## Summary

Tencent's Hunyuan Speech team introduced Gander, a model that can keep a real‑time conversation going while a separate "brain" component works on complex tasks. The architecture splits responsibilities: a fast "cerebellum" manages speech, image and text input second‑by‑second, and a swappable "brain" handles reasoning, code generation or other agent functions. Users may interrupt at any moment, and the system decides whether to listen, speak or pause without a dedicated voice‑activity detector.

In the Full‑Duplex‑Bench v3 evaluation covering 100 scenarios, Gander interrupted users in only 8 % of cases, compared with 13.5 % for OpenAI's GPT‑Realtime and about 48 % for the weakest competitor. The model lagged behind on overall task accuracy, especially in video and audio understanding, which the researchers attribute to training that favoured fluid conversation over precise perception. Gander was trained on roughly 2.7 million examples. Tencent plans to publish the model weights and training data after completing its open‑source release process, and a GitHub repository already hosts the code and demos.

## Key points

- Gander interrupts users in only 8% of 100 Full‑Duplex‑Bench v3 scenarios, versus 13.5% for GPT‑Realtime.
- Model processes speech, images and text simultaneously using a “cerebellum” for conversation and a swappable “brain” for complex tasks.
- Tencent plans to open‑source Gander’s weights and training data; a GitHub repository already hosts the code.

## Why it matters

A conversational agent that can continue speaking while handling background reasoning reduces latency and improves user experience, addressing a core limitation of current voice assistants.
