Mistral and Kimi expand self-hosting, with different commercial licence boundaries

Its weights are downloadable, supporting deployment independently of Mistral’s API. Kimi K3.1 Pro’s repository also contains weight shards; its history begins November 2. That establishes a new artifact to inspect after October’s hosted launch, without proving the exact hour or day the repository became public. [1][2][5][7][8]

The licence difference matters to business design. Subject to its exemptions, Mistral requires a separate commercial licence before commercial use if the licensee or any affiliate operates a Model-as-a-Service business. Its definition excludes model capabilities embedded solely inside specific end-user features or harnesses, and simple relaying to another host. There is no revenue threshold in this condition. Section 3 exempts internal use that does not make the model or its derivatives available to third parties, and any use through Mistral’s official products. [3]

Kimi uses a similar service definition but adds a threshold: when the licensee or an affiliate operates such a business and their aggregate revenue exceeds US$20 million over any consecutive twelve months, commercial use requires a separate agreement. That is total group revenue, not revenue earned only by serving Kimi. Internal use and access through Moonshot’s official products or certified inference partners have explicit exemptions. [6]
