They don't need a rebrand, they need usable models, they already have the best branding in the industry, but right now there is open-source models with open weights and favorable license that is above them, why don't they fine-tune and incorporate those models?
Because France wants to be sovereign ?
Why would France not be sovereign, the license is Apache2, that's the whole point, they can take the model and rebrand it as Mistral and incorporate it as part of their model list?
