Tencent's Hy4 agent plugs into WeCom and reads chats, emails, calendars, docs and meeting notes—one prompt turns all of it into a daily focus board.
Two standout demos:
- It rebuilt a 3D mouse embryo from 7 million cells in 1.5 hours on a single machine.
- Paired with Tencent's Hyra 2.0 harness, Hy4 trained a smaller model on its own that beat Tencent's official baseline on multiple benchmarks, described by Tencent as groundwork for "recursive self-improvement".
