It already powers Composer training across tens of thousands of GPUs. Is it deployable Yes,…

Mistral is having a moment. With access to less funding and fewer compute resources than OpenAI and Anthropic, the French AI lab has lagged behind its American rivals in model performance. But recent turmoil stateside has created a window of opportunity. In June, the Trump administration placed restrictions on the distribution of models from Anthropic…
