Tencent: Hy3 preview

Tencent Hy3 preview is a text-in, text-out model with a 262,144-token context window, support for tool use, and a reasoning mode. Structured output support is unconfirmed, and there is no indication of open weights. The context window is large enough to handle long documents or extended multi-turn sessions without chunking. On benchmarks, the model has a blended score of 55.3, but that figure comes from a single benchmark, so treat it as a preliminary signal rather than a settled verdict. Pricing is low: $0.063 per million input tokens and $0.21 per million output tokens. Teams running high-volume, tool-calling or reasoning workloads on a tight budget may find that ratio worth testing, but anyone needing well-validated performance across diverse tasks should wait for broader benchmark coverage before committing.
