OK, I guess my confusion was that the effort to ban open weights models is what I would categorize as "groveling at the white house to try to stop their competition".

Google has produced Gemini Pro, Meta produced llama3-70B/llama3-405B and now has Muse, Musk has Grok. These are very capable models and to claim that they are not frontier is to stretch the meaning unless you want to say "#1 model" Gemini Pro at one point even if for a week, was #1 model.

Musk didn’t sign it.

nVidia did and they released good models – same with Meta, Microsoft, IBM, Mistral – all are signatories.
