JoyAI-VL-Interaction

The first open, vision-driven real-time interaction model — it watches a live video stream and decides on its own when to speak, stay silent, or delegate. While enabling online, real-time interaction, this release also delivers powerful offline video understanding, making it the most comprehensive open-source model for video-related capabilities in the 8B parameter class.

Overview

Most large models today are turn-based: they answer only when you ask. But many moments in the real world don't wait for a question — a fire starts on a security feed, someone falls, a product flashes by in a livestream. Once missed, the moment is gone.

JoyAI-VL-Interaction is built for exactly these moments. It is an 8B-scale, vision-first interaction model that continuously watches a live video stream and, every second, decides on its own to take one of three actions:

• Speak — respond when something is worth saying
• Stay silent — keep watching when nothing warrants a response (a first-class, trained action)
• Delegate — hand a hard subtask to a background model/agent, keep watching, and weave the result back in when it returns

The decision of when to act is learned inside the model (from second-by-second time-aligned data + RL), not bolted on by an external turn-detector or polling loop. Vision is the first-class driver; speech (ASR/TTS) is treated as pluggable I/O.

To our knowledge, this is the first open, vision-driven interaction model released together with its training recipe, data, and a complete deployable system.

Model Performance

Offline Video Evaluation

Across 26 standard video understanding benchmarks, JoyAI-VL-Interaction achieves an average score of 57.53, outperforming Qwen3-VL-8B-Instruct at 54.16 by 3.37 points.
