Open Weights

Kimi K3 Is Free. Running It Takes Eight B300s.

Moonshot released the full 2.8-trillion-parameter Kimi K3 weights on July 26, a 1.56TB download that vLLM will only serve on a node of at least eight B300s. The software gate closed, since Moonshot upstreamed its attention kernel for day-zero vLLM and SGLang support. The hardware bill and a bespoke license are what stop you now.
