LLMs embody value systems, and American and European values are not the same (yes, there are overlaps, but also key differences).
More nefariously, I can also imagine LLMs that silently degrade their reasoning when used in a national security context of a non-US country.
So, Mistral may not be competitive with OpenAI and Anthropic, but in many contexts that doesn’t matter. And, perhaps this gap could be closed with more funding (the three billion funding figure is a rounding error next to US labs). I’m sort of surprised that the EU isn’t stepping in to support them.
