Modified-MIT weights - standard MIT below a 100M-MAU and $20M-monthly-revenue threshold - over a closed corpus, so 3. The Hugging Face API reports moonshotai/Kimi-K3 as neither gated nor private across 96 safetensors shards, so the weights are genuinely open and downloadable, and K3's own LICENSE file carries the Modified-MIT terms: MIT text, with the grant excepted for a licensee's commercial products or services having 'more than 100 million monthly active users, or more than 20 million US dollars' of monthly revenue, plus a prominent-display attribution clause. That is the same instrument K2.6 carries, read directly off K3 rather than assumed to continue from the K2.x line, which is why this reads with high confidence. Only inference and deployment code is published and no corpus is released, so the family lands at open weights rather than open source.

  `"gated":false`, `"private":false`, `license:other` in the repo tags with a LICENSE file in the sibling list, and 96 model-000NN-of-000096.safetensors shards, so the K3 weights shipped and download without a barrier. 1,871,575 downloads in the trailing 30 days; 10,621 likes. No corpus and no training pipeline appear in the tree - only configuration, processor and encoding modules.

• https://huggingface.co/moonshotai/Kimi-K3/blob/main/LICENSE recorded 2026-08-14

  K3's own license file, read directly rather than assumed from K2.x. MIT text with the Modified-MIT carve-out - the grant is excepted where the licensee's commercial products or services have "more than 100 million monthly active users, or more than 20 million US dollars (or equivalent in other currencies)" - and a prominent-display attribution requirement.
