Kimi

Kimi is the consumer-facing AI assistant from Moonshot AI, a Beijing-based lab that has spent the last two years pushing long-context language models. The web app bundles a conversational chat surface with specialized modes for code, document analysis, slide and website generation, spreadsheets, deep research, and an 'Agent Swarm' coordinator that lets multiple sub-agents tackle a task in parallel. The current model under the hood is the K2 family (K2.6 general, K2.7 Code, K2.5 multimodal with thinking/non-thinking modes).

It is most interesting to people who want a ChatGPT-style workspace that leans hard on long-document ingestion and agentic workflows rather than image generation or voice. The web chat is free; the developer side lives at platform.kimi.ai with pay-as-you-go pricing roughly in the $0.60-$4.00 per million tokens range depending on model. Earlier K2 weights have been released openly by Moonshot on Hugging Face, but the production K2.6/K2.7 endpoints behind Kimi.com are proprietary.

For English-speaking users the main caveats are that Kimi was built China-first, so some integrations, billing flows, and mobile app distribution are smoother for users in Asia, and the agent/sheets/slides features are newer than the core chat and still evolving.
