Kimi K3 Weights Now Free to Download — World's Largest Open-Weight Model Goes Public
One-liner: Moonshot AI dropped the full Kimi K3 weights on Hugging Face on July 26, giving any researcher or company free access to the world's largest open-weight model.
Key Facts
- 2.8 trillion-parameter Mixture-of-Experts model; 16 of 896 expert sub-networks activate per token
- 1-million-token context window; MXFP4 weight quantization brings total storage to ~1.4 TB across 96 Hugging Face shards
- Together AI and Modal offered day-0 cloud hosting access
- Distinct from the July 19 coding-benchmark announcement — this is the actual weight files made free to download
Why It Matters
The biggest publicly downloadable AI model in history is now freely available — no API fees, no usage caps. For enterprises and researchers who need full model control, air-gapped deployment, or simply want to avoid vendor lock-in, Kimi K3 sets a new baseline for what open-weight compute can deliver.
