The facts
Moonshot AI’s official Hugging Face repository now publicly lists the Kimi K3.1 Pro weights; the page displayed about 1.56 terabytes of files and 96 Safetensors shards when checked on 5 November. [1]
The repository history shows an initial commit dated 2 November 2026. That commit record does not establish when the repository or weights became publicly accessible. [2]
DeAI News reported that its live check at about 04:20 UTC on 4 November found no official Kimi K3.1 Pro repository, while Hugging Face now displays a 2 November initial commit. The discrepancy means the public-availability date is not established. [1][7]
The model card describes the model as having 2.8 trillion total parameters, 104 billion active parameters and a 1,048,576-token context window. These specifications are Moonshot’s own. [1]
Kimi’s 23 October launch announcement said weights would be released by 4 November. The Next Web and Beijing News independently reported the earlier commitment; those reports do not independently verify the later upload. [3][4][5]
The posted licence is custom rather than a standard permissive open-source licence. It requires certain Model-as-a-Service providers and affiliates above its stated $20 million aggregate 12-month revenue threshold to obtain a separate agreement before commercial use, and requires prominent Kimi K3.1-Pro attribution for commercial products exceeding its 100 million monthly active user or $20 million monthly revenue thresholds. [6]
Independent benchmark results and evidence of deployment or adoption were not found in the opened sources. [1][4][5][7]
Still unconfirmed
- The date and time when the official repository first became publicly accessible are unknown; Hugging Face displays a 2 November initial commit, while an independent 4 November check reported no official repository.
- Independent performance evaluations and real-world deployment or adoption were not established in the opened sources.

Moonshot AI’s current official Hugging Face repository establishes that the weights are listed by 5 November; the model card and licence are primary records for specifications and terms. The history labels an initial commit 2 November, but DeAI News reported that its direct check at about 04:20 UTC on 4 November found no official repository. That discrepancy is unresolved, so no exact public-release date or deadline-miss claim is made. The Next Web and Beijing News corroborate the earlier promise only. No independent performance or adoption result is claimed.
