Kimi (Moonshot)
Moonshot's Kimi assistant and the open-weight Kimi K2 model family — a long-context (256K) MoE model explicitly trained for tool calling and agentic behaviour, surfaced through the Kimi consumer product line (Deep Research, Agent Swarm, Kimi Code, OK Computer).
Description
Kimi began in 2023 as Moonshot AI's chatbot known for 128K-token context; subsequent versions raised the window to 256K and added multimodal text/image/video input. Kimi K2 (released July 2025) is the open-weight 1T-total / 32B-active MoE model behind the product, explicitly trained for tool use and autonomous problem-solving and licensed permissively. The Kimi consumer surface bundles long-context chat with Deep Research, Agent Swarm, Slides/Docs/Sheets/Websites generation, and a sub-product called OK Computer that can build multi-page sites and editable slides from prompts and process up to 1M rows of input data. Public English documentation of the underlying API's tool-call schema redirects between several domains (platform.moonshot.cn → platform.kimi.com → platform.kimi.ai) and several pages were not directly fetchable; primary technical evidence here comes from the Kimi K2 model documentation.
Solution
Two surfaces. (1) Kimi consumer app: Moonshot-hosted assistant; user starts a chat or invokes a sub-product (Deep Research, Agent Swarm, OK Computer); model autonomously calls internal tools and produces multi-modal artifacts. (2) Kimi K2 API: standard chat-completions tool-call loop where the model autonomously decides when and how to invoke tools, designed for drop-in general chat and agentic experiences.
Primary use cases
- long-context document analysis and Q&A
- agentic tool-calling deployments via Kimi K2 open weights
- Deep Research and Agent Swarm consumer workflows
- AI-built slides, websites, sheets and docs from prompts
