> Also, in practice the EU has its deepseek equivalent model in Mistral.

In practice, European companies don’t use Mistral.

First acknowledge the reality, then we can propose solutions.

It is actually not unrealistic to imagine laws for eu gov software only to allow Mistral or Aleph alpha models. They are pretty good - on par with deepseek atleast. There are all kinds of similar requirements already from software stacks to databases.

What I would see even more likely are requirements of no agent commits, use of only human written/vetted code under their name.
