What is Kimi API Platform?
Kimi API Platform is the developer access point for Kimi's large language models. It provides API access to the Kimi K3 flagship model with a 1M-token context window, plus K2.7 Code (256k context) for coding tasks and K2.6 (256k context) as a general-purpose model that accepts both vision and text input.
Developers call the models through the API and are billed per million tokens for input and output, with a separate cache-hit price for repeated request prefixes. The platform also offers a set of official tools that models can call, including web search, a Python code runner, a JavaScript sandbox, Excel and CSV analysis, memory storage, URL content extraction, unit and currency conversion, and date handling. The documentation lists example uses such as agentic programming, deep research, legal document work, and conversation analysis.
