Summary

This paper introduces Audio-Interaction, a unified streaming audio model that combines offline task execution with real-time audio instruction following via an end-to-end framework. It proposes SoundFlow for the perceive-decide-respond loop and evaluates competitive performance across benchmarks.

Audio is an inherently interactive modality, yet today's Large Audio Language Models (LALMs) are offline, and streaming audio models each handle only a single task such as streaming ASR or voice chatting. It is time to unify them into one online LALM: a model that, through an always-on perceive-decide-respond loop, listens to sound, environment, and instructions in real time and reacts on the fly. We formalize this regime as the Audio Interaction Model, and realize it with Audio-Interaction, a unified streaming model that retains offline task execution while adding online general audio instruction following, from dialogue to full voice chatting, deciding when to respond from the semantics of the stream. To enable this, we propose SoundFlow, a framework that instantiates the perceive-decide-respond loop end to end, from data to training to deployment, through streaming-native data construction, comprehension-aware training, and asynchronous low-latency inference for stable real-time interaction. We further construct StreamAudio-2M, a 2.6M-item streaming corpus spanning 7 fundamental abilities and 28 sub-tasks, and Proactive-Sound-Bench for evaluating proactive audio intervention. Across 8 benchmarks, Audio-Interaction preserves competitive performance on mainstream audio tasks while unlocking capabilities inaccessible to offline LALMs, including real-time ASR, streaming audio instruction following, and proactive help.

Abstract

A unified streaming audio model is developed that combines offline task execution with real-time audio instruction following through an end-to-end framework supporting multiple audio interaction capabilities.

Audio is an inherently interactive modality, yet today’sLarge Audio Language Models(LALMs) are offline, andstreaming audio modelseach handle only a single task such as streaming ASR or voice chatting. It is time to unify them into one online LALM: a model that, through an always-onperceive-decide-respond loop, listens to sound, environment, and instructions in real time and reacts on the fly. We formalize this regime as theAudio Interaction Model, and realize it with Audio-Interaction, a unified streaming model that retains offline task execution while adding online general audio instruction following, from dialogue to full voice chatting, deciding when to respond from the semantics of the stream. To enable this, we proposeSoundFlow, a framework that instantiates theperceive-decide-respond loopend to end, from data to training to deployment, throughstreaming-native data construction,comprehension-aware training, andasynchronous low-latency inferencefor stable real-time interaction. We further constructStreamAudio-2M, a 2.6M-item streaming corpus spanning 7 fundamental abilities and 28 sub-tasks, andProactive-Sound-Benchfor evaluating proactive audio intervention. Across 8 benchmarks, Audio-Interaction preserves competitive performance on mainstream audio tasks while unlocking capabilities inaccessible to offline LALMs, including real-time ASR, streaming audio instruction following, and proactive help.

Thinking Machines AI announces a research preview of interaction models, a new architecture designed for native, real-time human-AI collaboration across audio, video, and text. By replacing turn-based interfaces with a multi-stream, micro-turn design, the model aims to keep humans actively in the loop while delivering state-of-the-art intelligence and responsiveness.

This paper identifies that video-capable multimodal LLMs often appear to understand audio but actually rely on visual cues, a failure mode termed the audio-visual Clever Hans effect. It introduces Thud, an intervention-driven probing framework to diagnose this issue, and proposes an alignment recipe that improves audio-visual consistency by 28 percentage points.
