Moonshot has released Kimi K3, an open-weight artificial intelligence model containing 2.8 trillion parameters and a 1 million token context window. The model utilizes Kimi Delta Attention and a latent mixture of experts architecture, ranking third on aggregate benchmarks behind Anthropic’s Claude Fable 5 and OpenAI’s GPT-5.6 while surpassing Claude Opus 4.8.

Priced at $3 per million input tokens and $15 per million output tokens, the model matches the standard tier of rival offerings and extends pressure on Silicon Valley artificial intelligence budgets. Open weights parameters became available this week, with official technical documentation and broader licensing details expected in the coming days. The release continues to narrow the performance gap between open weights systems and closed source frontier models.
