PRODUCT OVERVIEW

What is Kimi?

Kimi is the model-as-a-service open platform from Moonshot AI, giving developers API access to the Kimi K3, K2.7 Code and K2.6 models. It provides OpenAI-compatible Responses and Chat Completions APIs plus an Anthropic-compatible Messages API, so teams can call models over HTTP or with the OpenAI and Anthropic SDKs. Built-in official tools include web search, memory, Excel and CSV analysis, Python code execution, URL-to-markdown fetching and unit conversion. The platform targets software engineering, deep research, legal and compliance document workflows, and conversational insight analysis, with a playground for testing prompts without code. Billing is pay-as-you-go per token, with separate input, output and cache pricing; self-service top-up suits individual developers and small teams, while enterprise services add elastic rate quotas, SLA guarantees and dedicated support.
