Kimi K3
Moonshot's 2.8-trillion-parameter multimodal reasoning flagship with always-on thinking — the largest open-weight model ever released and the closest Chinese challenger to the Western frontier.
Kimi — the most intelligent open weights in the world.
Moonshot AI builds the Kimi family. Kimi K3 is the most intelligent open-weight model released to date — #4 overall on aggregate intelligence at launch — and Kimi K2.7 Code is a dedicated coding model that rivals models many times its price.

Kimi K3 ($3/$15) — the most intelligent open-weight model released to date, #4 overall on aggregate intelligence at launch with a 1M context. For coding specifically, Kimi K2.7 Code ($0.95/$4) is the better value: strong agentic coding at a fraction of K3's price.
The weights are open, but Kimi K3 is 2.8T parameters — impractical to self-host for almost everyone. In practice you access Kimi via the first-party API (platform.moonshot.ai), kimi.com for consumer use, or the Kimi Code subscription ($19/month).
Kimi K3 ranked #4 on aggregate intelligence at launch — above most closed models, below Claude Opus 5 and GPT-5.6 Sol. It is the strongest answer to 'what is the smartest model with open weights?' For pure coding, Claude leads on SWE-Bench Pro and K2.7 Code competes on value rather than ceiling.
