Hy3

Hy3 is a 295B-parameter mixture-of-experts model from Tencent with 21B active parameters that supports configurable reasoning effort for complex problem-solving.

Strengths

Excels at reasoning tasks and agentic workflows with a large context window of ~200K tokens, allowing it to handle extended documents and multi-step reasoning chains.

Best for

Complex reasoning, multi-step problem solving, and production agentic systems where adjustable reasoning depth is valuable.

Limitations

As a sparse mixture-of-experts model, inference performance depends on routing efficiency, and may not be optimal for simple completion tasks that don't benefit from its reasoning capabilities.
