Provided that the systems work, they can at least be repurposed to other things. If the organizations that are to train public LLMs can't do it, we can rent the system out to Mistral or something.
So I think something like 5B, starting with 10B to get started, in public money per year, the chip firms are private, some of the LLM firms will be private, but the system is available to train European LLMs-- that's I think a realistic approach.
