Kimi K3 Open Weights Are LIVE — 2.8T Parameters, Downloadable Today

Moonshot AI released the full Kimi K3 open weights on Hugging Face — the 2.8-trillion-parameter MoE model is now downloadable under a Modified MIT license.

The details:

• Weights: moonshotai/Kimi-K3-MXFP4 (~594 GB MXFP4 quantized)


• Day-0 vLLM support — production inference ready now


• Architecture: Stable LatentMoE — 896 experts, 16 active per forward pass


• Performance: Tops Arena.ai coding benchmarks (1,679 points)


• License: Modified MIT — commercial self-hosting allowed

⚠️ Important caveat: Independent testing found a 51% hallucination rate — K3 excels at structured reasoning (GPQA Diamond: 93.5%) and coding, but free-form generation needs validation pipelines.

Concrete use case — on-prem code review:
Self-hosting on ~18x H100 80GB (~$50/hr reserved) costs ~$0.05/PR review vs ~$5.00 via closed APIs. Breakeven at ~40-50 reviews/day. Data never leaves your infrastructure.
