Kimi K2 0905 is the September refresh of Moonshot AI's trillion-parameter MoE model (32B active), which stretches the context from 128K up to 256K tokens. The update tightens agentic coding. It is more accurate and generalizes better across different scaffolds. And lifts front-end code output for web, 3D and similar work, all while preserving the tool-use and reasoning strengths of the K2 line.

Kimi K2 0905 is a good fit for long-context agentic coding, front-end generation and tool use. It supports tool (function) calling. The model works with a context window of about 262K tokens, so it comfortably handles long inputs. It is served through Hormouz behind an OpenAI-compatible API. Just point your base URL at Hormouz and drop in a Hormouz key, and existing OpenAI SDK code runs unchanged.

Pricing is usage-based: $1 per million input tokens and $3 per million output tokens, billed only for what you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
