I really do hope they can catch up with the American models, but I think setting the Chinese models as the goal would be best. They seems to be able to create great models with low cost that are probably useful for 90% of the day to day tasks. Mistral should not focus on competing with Claude Fable or OpenAI's Astra at first but have a good EU alternative to Opus or even Sonnet. The fact that it's European will be enough to be used by a lot of companies and governments in the EU that are (trying to) move away from US tech.
