How can we build a unified omnimodal large language model that seamlessly integrates understanding, reasoning, generation, and action across text, images, audio, and audio-visual inputs?
核心方法
{'approach': 'The model employs a Thinker-Talker architecture with Hybrid-Attention MoE design, supporting 256k-token long-context and using multicodebook codec representation with ARIA technique for text-speech alignment. Training involves three-stage pretraining on 4 trillion tokens across modalities, followed by post-training with specialist distillation, on-policy distillation, and interaction-aligned reinforcement learning on over 100 million hours of audio-visual data.', 'key_components': [], 'section_ids': ['sec_2', 'sec_19']}

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 training data scale (100+ million hours audio-visual) is stated but not fully quantified in a consolidated table. Agentic capabilities like WebSearch and FunctionCall are claimed but lack specific benchmark results - only OmniGAIA tool-use (57.2%
