## Overview ### Introduction

Qwen3-Omni is the natively end-to-end multilingual omni-modal foundation models. It processes text, images, audio, and video, and delivers real-time streaming responses in both text and natural speech. We introduce several architectural upgrades to improve performance and efficiency. Key features: * **State-of-the-art across modalities**: Early text-first pretraining and mixed multimodal training provide native multimodal support. While achieving strong audio and audio-video results, unimodal text and image performance does not regress. Reaches SOTA on 22 of 36 audio/video benchmarks and open-source SOTA on 32 of 36; ASR, audio understanding, and voice conversation performance is comparable to Gemini 2.5 Pro. * **Multilingual**: Supports 119 text languages, 19 speech input languages, and 10 speech output languages. - **Speech Input**: English, Chinese, Korean, Japanese, German, Russian, Italian, French, Spanish, Portuguese, Malay, Dutch, Indonesian, Turkish, Vietnamese, Cantonese, Arabic, Urdu. - **Speech Output**: English, Chinese, French, German, Russian, Italian, Spanish, Portuguese, Japanese, Korean. * **Novel Architecture**: MoE-based Thinker–Talker design with AuT pretraining for strong general representations, plus a multi-codebook design that drives latency to a minimum. * **Real-time Audio/Video Interaction**: Low-latency streaming with natural turn-taking and immediate text or speech responses. * **Flexible Control**: Customize behavior via system prompts for fine-grained control and easy adaptation. * **Detailed Audio Captioner**: Qwen3-Omni-30B-A3B-Captioner is now open source: a general-purpose, highly detailed, low-hallucination audio captioning model that fills a critical gap in the open-source community. ### Model Architecture

For more information, you can refer to the model's [cookbook](https://github.com/QwenLM/Qwen3-Omni/blob/main/cookbooks/omni_captioner.ipynb). | During loading in Hugging Face Transformers or vLLM, model weights will be automatically downloaded based on the model name. However, if your runtime environment is not conducive to downloading weights during execution, you can refer to the following commands to manually download the model weights to a local directory: ```bash # Download through ModelScope (recommended for users in Mainland China) pip install -U modelscope modelscope download --model Qwen/Qwen3-Omni-30B-A3B-Instruct --local_dir ./Qwen3-Omni-30B-A3B-Instruct modelscope download --model Qwen/Qwen3-Omni-30B-A3B-Thinking --local_dir ./Qwen3-Omni-30B-A3B-Thinking modelscope download --model Qwen/Qwen3-Omni-30B-A3B-Captioner --local_dir ./Qwen3-Omni-30B-A3B-Captioner # Download through Hugging Face pip install -U "huggingface_hub[cli]" huggingface-cli download Qwen/Qwen3-Omni-30B-A3B-Instruct --local-dir ./Qwen3-Omni-30B-A3B-Instruct huggingface-cli download Qwen/Qwen3-Omni-30B-A3B-Thinking --local-dir ./Qwen3-Omni-30B-A3B-Thinking huggingface-cli download Qwen/Qwen3-Omni-30B-A3B-Captioner --local-dir ./Qwen3-Omni-30B-A3B-Captioner ``` ### Transformers Usage #### Installation The Hugging Face Transformers code for Qwen3-Omni has been successfully merged, but the PyPI package has not yet been released. Therefore, you need to install it from source using the following command. We strongly recommend that you **create a new Python environment** to avoid environment runtime issues. ```bash # If you already have transformers installed, please uninstall it first, or create a new Python environment # pip uninstall transformers pip install git+https://github.com/huggingface/transformers pip install accelerate ``` We offer a toolkit to help you handle various types of audio and visual input more conveniently, providing an API-like experience. This includes support for base64, URLs, and interleaved audio, images, and videos. You can install it using the following command and make sure your system has `ffmpeg` installed: ```bash pip install qwen-omni-utils -U ``` Additionally, we recommend using FlashAttention 2 when running with Hugging Face Transformers to reduce GPU memory usage. However, if you are primarily using [vLLM](#vllm-usage) for inference, this installation is not necessary, as vLLM includes FlashAttention 2 by default. ```bash pip install -U flash-attn --no-build-isolation ``` Also, you should have hardware that is compatible with FlashAttention 2. Read more about it in the official documentation of the [FlashAttention repository](https://github.com/Dao-AILab/flash-attention). FlashAttention 2 can only be used when a model is loaded in `torch.float16` or `torch.bfloat16`. #### Code Snippet Here is a code snippet to show you how to use Qwen3-Omni with `transformers` and `qwen_omni_utils`: ```python import soundfile as sf from transformers import Qwen3OmniMoeForConditionalGeneration, Qwen3OmniMoeProcessor from qwen_omni_utils import process_mm_info MODEL_PATH = "Qwen/Qwen3-Omni-30B-A3B-Instruct" # MODEL_PATH = "Qwen/Qwen3-Omni-30B-A3B-Thinking" model = Qwen3OmniMoeForConditionalGeneration.from_pretrained( MODEL_PATH, dtype="auto", device_map="auto", attn_implementation="flash_attention_2", ) processor = Qwen3OmniMoeProcessor.from_pretrained(MODEL_PATH) conversation = [ { "role": "user", "content": [ {"type": "image", "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-Omni/demo/cars.jpg"}, {"type": "audio", "audio": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-Omni/demo/cough.wav"}, {"type": "text", "text": "What can you see and hear? Answer in one short sentence."} ], }, ] # Set whether to use audio in video USE_AUDIO_IN_VIDEO = True # Preparation for inference text = processor.apply_chat_template(conversation, add_generation_prompt=True, tokenize=False) audios, images, videos = process_mm_info(conversation, use_audio_in_video=USE_AUDIO_IN_VIDEO) inputs = processor(text=text, audio=audios, images=images, videos=videos, return_tensors="pt", padding=True, use_audio_in_video=USE_AUDIO_IN_VIDEO) inputs = inputs.to(model.device).to(model.dtype) # Inference: Generation of the output text and audio text_ids, audio = model.generate(**inputs, speaker="Ethan", thinker_return_dict_in_generate=True, use_audio_in_video=USE_AUDIO_IN_VIDEO) text = processor.batch_decode(text_ids.sequences[:, inputs["input_ids"].shape[1] :], skip_special_tokens=True, clean_up_tokenization_spaces=False) print(text) if audio is not None: sf.write( "output.wav", audio.reshape(-1).detach().cpu().numpy(), samplerate=24000, ) ``` Here are some more advanced usage examples. You can expand the sections below to learn more.

Batch inference

The model can batch inputs composed of mixed samples of various types such as text, images, audio, and videos as input when `return_audio=False` is set. Here is an example. ```python from transformers import Qwen3OmniMoeForConditionalGeneration, Qwen3OmniMoeProcessor from qwen_omni_utils import process_mm_info MODEL_PATH = "Qwen/Qwen3-Omni-30B-A3B-Instruct" # MODEL_PATH = "Qwen/Qwen3-Omni-30B-A3B-Thinking" model = Qwen3OmniMoeForConditionalGeneration.from_pretrained( MODEL_PATH, dtype="auto", device_map="auto", attn_implementation="flash_attention_2", ) model.disable_talker() processor = Qwen3OmniMoeProcessor.from_pretrained(MODEL_PATH) # Conversation with image only conversation1 = [ { "role": "user", "content": [ {"type": "image", "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-Omni/demo/cars.jpg"}, {"type": "text", "text": "What can you see in this image? Answer in one sentence."}, ] } ] # Conversation with audio only conversation2 = [ { "role": "user", "content": [ {"type": "audio", "audio": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-Omni/demo/cough.wav"}, {"type": "text", "text": "What can you hear in this audio?"}, ] } ] # Conversation with pure text and system prompt conversation3 = [ { "role": "system", "content": [ {"type": "text", "text": "You are Qwen-Omni."} ], }, { "role": "user", "content": "Who are you?" } ] # Conversation with mixed media conversation4 = [ { "role": "user", "content": [ {"type": "image", "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-Omni/demo/cars.jpg"}, {"type": "audio", "audio": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-Omni/demo/cough.wav"}, {"type": "text", "text": "What can you see and hear? Answer in one sentence."} ], } ] # Combine messages for batch processing conversations = [conversation1, conversation2, conversation3, conversation4] # Set whether to use audio in video USE_AUDIO_IN_VIDEO = True # Preparation for batch inference text = processor.apply_chat_template(conversations, add_generation_prompt=True, tokenize=False) audios, images, videos = process_mm_info(conversations, use_audio_in_video=USE_AUDIO_IN_VIDEO) inputs = processor(text=text, audio=audios, images=images, videos=videos, return_tensors="pt", padding=True, use_audio_in_video=USE_AUDIO_IN_VIDEO) inputs = inputs.to(model.device).to(model.dtype) # Batch inference does not support returning audio text_ids, audio = model.generate(**inputs, return_audio=False, thinker_return_dict_in_generate=True, use_audio_in_video=USE_AUDIO_IN_VIDEO) text = processor.batch_decode(text_ids.sequences[:, inputs["input_ids"].shape[1] :], skip_special_tokens=True, clean_up_tokenization_spaces=False) print(text) ```

Use audio output or not

The model supports both text and audio outputs. If users do not need audio outputs, they can call `model.disable_talker()` after initializing the model. This option will save about `10GB` of GPU memory, but the `return_audio` option for the `generate` function will only allow `False`. ```python model = Qwen3OmniMoeForConditionalGeneration.from_pretrained( "Qwen/Qwen3-Omni-30B-A3B-Instruct", dtype="auto", device_map="auto", attn_implementation="flash_attention_2", ) model.disable_talker() ``` For a more flexible experience, we recommend that users decide whether to return audio when the `generate` function is called. If `return_audio` is set to `False`, the model will only return text outputs, resulting in faster text responses. ```python model = Qwen3OmniMoeForConditionalGeneration.from_pretrained( "Qwen/Qwen3-Omni-30B-A3B-Instruct", dtype="auto", device_map="auto", attn_implementation="flash_attention_2", ) ... text_ids, _ = model.generate(..., return_audio=False)```

Change voice type of output audio

Qwen3-Omni supports changing the voice of the output audio. The `"Qwen/Qwen3-Omni-30B-A3B-Instruct"` checkpoint supports three voice types as follows: | Voice Type | Gender | Description | |------------|--------|-------------| | Ethan | Male | A bright, upbeat voice with infectious energy and a warm, approachable vibe. | | Chelsie | Female | A honeyed, velvety voice that carries a gentle warmth and luminous clarity. | | Aiden | Male | A warm, laid-back American voice with a gentle, boyish charm. | Users can use the `speaker` parameter of the `generate` function to specify the voice type. By default, if `speaker` is not specified, the voice type is `Ethan`. ```python text_ids, audio = model.generate(..., speaker="Ethan") ``` ```python text_ids, audio = model.generate(..., speaker="Chelsie") ``` ```python text_ids, audio = model.generate(..., speaker="Aiden") ```

### vLLM Usage #### Installation We strongly recommend using vLLM for inference and deployment of the Qwen3-Omni series models. Since our code is currently in the pull request stage, and **audio output inference support for the Instruct model will be released in the near future**, you can follow the commands below to install vLLM from source. Please note that we recommend you **create a new Python environment** to avoid runtime environment conflicts and incompatibilities. For more details on compiling vLLM from source, please refer to the [vLLM official documentation](https://docs.vllm.ai/en/latest/getting_started/installation/gpu.html#set-up-using-python-only-build-without-compilation). ```bash git clone -b qwen3_omni https://github.com/wangxiongts/vllm.git cd vllm pip install -r requirements/build.txt pip install -r requirements/cuda.txt export VLLM_PRECOMPILED_WHEEL_LOCATION=https://wheels.vllm.ai/a5dd03c1ebc5e4f56f3c9d3dc0436e9c582c978f/vllm-0.9.2-cp38-abi3-manylinux1_x86_64.whl VLLM_USE_PRECOMPILED=1 pip install -e . -v --no-build-isolation # If you meet an "Undefined symbol" error while using VLLM_USE_PRECOMPILED=1, please use "pip install -e . -v" to build from source. # Install the Transformers pip install git+https://github.com/huggingface/transformers pip install accelerate pip install qwen-omni-utils -U pip install -U flash-attn --no-build-isolation ``` #### Inference You can use the following code for vLLM inference. The `limit_mm_per_prompt` parameter specifies the maximum number of each modality's data allowed per message. Since vLLM needs to pre-allocate GPU memory, larger values will require more GPU memory; if OOM issues occur, try reducing this value. Setting `tensor_parallel_size` greater than one enables multi-GPU parallel inference, improving concurrency and throughput. In addition, `max_num_seqs` indicates the number of sequences that vLLM processes in parallel during each inference step. A larger value requires more GPU memory but enables higher batch inference speed. For more details, please refer to the [vLLM official documentation](https://docs.vllm.ai/en/latest/api/vllm/index.html#vllm.LLM). Below is a simple example of how to run Qwen3-Omni with vLLM: ```python import os import torch from vllm import LLM, SamplingParams from transformers import Qwen3OmniMoeProcessor from qwen_omni_utils import process_mm_info if __name__ == '__main__': # vLLM engine v1 not supported yet os.environ['VLLM_USE_V1'] = '0' MODEL_PATH = "Qwen/Qwen3-Omni-30B-A3B-Instruct" # MODEL_PATH = "Qwen/Qwen3-Omni-30B-A3B-Thinking" llm = LLM( model=MODEL_PATH, trust_remote_code=True, gpu_memory_utilization=0.95, tensor_parallel_size=torch.cuda.device_count(), limit_mm_per_prompt={'image': 3, 'video': 3, 'audio': 3}, max_num_seqs=8, max_model_len=32768, seed=1234, ) sampling_params = SamplingParams( temperature=0.6, top_p=0.95, top_k=20, max_tokens=16384, ) processor = Qwen3OmniMoeProcessor.from_pretrained(MODEL_PATH) messages = [ { "role": "user", "content": [ {"type": "video", "video": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-Omni/demo/draw.mp4"} ], } ] text = processor.apply_chat_template( messages, tokenize=False, add_generation_prompt=True, ) audios, images, videos = process_mm_info(messages, use_audio_in_video=True) inputs = { 'prompt': text, 'multi_modal_data': {}, "mm_processor_kwargs": { "use_audio_in_video": True, }, } if images is not None: inputs['multi_modal_data']['image'] = images if videos is not None: inputs['multi_modal_data']['video'] = videos if audios is not None: inputs['multi_modal_data']['audio'] = audios outputs = llm.generate([inputs], sampling_params=sampling_params) print(outputs[0].outputs[0].text) ``` Here are some more advanced usage examples. You can expand the sections below to learn more.

Batch inference

Using vLLM enables fast batch inference, which can help you efficiently process large volumes of data or conduct benchmarking. Refer to the following code example: ```python import os import torch from vllm import LLM, SamplingParams from transformers import Qwen3OmniMoeProcessor from qwen_omni_utils import process_mm_info def build_input(processor, messages, use_audio_in_video): text = processor.apply_chat_template( messages, tokenize=False, add_generation_prompt=True, ) audios, images, videos = process_mm_info(messages, use_audio_in_video=use_audio_in_video) inputs = { 'prompt': text, 'multi_modal_data': {}, "mm_processor_kwargs": { "use_audio_in_video": use_audio_in_video, }, } if images is not None: inputs['multi_modal_data']['image'] = images if videos is not None: inputs['multi_modal_data']['video'] = videos if audios is not None: inputs['multi_modal_data']['audio'] = audios return inputs if __name__ == '__main__': # vLLM engine v1 not supported yet os.environ['VLLM_USE_V1'] = '0' MODEL_PATH = "Qwen/Qwen3-Omni-30B-A3B-Instruct" # MODEL_PATH = "Qwen/Qwen3-Omni-30B-A3B-Thinking" llm = LLM( model=MODEL_PATH, trust_remote_code=True, gpu_memory_utilization=0.95, tensor_parallel_size=torch.cuda.device_count(), limit_mm_per_prompt={'image': 3, 'video': 3, 'audio': 3}, max_num_seqs=8, max_model_len=32768, seed=1234, ) sampling_params = SamplingParams( temperature=0.6, top_p=0.95, top_k=20, max_tokens=16384, ) processor = Qwen3OmniMoeProcessor.from_pretrained(MODEL_PATH) # Conversation with image only conversation1 = [ { "role": "user", "content": [ {"type": "image", "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-Omni/demo/cars.jpg"}, {"type": "text", "text": "What can you see in this image?

vLLM Serve Usage

vLLM serve for Qwen3-Omni currently only supports the thinker model. The `use_audio_in_video` parameter is not available in vLLM serve; you can handle this by separately passing video and audio inputs for processing. You can start vLLM serve through the following command: ```bash # Qwen3-Omni-30B-A3B-Instruct for single GPU vllm serve Qwen/Qwen3-Omni-30B-A3B-Instruct --port 8901 --host 127.0.0.1 --dtype bfloat16 --max-model-len 32768 --allowed-local-media-path / -tp 1 # Qwen3-Omni-30B-A3B-Instruct for multi-GPU (example on 4 GPUs) vllm serve Qwen/Qwen3-Omni-30B-A3B-Instruct --port 8901 --host 127.0.0.1 --dtype bfloat16 --max-model-len 65536 --allowed-local-media-path / -tp 4 # Qwen/Qwen3-Omni-30B-A3B-Thinking for single GPU vllm serve Qwen/Qwen3-Omni-30B-A3B-Thinking --port 8901 --host 127.0.0.1 --dtype bfloat16 --max-model-len 32768 --allowed-local-media-path / -tp 1 # Qwen/Qwen3-Omni-30B-A3B-Thinking for multi-GPU (example on 4 GPUs) vllm serve Qwen/Qwen3-Omni-30B-A3B-Thinking --port 8901 --host 127.0.0.1 --dtype bfloat16 --max-model-len 65536 --allowed-local-media-path / -tp 4 ``` Then you can use the chat API as below (via curl, for example): ```bash curl http://localhost:8901/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{ "messages": [ {"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": [ {"type": "image_url", "image_url": {"url": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-Omni/demo/cars.jpg"}}, {"type": "audio_url", "audio_url": {"url": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen3-Omni/demo/cough.wav"}}, {"type": "text", "text": "What can you see and hear? Answer in one sentence."} ]} ] }' ```

### Usage Tips (Recommended Reading) #### Minimum GPU memory requirements | Model | Precision | 15s Video | 30s Video | 60s Video | 120s Video | |------------------------------|-----------| --------- | --------- | --------- | --------- | | Qwen3-Omni-30B-A3B-Instruct | BF16 | 78.85 GB | 88.52 GB | 107.74 GB | 144.81 GB | | Qwen3-Omni-30B-A3B-Thinking | BF16 | 68.74 GB | 77.79 GB | 95.76 GB | 131.65 GB | **Note**: The table above presents the theoretical minimum memory requirements for inference with `transformers` and `BF16` precision, tested with `attn_implementation="flash_attention_2"`. The Instruct model includes both the **thinker** and **talker** components, whereas the Thinking model includes only the **thinker** part. #### Prompt for Audio-Visual Interaction When using Qwen3-Omni for audio-visual multimodal interaction, where the input consists of a video and its corresponding audio (with the audio serving as a query), we recommend using the **following system prompt**. This setup helps the model maintain high reasoning capability while better assuming interactive roles such as a smart assistant. Additionally, the text generated by the thinker will be more readable, with a natural, conversational tone and without complex formatting that is difficult to vocalize, leading to more stable and fluent audio output from the talker. You can customize the `user_system_prompt` field in the system prompt to include character settings or other role-specific descriptions as needed. ``` user_system_prompt = "You are Qwen-Omni, a smart voice assistant created by Alibaba Qwen." message = { "role": "system", "content": [ {"type": "text", "text": f"{user_system_prompt} You are a virtual voice assistant with no gender or age.\nYou are communicating with the user.\nIn user messages, “I/me/my/we/our” refer to the user and “you/your” refer to the assistant. In your replies, address the user as “you/your” and yourself as “I/me/my”; never mirror the user’s pronouns—always shift perspective. Keep original pronouns only in direct quotes; if a reference is unclear, ask a brief clarifying question.\nInteract with users using short(no more than 50 words), brief, straightforward language, maintaining a natural tone.\nNever use formal phrasing, mechanical expressions, bullet points, overly structured language. \nYour output must consist only of the spoken content you want the user to hear. \nDo not include any descriptions of actions, emotions, sounds, or voice changes. \nDo not use asterisks, brackets, parentheses, or any other symbols to indicate tone or actions. \nYou must answer users' audio or text questions, do not directly describe the video content. \nYou should communicate in the same language strictly as the user unless they request otherwise.\nWhen you are uncertain (e.g., you can't see/hear clearly, don't understand, or the user makes a comment rather than asking a question), use appropriate questions to guide the user to continue the conversation.\nKeep replies concise and conversational, as if talking face-to-face."} ] } ``` #### Best Practices for the Thinking Model The `Qwen3-Omni-30B-A3B-Thinking` model is primarily designed for understanding and interacting with multimodal inputs, including text, audio, image, and video. To achieve optimal performance, we recommend that users include an explicit textual instruction or task description in each round of dialogue alongside the multimodal input. This helps clarify the intent and significantly enhances the model's ability to leverage its reasoning capabilities. For example: ```python messages = [ { "role": "user", "content": [ {"type": "audio", "audio": "/path/to/audio.wav"}, {"type": "image", "image": "/path/to/image.png"}, {"type": "video", "video": "/path/to/video.mp4"}, {"type": "text", "text": "Analyze this audio, image, and video together."}, ], } ] ``` #### Use audio in video In multimodal interaction, user-provided videos are often accompanied by audio (such as spoken questions or sounds from events in the video). This information helps the model provide a better interactive experience. We provide the following options for users to decide whether to use the audio from a video. ```python # In data preprocessing audios, images, videos = process_mm_info(messages, use_audio_in_video=True) ``` ```python # For Transformers text = processor.apply_chat_template(messages, add_generation_prompt=True, tokenize=False) inputs = processor(text=text, audio=audios, images=images, videos=videos, return_tensors="pt", padding=True, use_audio_in_video=True) text_ids, audio = model.generate(..., use_audio_in_video=True) # For vLLM text = processor.apply_chat_template(messages, add_generation_prompt=True, tokenize=False) inputs = { 'prompt': text, 'multi_modal_data': {}, "mm_processor_kwargs": { "use_audio_in_video": True, }, } ``` It is worth noting that during a multi-round conversation, the `use_audio_in_video` parameter must be set consistently across these steps; otherwise, unexpected results may occur. ## Evaluation ### Performance of Qwen3-Omni Qwen3-Omni maintains state-of-the-art performance on text and visual modalities without degradation relative to same-size single-model Qwen counterparts. Across 36 audio and audio-visual benchmarks, it achieves open-source SOTA on 32 and sets the SOTA on 22, outperforming strong closed-source systems such as Gemini 2.5 Pro and GPT-4o.

### Setting for Evaluation * **Decoding Strategy**: For the Qwen3-Omni series across all evaluation benchmarks, `Instruct` models use greedy decoding during generation without sampling. For `Thinking` models, the decoding parameters should be taken from the `generation_config.json` file in the checkpoint. * **Benchmark-Specific Formatting**: For the majority of evaluation benchmarks, they come with their own ChatML formatting to embed the question or prompt. It should be noted that all video data are set to `fps=2` during evaluation. * **Default Prompts**: For tasks in certain benchmarks that do not include a prompt, we use the following prompt settings: | Task Type | Prompt | | :--- | :--- | | Auto Speech Recognition (ASR) for Chinese | 请将这段中文语音转换为纯文本。 | | Auto Speech Recognition (ASR) for Other languages | Transcribe the audio into text. | | Speech-to-Text Translation (S2TT) | Listen to the provided speech and produce a translation in text. | | Song Lyrics Recognition | Transcribe the song lyrics into text without any punctuation, separate lines with line breaks, and output only the lyrics without additional explanations. | * **System Prompt**: No `system prompt` should be set for any evaluation benchmark. * **Input Sequence**: The question or prompt should be input as user text. Unless otherwise specified by the benchmark, the text should come **after** multimodal data in the sequence. For example: ```python messages = [ { "role": "user", "content": [ {"type": "audio", "audio": "/path/to/audio.wav"}, {"type": "image", "image": "/path/to/image.png"}, {"type": "video", "video": "/path/to/video.mp4"}, {"type": "text", "text": "Describe the audio, image and video."}, ], }, ] ```
