Official access documentation

What you can build

Try Hy4 on a bounded workflow that combines image understanding with tool use, and separately evaluate long-context task completion before adopting it.

Limitations

Tencent says model weights and system cards are planned for release in the coming days, so open-weight access and the final system documentation were not yet available at verification. Capability and benchmark statements are Tencent's own claims.
