Hy3 is Tencent's 295B mixture-of-experts model with 21B active parameters, built for reasoning, agent workflows and production use. It answers directly by default and switches to low or high chain-of-thought for hard maths, coding and multi-step problems. Over a 256K context it tracks references and constraints across many turns and calls tools reliably in different agent frameworks.

It accepts text input and returns text, and supports tool calling, structured JSON output and streaming. Reasoning can be switched on when a problem needs more thought and left off when speed matters. Hy3 is commonly used for coding, document processing, multi-turn agents, maths and cost-sensitive production workloads. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.

Pricing is usage-based: $0.132 per million input tokens and $0.528 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.

Hy3 is a 295B-parameter Mixture-of-Experts model from Tencent (21B active, 192 experts with top-8 routing) built for reasoning, agentic workflows, and real-world production use. It supports a configurable reasoning effort:...
