Moonshot AI launches world's largest open model with 2.8 trillion parameters

Beijing based startup Moonshot AI has released Kimi K3, a massive model featuring 2.8 trillion parameters. This release positions the model as a significant open weight competitor to top tier proprietary systems currently dominating the market.

Large open models allow enterprise teams to deploy frontier level capabilities on their own infrastructure. This provides a path for organisations to maintain data sovereignty while accessing the reasoning power typically reserved for closed APIs.

  • Kimi K3 is currently the largest open source model available by parameter count
  • The architecture aims to match the performance of leading global frontier models
  • Its availability supports the development of complex AI agents and high scale reasoning applications
