Kimi AI
🗒️ What is Kimi AI?
Moonshot AI's flagship assistant, powered by the trillion-parameter K2.5 model -- agentic coding, deep research, and everyday chat at a fraction of GPT and Claude's API cost.
Kimi AI is built by Moonshot AI, a Beijing-based lab valued at roughly $18 billion, and has grown from a niche Chinese chatbot into a globally used assistant in under two years. Its K2.5 model uses a Mixture-of-Experts architecture with 1 trillion total parameters but activates only 32 billion per request, ranking competitively with GPT-5.4 and Claude Sonnet 4.6 on benchmarks while costing 4-17x less to run via the API. Kimi also offers a 300-subagent Agent Swarm mode and a desktop app that can execute tasks directly on your machine.
Kimi AI is particularly strong at free tier includes unlimited basic chat, file uploads, and web search, k2.5 costs 4-17x less than GPT-5.4 and 5-6x less than Claude Sonnet 4.6 via the API for comparable benchmark performance, and 300-subagent Agent Swarm mode for large parallel agentic tasks, making it a popular choice for cost-sensitive teams running high-volume API workloads and agentic coding tasks via Kimi Code. One thing to keep in mind: built by a Chinese company, which may raise data-residency or compliance concerns for some organizations.
