Kimi : Conversational AI from Moonshot AI known for processing ultra-long documents in one pass.

Beijing startup Moonshot AI launched Kimi in October 2023 as a Chinese-and-English AI assistant in the ChatGPT and Claude mold.

Its edge is digesting enormous inputs at once: paste a full book, research paper or webpage and it reasons across every page, with native image understanding and up to a million tokens of context.

The English-facing site kimi.com ships a K3 model built for agentic coding and knowledge work, open to overseas users through any browser.

What are Kimi K2.6's core capabilities?

Kimi K2.6 excels in both Chinese and English across coding, agentic tasks, and document analysis. It features 1M context, Agent Swarm for multi-agent workflows, and Deep Research mode. English performance is competitive with leading Western models on most benchmarks.

What makes Kimi's long-context feature unique?

Kimi supports analyzing extremely long documents (up to 2 million tokens), allowing users to upload entire books, research papers, or codebases for analysis. This is significantly longer than most Western LLMs' context windows.

Can I use Kimi from the US?

Kimi (kimi.moonshot.cn) requires a Chinese phone number for registration. The web interface and app are Chinese-only. It is designed for the Chinese market with strong Chinese document analysis capabilities.
