Kimi K2 Thinking pushes the K2 line toward agentic reasoning that holds up over long horizons. On a trillion-parameter MoE backbone (32B active) with a 256K context, it weaves step-by-step thought together with dynamic tool calls, so it can drive autonomous research, coding and writing across hundreds of sequential actions without losing the thread. It posts strong open-source results on HLE, BrowseComp, SWE-Multilingual and LiveCodeBench.
Kimi K2 Thinking is a good fit for autonomous agents, long-horizon reasoning and complex tool workflows. It supports tool (function) calling and explicit reasoning. 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: $0.6 per million input tokens and $2.5 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.
Kimi K2 Thinking is Moonshot AI’s most advanced open reasoning model to date, extending the K2 series into agentic, long-horizon reasoning. Built on the trillion-parameter Mixture-of-Experts (MoE) architecture introduced in...
