 2023; 2024),
                                         natively omnimodal systems that jointly process and generate across all modalities have drawn sub-
                                         stantial attention (OpenAI, 2024; Comanici et al., 2025; Xu et al., 2025a;b). However, existing models
                                         predominantly operate within passive perception-response paradigms and exhibit limited capacity for
                                         scalable agentic behavior, real-time interaction, autonomous tool utilization, and cross-modal reasoning,
                                         which are essential prerequisites for practical deployment.
                                         In this report, we present Qwen3.5-Omni, Qwen’s latest generation of fully omnimodal LLM, supporting
                                         the understanding of text, images, audio, and audio-visual content. Natively pretrained in an omnimodal
                                         manner on massive amounts of text, visual data, and more than 100 million hours of audio-visual data,
                                         Qwen3.5-Omni is designed as a native omni agent model: it not only perceives and reasons across all
                                         modalities, but also acts, autonomously invoking WebSearch, executing complex FunctionCall, generating
                                         speech outputs, and engaging in real-time streaming interaction. The model series includes Plus and
                                         Flash variants, all of which are instruct models with 256k-token long-context input.
                                         Qwen3.5-Omni builds on the Thinker–Talker architecture introduced in Qwen2.5-Omni (Xu et al., 2025a)
                                         and introduces five key technical upgrades over Qwen3-Omni (Xu et al., 2025b): (1) both the Thinker

Figure 1: Qwen3.5-Omni is a unified end-to-end model capable of processing multiple modalities, such

features, Qwen3.5-Omni supports a wide range of tasks, including but not limited to voice dialogue,
video dialogue, and audio-visual tool use.


and Talker adopt Hybrid-Attention Mixture-of-Experts (MoE) designs, enabling highly efficient inference;
(2) supporting long-context modeling up to 256k tokens, supporting more than 10 hours of audio and
over 400 seconds of 720P audio-visual content at 1 FPS; (3) on the speech generation side, a multi-
codebook codec representation enables single-frame, immediate synthesis; (4) the Talker introduces
ARIA, a technique that dynamically aligns text and speech units during streaming decoding, significantly
improving naturalness and robustness; and (5) multilingual training is substantially expanded, covering
113 languages and dialects for speech recognition and 36 for speech synthesis.
Enabled by these technical advances, Qwen3.5-Omni delivers three major new capabilities over Qwen3-
Omni: (1) controllable audio-visual captioning, capable of generating controllable, detailed, and struc-
tured captions as well as screenplay-level fine-grained descriptions, including automatic segmentation,
timestamp annotation, and detailed descriptions of characters and their relationship to audio; (2) com-
prehensive real-time interaction, encompassing semantic interruption through native turn-taking intent
recognition, end-to-end voice control over volume, speed, and emotion, and voice cloning from user-
provided samples; and (3) native omnimodal agentic behavior, including autonomous WebSearch,
complex FunctionCall invocation, and Audio-Visual Vibe Coding, an emergent capability wherein the
model directly generates executable code from audio-visual instructions, enabling the model to respond
to real-time queries without external orchestration.
Critically, Qwen3.5-Omni maintains state-of-the-art performance on text and visual modalities without
degradation relative to same-size single-model Qwen counterparts. Across 215 audio and audio-visual
understanding, reasoning, and interaction subtasks and benchmarks, covering audio-visual benchmarks,
audio benchmarks, ASR benchmarks, language-specific speech-to-text translation tasks, and language-
specific ASR tasks, Qwen3.5-Omni-Plus achieves SOTA results, surpassing Gemini-3.1 Pro across general
audio understanding, reasoning, recognition, translation, and dialogue, while its overall audio-visual
understanding reaches the level of Gemini-3.1 Pro.

2     Architecture

2.1   Overview

As shown in Figure 2, Qwen3.5-Omni continues to adopt the Thinker-Talker architecture (Xu et al., 2025a).
Compared with Qwen3-Omni (Xu et al., 2025b), Qwen3.5-Omni introduces several key improvements in
scalability, alignment, and real-time interaction:


                                                   2
Figure 2: The overview of Qwen3.5-Omni. Qwen3.5-Omni adopts the Thinker-Talker architecture.
Thinker is tasked with text generation while Talker focuses on generating streaming speech tokens by
receives high-level representations directly from Thinker. To achieve ultra–low-latency streaming, Talker
autoregressively predicts a multi-codebook sequence. At each decoding step, an MTP module outputs the
residual codebooks for the current frame, after which the Code2Wav renderer incrementally synthesizes
the corresponding waveform, enabling frame-by-frame streaming generation.


     • The overall backbone adopts a Hybrid Mixture-of-Experts (MoE) design, improving scalability
       while better balancing capacity and efficiency across multimodal understanding and generation.
     • The Thinker receives visual and audio signals through the Vision Encoder and AuT, respectively.
       Audio and video inputs are interleaved for unified multimodal modeling, with explicit times-
       tamps inserted to improve temporal perception, especially for long video or audio-video contexts.
       This design enables the Thinker to handle extended inputs, supporting up to 256k tokens, 10
       hours of audio, or 400 seconds of 720P video at 1 FPS.
     • The Talker is responsible for contextual speech generation by conditioning on multimodal
       inputs together with the textual outputs from the Thinker. Qwen3.5-Omni adopts the RVQ-
       based speech representation introduced in Qwen3-Omni (Xu et al., 2025b), which substantially
       improves inference efficiency.
     • To support real-time interaction, Qwen3.5-Omni adopts both chunk-wise streaming input process-
       ing in the Thinker and a streaming Talker design, enabling low-latency end-to-end multimodal
       conversation.
     • Different from the dual-track Talker input design in Qwen3-Omni (Xu et al., 2025b), the Talker
       in Qwen3.5-Omni adopts ARIA to dynamically align text and speech units before interleaving
       them. This design mitigates the instability caused by mismatched tokenization rates between
       text and speech, thereby reducing issues such as skipped words, incorrect pronunciations, and
       ambiguous rendering of numbers.

In the following sections, we first introduce with the AuT encoder, including its training methodology.
Then, describe how Thinker processes various inputs. We then detail Talker’s multi-codebook streaming
speech generation. Finally, we highlight a series of improvements on both the understanding and
generation modules aimed at achieving ultra–low-latency, end-to-end streaming audio inference.

Figure 3: The overview of AuT. Consuming 40 million hours of supervised data especially more multi-
lingual data, AuT encoder in Qwen3.5-Omni obtain stronger general purpose audio representation in
6.25Hz.


2.2   Audio Transformer (AuT)

We use transformer based audio encoder trained from scratch in attention-encoder-decoder model AuT,
as is shown in Figure 3. The training of Qwen3.5-Omni encoder consumed 40 million hours of audio-text
pair data generated by Qwen3-ASR. The filter bank features of the audio are downsampled 16 times
using 4 Conv2D blocks and then fed into self-attention layers to obtain audio tokens in 6.25Hz token rate.
Comparing to the training process of Qwen3-Omni encoder, the encoder of Qwen3.5-Omni adapts more
multilingual data of more than 20 languages, and the proportion of Chinese, English and multilingual
data comes to 3.5 : 3.5 : 3. The dynamic attention window size training mechanism is adopted for
guaranting balance performance of inference under real-time prefill caching and for the offline audio
understanding tasks.

2.3   Perceivation

Text, Audio, Image and Video (w/o Audio). The Thinker converts text, audio, image, and silent video
inputs into a unified sequence of representations. For text, we use the Qwen3.5 tokenizer (Team, 2026),
which adopts byte-level byte-pair encoding with a vocabulary size of 250k (up from 150k), improving
encoding and decoding efficiency by 10–60% across most languages. For audio inputs, including audio
extracted from video, we resample the waveform to 16 kHz and convert it into a 128-channel mel-
spectrogram using a 25 ms window and a 10 ms hop size. We use AuT as the audio encoder, trained
from scratch on 40 million hours of audio data, where each output frame corresponds to approximately
160 ms of the original signal. For visual inputs, we adopt the vision encoder from Qwen3.5 (Team,
2026) to process both images and videos. Trained on a mixture of image and video data, this encoder
provides strong capabilities in both image understanding and video comprehension. To preserve video
information as much as possible while maintaining alignment with the audio stream, we sample video
frames at a dynamic frame rate.

Audio-visual Timestamp. Following Qwen3-Omni (Xu et al., 2025b), we apply TM-RoPE to endow
the model with temporal awareness for audio-video synchronization. However, we find that directly
encoding absolute time through temporal position IDs can lead to excessively sparse indices for visual
patches from long video with audio inputs, which weakens long-range temporal modeling. In addition,
such a design often requires large-scale and uniformly distributed training samples across different frame
rates, increasing data construction cost. To address these issues, we prepend each video or audio-video
temporal patch with an explicit timestamp represented as a formatted text string in seconds, allowing
the model to learn timecode representations more naturally. For audio sequences, we further insert
timestamps at random intervals to improve temporal alignment across modalities. Although this strategy


                                                    4
slightly increases the context length, it enables more precise and robust temporal perception, especially
when extrapolating long-context multimodal inputs.
In the context of multimodal audio-visual streams, the audio component is encoded with a temporal ID
for every 160 ms. The video is treated as a sequence of frames with monotonically increasing temporal
IDs that are dynamically adjusted based on their actual timestamps to ensure a consistent temporal
resolution of 160 ms per ID. The height and width IDs for video frames are assigned in the same manner
as for still images. To prevent positional conflicts when processing multiple modalities, the position
numbering is made contiguous, with each subsequent modality commencing from one plus the maximum
position ID of the preceding modality. This refined approach to positional encoding enables the model to
effectively integrate and jointly model information from diverse modalities. Qwen3.5-Omni aligns these
representations using their temporal IDs, which are explicitly anchored to absolute time. This design
choice affords the model the flexibility to support streaming inputs of arbitrary duration.

2.4   Speech Generation

Talker operates directly on the RVQ tokens produced by Qwen3.5-Omni-Audio-Tokenizer. To model the
residual codebooks, it employs a multi-token prediction (MTP) module, which enables fine-grained
modeling and control of acoustic details. Coupled with a causal ConvNet for waveform reconstruction,
Talker delivers high-fidelity speech synthesis with low inference latency and modest computational
overhead.
In multi-turn spoken dialogue, Talker is conditioned on the rich contextual information provided by the
Thinker component, including historical text tokens, multimodal representations, and the streamed text
of the current turn. Such conditioning allows Talker to dynamically modulate acoustic attributes—such
as prosody, loudness, and emotion—in accordance with the evolving conversational context.
Architecturally, our approach differs from Qwen3-Omni (Xu et al., 2025b) in two key respects. First, we
introduce a dedicated system prompt for Talker that specifies target voice characteristics, thereby enabling
both zero-shot voice cloning and controllable speech generation. Compared with conventional speaker
embeddings, this prompt can encode richer multimodal cues, including textual descriptions and codec
sequences, providing substantially finer-grained control over acoustic realization. Second, we propose
ARIA (Adaptive Rate Interleave Alignment), which unifies the conventional dual-channel generation
paradigm into a single-channel formulation. Rather than relying on MFA-derived alignments or fixed
interleaving rates, ARIA enforces an adaptive rate constraint: for any prefix of the generated sequence,
the cumulative speech-to-text token ratio must not exceed the corresponding item-level global ratio.
Despite its simplicity, this design affords flexible text-speech alignment across languages, including those
with relatively low encoding efficiency, and naturally supports arbitrary text-token prefixes followed by
coherent speech-token continuation.

2.5   Designs for Streaming and Concurrency

In streaming audio-visual interaction scenarios, the first-packet latency is a critical factor affecting user
experience, and the model’s concurrency capability is key to reducing service costs and improving
response speed. This section discusses how Qwen3.5-Omni enhances concurrency and reduces first-
packet latency through algorithmic and architectural optimizations. Table 1 provides an overview of the
relevant architecture of the Qwen3.5-Omni and its associated latency.

Chunked Prefilling and Hybrid MoE Architecture. In Qwen3.5-Omni, we retain the chunked-prefilling
mechanism as implemented in Qwen3-Omni and Qwen2.5-Omni, whose audio and vision encoders are


                                                     5
capable of outputting chunks along the temporal dimension. This approach significantly reduces the
Time-To-First-Token (TTFT) for both the Thinker and the Talker. Architecturally, both the Thinker and the
Talker in Qwen3.5-Omni are built upon the Hybrid MoE architecture introduced in Qwen3.5. Beyond
the general efficiency advantage of Hybrid MoE, this architecture includes the Gated Delta Net (GDN)
module, which is particularly effective for accelerating the modeling of long audio-video sequences. As a
result, it significantly reduces KV-cache I/O overhead in long-context inference, improving generation
throughput and enabling higher serving concurrency.

Streaming Generation with ARIA. For streaming speech generation and high-concurrency serving,
Qwen3.5-Omni largely inherits the efficient design of Qwen3-Omni: Talker predicts RVQ codec tokens
with a lightweight MTP module, and the generated multi-codebook tokens are converted to waveform by
a causal and streaming ConvNet codec decoder. These components remain computationally lightweight,
batch-friendly, and well-suited for low-latency deployment. Built on this shared foundation, the pre-
viously introduced ARIA further reformulates the dual-channel generation pattern in Qwen3-Omni
into a unified interleaved single-stream formulation over text and speech tokens. By organizing text
and speech generation under a monotonic interleaving constraint, ARIA reduces the synchronization
overhead between separate generation tracks, enables more efficient token scheduling during decoding,
and better matches the naturally incremental regime of streaming interaction.
In Table 2, we report the theoretical first-packet latency of Qwen3.5-Omni under different concurrency
levels for audio and video input, evaluated on internal vLLM with torch.compile and CUDA Graph
acceleration enabled for the MTP module and codec decoder. Here, Thinker TTFT (Time-To-First-Token)
denotes the time from receiving the input stream to the first text token generated by Thinker, while
Talker TTFC (Time-To-First-Chunk) measures the time until Talker produces the first audio chunk. TPOP
(Time-Per-Output-Token) represents the per-output-token latency during steady-state decoding, where
Talker TPOP includes the combined latency of the Talker backbone and the MTP module. TPS (Tokens Per
Second) denotes generation throughput. Since ARIA organizes text and speech generation in a unified
interleaved stream, Overall Latency cannot be obtained by simply summing several row values, but
instead reflects the end-to-end critical path to the first playable audio packet. We also note that, due to
the substantial scale difference between Qwen3.5-Omni-Flash and Qwen3.5-Omni-Plus, the two variants
adopt different deployment-time resource allocation and parallelization strategies; therefore, their latency
and throughput numbers are not intended for strict horizontal comparison. As shown in the table,
Qwen3.5-Omni maintains stable latency and decoding efficiency as concurrency increases, while the low
Generation RTF provides sufficient margin for smooth streaming audio generation.

3    Pretraining

Qwen3.5-Omni is pre-trained on a diverse dataset that encompasses multiple languages and dialects as
shown in Table 3 and modalities, including image-text, video-text, audio-text, video-audio, video-audio-
text, and pure text corpora. Following Qwen3-Omni (Xu et al., 2025b), we employ a wider range of natural
language prompts to enhance both the generalization ability and instruction-following capabilities. To
achieve robust performance across all modalities, our training strategy incorporates both unimodal and
cross-modal data from the early pretraining stage.
In Qwen3-Omni (Xu et al., 2025b), we employ TMRoPE to endow the model with temporal awareness.
However, we identify two key limitations of this approach: (1) By directly tying temporal position IDs to

absolute time, it produces excessively large and sparse temporal position IDs for long audio-video or
video inputs, which undermines the model’s ability to capture long-range temporal contexts. (2) Effective
learning under this scheme typically requires large-scale and uniformly distributed sampling across
different frame rates (fps), significantly increasing the cost of training data construction. To address
these issues, we prepend each video or audio-video temporal patch with a timestamp represented as a
formatted text string in seconds, enabling the model to better learn and interpret timecode representations.
In addition, for audio sequences, we insert timestamps at random intervals to better align training across
different modalities. Although this approach introduces a modest increase in context length, it allows the
model to perceive temporal information more effectively and precisely.
The pre-training of Qwen3.5-Omni is structured into three distinct stages. In the first stage, we lock
the LLM parameters and focus on training the vision and audio encoders, utilizing a vast corpus of
audio-text and image-text pairs to enhance semantic understanding within the LLM. In the second stage,
we unfreeze all parameters and train with a wider range of multimodal data for more comprehensive
learning with a sequence length of 32,768. In the final stage, we use data with a sequence length of
262,144 to enhance the model’s ability to understand complex long-sequence data:

    (1) Encoder Alignment Stage (S1): During the initial pretraining phase, the LLM component of
        Qwen3.5-Omni is initialized with parameters from Qwen3.5, while the vision encoder is adopted
        from Qwen3.5, and the audio encoder is initialized with AuT. The two encoders are trained
        separately on the fixed LLM, with both initially focusing on training their respective adapters
        before training the encoders.
    (2) General Stage (S2): The second phase of pretraining utilizes a large-scale dataset containing
        approximately 4 trillion tokens, with the following distribution across modalities: text (0.92
        trillion), audio (1.99 trillion), image (0.95 trillion), video (0.14 trillion), and video-audio 0.29
        trillion). During this stage, the introduction of more diverse multimodal data and tasks enhances
        the model’s understanding and interaction capabilities in auditory, visual, textual, and audio-
        visual information.
    (3) Long Context Stage (S3): In the final pre-training phase, we increased the maximum token length
        from 32,768 to 262,144 and also raised the proportion of long audio and long video in the training


                                                     7
         data. Experimental results indicate that these adjustments lead to significant improvements in
         the model’s ability to understand long sequence data.

4     Post-training
4.1   Thinker

The post-training phase employs a three-stage strategy for the Thinker, designed to preserve the model’s
capabilities across all modalities without degradation, ensure high response quality under audio queries,
and optimize the overall interaction experience. The training corpus, structured in the ChatML (OpenAI,
2022) format, encompasses pure text, visual, audio, and mixed-modality conversational data. Specifically,
the process consists of the following stages:

       • Stage 1: Specialist Distillation To establish a strong foundation for omnimodal capabilities, we
         first train a suite of domain-specialized teacher models via independent Supervised Fine-Tuning
         (SFT) and reinforcement learning (RL). All teacher models are fine-tuned from the pre-trained
         Qwen-3.5 base checkpoint. Beyond text-related tasks, including agentic, coding, and foundational
         reasoning tasks, we also train specialized teacher models for vision and audio. These teacher
         models are used to generate domain-specific data, enabling the specialized capabilities learned
         in each domain to be distilled into a single unified model.
       • Stage 2: On-Policy Distillation Through the specialist distillation described above, the model
         already achieves strong performance in domains such as multimodal understanding and rea-
         soning, as well as text-based dialogue, reasoning, coding, and agentic tasks. Nevertheless, a
         substantial gap remains between the quality of responses conditioned on audio queries and that
         of responses conditioned on text queries, particularly in speech dialogue. To reduce this gap, we
         introduce a second-stage training procedure based on on-policy distillation (OPD), with the goal
         of distilling the model’s stronger response capabilities under text inputs into the audio-input
         setting. Concretely, for each audio-text paired query, we first obtain a response generated un-
         der the text condition, which typically exhibits higher quality in terms of fluency, reasoning,
         and task completion. We then use this response as the distillation target for the corresponding
         audio-conditioned query. By training on such on-policy targets, the model gradually aligns
         its audio-conditioned outputs with its text-conditioned behavior, thereby improving response
         quality under audio inputs and promoting modality-consistent generation.
       • Stage 3: Interaction-Aligned Reinforcement Learning Although the previous two stages sub-
         stantially improve the model’s domain capabilities and cross-modal response quality, they are not
         sufficient to fully optimize the model for real-world interactive use. In multi-turn conversations,
         we observe several interaction-specific issues, including unintended language code-switching,
         persona inconsistency, and degraded instruction-following over extended contexts. To mitigate
         these issues, we introduce Interaction-Aligned RL, a third-stage reinforcement learning proce-
         dure aimed at optimizing the model for interaction quality. We construct multi-turn interaction
         trajectories and design reward signals around these user experience objectives, enabling the
         model to learn behaviors that are more stable, consistent, and aligned in prolonged interactions.
         By explicitly optimizing for interaction quality, this stage improves the model’s overall usability
         in practical conversational scenarios.

4.2   Talker

We employ a four-stage training pipeline for Talker, enabling Qwen3.5-Omni to generate natural and
contextually appropriate spoken responses jointly with text. All training data is organized in the ChatML
format to maintain consistency with Thinker and to facilitate voice cloning.

      (1) General Stage: In the initial pre-training stage, we train Qwen3.5-Omni on more than 20 million
          hours of multilingual speech data paired with multimodal context. In particular, the introduction
          of more diverse tasks, such as instruction-following speech generation, substantially enhance
          contextual reasoning and paralinguistic alignment, going beyond a simple monotonic mapping
          from multimodal representations to speech.
      (2) Long-Context Stage: We perform data quality stratification through a dedicated curation pipeline
          and conduct continual pre-training (CPT) on high-quality subsets. Augmented by Qwen3-Omni-
          Captioner, this stage mitigates hallucinations introduced by noisy data in the initial pre-training
          phase and substantially improves the naturalness and quality of generated speech. Meanwhile,
          we extend the maximum context length to 64k tokens, allowing the model to better handle long
          and complex user inputs and to produce more contextually grounded speech responses.


                                                      8
      (3) Reinforcement Learning Stage: We further align model behavior with human preferences
          through Direct Preference Optimization (DPO) (Rafailov et al., 2023). Concretely, we construct
          multilingual preference pairs based on human annotations and optimize the model with DPO.
          In addition, we incorporate rule-based rewards and adopt GSPO (Zheng et al., 2025) to further
          improve overall capability and training stability across diverse tasks.
      (4) Speaker Fine-tuning Stage: Finally, we perform lightweight speaker fine-tuning on top of the
          base model, enabling Qwen3.5-Omni to faithfully capture target speaker characteristics while
          further improving the naturalness, expressiveness, and controllability of its speech outputs.

5     Evaluation
A comprehensive evaluation was performed on two variants of models, including Qwen3.5-Omni-Flash
and Qwen3.5-Omni-Plus. The evaluation results are divided into two main categories: understand-
ing (X→Text) and speech generation (X→Speech).

5.1   Evaluation of X→Text

In this section, we evaluate Qwen3.5-Omni’s ability to comprehend various multimodal inputs (text,
audio, vision, and audio-visual video) and generate textual responses.

Text→Text Our evaluation of Qwen3.5-Omni on text → text primarily focuses on general knowledge
tasks, instruction following, long context tasks, STEM tasks, reasoning tasks and general agent ability.
Specifically, we utilize MMLU-Pro (Wang et al., 2024d), MMLU-Redux (Gema et al., 2024), SuperGPQA
(Team et al., 2025) and C-Eval (Huang et al., 2023) for general knowledge tasks, IFEval (Zhou et al., 2023)
and IFBench (Pyatkin et al., 2025) for instruction following, AA-LCR (Team, 2025a) and LongBench v2
(Bai et al., 2025b) for long context tasks, GPQA (Rein et al., 2023) for STEM tasks, LiveCodeBench v6
(Jain et al., 2024), HMMT Nov 25 (Balunović et al., 2025) and IMOAnswerBench (Luong et al., 2025) for
reasoning tasks, BFCL-V4 (Yan et al., 2024) and TAU2Bench (Barres et al., 2025) for general agent ability.

Audio→Text To evaluate audio-to-text capabilities, we employ benchmarks across four domains: audio
understanding, end-to-end speech dialogue, speech-to-text translation (S2TT), and automatic speech
recognition (ASR). For audio understanding, we utilize MMAU (Sakshi et al., 2024), MMAR (Ma et al.,
2025a), MMSU (Wang et al., 2025a), RUL-MuchoMusic (Zang et al., 2025), and SongFormBench (Hao et al.,
2025) to assess comprehension of sound effects, speech, and music. Dialogue performance is evaluated
via VoiceBench (Chen et al., 2024b), URO-Bench-pro (Yan et al., 2025), SpeechRole (Jiang et al., 2025), and
WildSpeech-Bench (Zhang et al., 2025b). For S2TT, we focus on the translation of the top 59 languages
in Fleurs (Conneau et al., 2022) into English and Chinese. Finally, ASR performance is measured using
Fleurs (Conneau et al., 2022), Common Voice (Ardila et al., 2020), LibriSpeech (Panayotov et al., 2015),
WenetSpeech (Zhang et al., 2022), KeSpeech (Tang et al., 2021), Opencpop-test (Wang et al., 2022), and
MIR-1K (vocal) (Hsu & Jang, 2010), covering multilingual speech, Chinese dialects, and singing voice
transcription.

Vision→Text The evaluation of the model’s vision-to-text capabilities encompasses a suite of bench-
marks targeting diverse and challenging tasks. To assess performance in specialized domain of mathemati-
cal and STEM reasoning, we utilize MMMU (Yue et al., 2023), MMMU-Pro (Yue et al., 2024), MathVista (Lu
et al., 2024), MathVision (Wang et al., 2024a), DynaMath (Zou et al., 2025), ZEROBench (Roberts et al.,
2025). For the general visual question answering, the model is evaluated on RealWorldQA (Zhang
et al., 2024), MMStar (Chen et al., 2024a), HallusionBench (Guan et al., 2024), and SimpleVQA (Cheng
et al., 2025). The model’s proficiency in document understanding is measured using the CharXiv (Wang
et al., 2024e), CC-OCR (Yang et al., 2024b), AI2D (Kembhavi et al., 2016), MMLongBench-Doc (Ma et al.,
2024), and OCRBench (Liu et al., 2024). Furthermore, the model’s spatial intelligence is specifically
tested on ERQA (Team, 2025b), CountBench (Paiss et al., 2023), RefCOCO (Kazemzadeh et al., 2014),
ODInW13 (Li et al., 2022), and EmbSpatialBench (Du et al., 2024a). To evaluate performance on dynamic
visual data, we report results on six video understanding benchmarks: Video-MME (Fu et al., 2024),
MLVU (Zhou et al., 2025a), MVBench (Li et al., 2024), LVBench (Wang et al., 2024b), MMVU (Zhao
et al., 2025) and MME-VideoOCR (Shi et al., 2025). Specifically, we evaluate the model’s performance on
medical VQA across three established benchmarks: SLAKE (Liu et al., 2021), PMC-VQA (Zhang et al.,
2023), and MedXpertQA-MM (Zuo et al., 2025). This assessment is designed to demonstrate the model’s
comprehensive clinical reasoning capabilities and its potential utility as a reliable healthcare AI assistant.

Audio-Visual Video→Text We evaluate our model’s audio-visual understanding capabilities from mul-
tiple perspectives. For text-query evaluation, we use DailyOmni (Zhou et al., 2025b), WorldSense (Hong


                                                      9
et al., 2025), AVUT (Yang et al., 2025b), AV-SpeakerBench (Nguyen et al., 2025), and VideoMME (Fu et al.,
2025). To assess the model’s ability in real-world audio-visual interactive scenarios, we use Qualcomm
IVD (Pourreza et al., 2025) as the benchmark for audio-query-based evaluation. Beyond understanding,
we also evaluate the model’s captioning capability on OmniCloze (Ma et al., 2025b) and its tool-use ability
on OmniGAIA (Li et al., 2026).

5.1.1    Performance of Text→Text
We compare Qwen3.5-Omni-Plus and Qwen3.5-Omni-Flash with Qwen3.5-Plus-Instruct. As shown in
Table 4, Qwen3.5-Omni-Plus demonstrates text capabilities that are on par with its text-only counterpart
across multiple dimensions, including knowledge, instruction following, long-context understanding,
STEM, reasoning, and general agent tasks, highlighting its strong language ability. In particular, Qwen3.5-
Omni ’s instruction-following performance is slightly better than the baseline. We believe that OPD and
interaction-aligned RL have a positive effect on improving the instruction-following capabilities of an
omni-model LLM.

5.2    Evaluation of X→Speech

In this section, we evaluate the speech generation capability of Qwen3.5-Omni. Our evaluation mainly
focuses on speech generation conditioned on text and prompt speech, following a zero-shot text-to-speech
(TTS) setting. We study the model from four perspectives:

       • Zero-Shot Speech Generation: We evaluate content consistency, measured by WER, on SEED (Anas-
         tassiou et al., 2024).
       • Multilingual Speech Generation: We evaluate both content consistency and speaker similarity
         in zero-shot multilingual speech generation on the TTS multilingual test set (Zhang et al., 2025a)
         and an internal multilingual test set built on FLEURS (Conneau et al., 2022).
       • Cross-Lingual Speech Generation: We evaluate content consistency in zero-shot cross-lingual
         speech generation on CV3-Eval (Du et al., 2025).
       • Custom-Voice Speech Generation: We evaluate the stability of our speaker fine-tuned model on
         the TTS multilingual test set (Zhang et al., 2025a) and our internal multilingual test set.

5.2.3   Evaluation of Cross-Lingual Speech Generation
Beyond multilingual voice cloning, Qwen3.5-Omni also supports cross-lingual voice cloning, where the
model is required to preserve speaker identity while generating speech in a different target language. We
evaluate this capability on the Cross-Lingual benchmark and compare against the CosyVoice series as
well as Qwen3-Omni-30B-A3B.
In Table 11, we report the mixed error rate (WER for English and CER for the other languages) across
different source–target language pairs. Overall, Qwen3.5-Omni achieves the best performance in 10 out
of 12 evaluated directions and sets a new state of the art on most English-, Japanese-, and Korean-targeted
pairs. In particular, for zh-to-ko, Qwen3.5-Omni reduces the error rate from 14.4 to 4.03 compared with

strongly on commonly used language pairs such as zh-to-en and en-to-zh, indicating better content
consistency under cross-lingual generation. These results demonstrate that Qwen3.5-Omni generalizes
effectively across language boundaries while preserving target linguistic accuracy.

As shown in Table 12, although Qwen3.5-Omni is fine-tuned only on monolingual data, it demonstrates
strong cross-lingual generalization in custom-voice speech generation. The model is able to transfer the
target speaker characteristics to all 29 evaluated languages while maintaining stable generation quality.
Overall, Qwen3.5-Omni achieves the best WER in 10 languages and remains competitive in many others.
In particular, it shows clear advantages in several challenging languages, including Japanese (3.306) and
Korean (1.309), indicating strong intelligibility under cross-lingual voice transfer. These results suggest
that Qwen3.5-Omni can generate custom-voice speech with robust linguistic fidelity across a wide range
of languages.

6   Conclusion

In this work, we present Qwen3.5-Omni, a fully omnimodal large language model that unifies under-
standing, reasoning, generation, and action across text, images, audio, and audio-visual inputs. Built
on the Thinker–Talker framework, Qwen3.5-Omni introduces efficient Hybrid-Attention MoE architec-
tures, 256k long-context modeling, improved streaming speech generation with multi-codebook codec
prediction and ARIA, and substantially expanded multilingual speech support. These advances enable
three key capabilities: controllable audio-visual captioning, comprehensive real-time interaction, and
native omnimodal agentic behavior through autonomous tool use and audio-visual code generation.
Empirically, Qwen3.5-Omni achieves state-of-the-art or highly competitive performance across a broad
range of audio and audio-visual benchmarks, while maintaining the strong text and vision capabilities
of same-scale Qwen models. These results suggest that scaling native omnimodal training can produce
unified systems that not only perceive and reason across modalities, but also interact and act in real time.
We hope Qwen3.5-Omni provides a strong foundation for future research on general-purpose omnimodal
agents.

8.1   Detailed Multilingual Evaluation Results

Multilingual ASR. As presented in Table 13, Qwen3.5-Omni demonstrates superior speech recognition
capabilities compared to state-of-the-art competitors on the FLEURS test set. Qwen3.5-Omni-Plus
achieves the lowest average WER of 6.6%, outperforming both Gemini-3.1-Pro (7.3%) and GPT-4o-
Transcribe (10.4%). It secures the best performance in the majority of languages, with particularly
significant margins in complex tonal and low-resource languages such as Cantonese (2.2% vs. 6.3%
for Gemini-3.1-Pro), Thai, and Vietnamese. Meanwhile, Qwen3.5-Omni-Flash offers a highly efficient
alternative, achieving an average WER of 10.8% that remains competitive against Gemini-3-Flash (10.5%).
Notably, Qwen3.5-Omni-Flash exhibits exceptional robustness in challenging scenarios, drastically
reducing errors in Cantonese (3.1% vs. 10.8% for Gemini-3-Flash) and maintaining strong performance in
Japanese and Korean, thereby highlighting its advantage for high-value Asian language pairs.

Multilingual Translation. As shown in Tables 14 and 15, the Qwen3.5-Omni series demonstrates
distinct advantages over state-of-the-art competitors on the FLEURS test set, particularly in Asian
languages and specific high-resource pairs. Qwen3.5-Omni-Plus exhibits comprehensive superiority
over Gemini-3.1-Pro in the many-to-many directions (en2xx/zh2xx), achieving higher average BLEU
scores in both English-to-XX (33.8 vs. 31.8) and Chinese-to-XX (21.4 vs. 19.6). It also leads in key xx2en
pairs such as Portuguese (49.4 vs. 47.7) and Indonesian (45.7 vs. 45.1). Although Gemini-3.1-Pro holds a
slight edge in overall xx2zh averages, Qwen3.5-Omni-Plus significantly outperforms it in critical Asian
languages, including Cantonese (+15.6 BLEU), Korean, and Japanese. Similarly, Qwen3.5-Omni-Flash
shows targeted strengths against Gemini-3-Flash. While maintaining competitive general performance, it
vastly surpasses Gemini in Cantonese translation across all directions (e.g., 37.5 vs. 22.4 in xx2zh and 37.3
vs. 26.7 in en2xx) and delivers better results in Japanese and Korean xx2zh tasks. These results underscore
Qwen3.5-Omni’s robust optimization for complex Asian linguistic structures and key regional languages.
