Moonshot AI

Chinese frontier lab behind the Kimi assistant and Kimi K3 open-weight MoE.

Moonshot AI builds the Kimi product family and releases large open-weight models. Kimi K3 (2.8T MoE, 1M context) is its flagship open multimodal agentic release under the Kimi K3 License, with API access at platform.kimi.ai and hosted access on Databricks Unity AI Gateway (2026-08-06).

Why Moonshot AI matters

Kimi K3 pushed open weights into the 3T-class MoE tier with competitive agentic coding and multimodal scores. Teams evaluating self-host frontier models need to weigh capability against the custom license’s commercial clauses.
