I don't think the claims about capability are ridiculous. The idea that the general capability is proprietary and that it will be exclusive to the trusted partners of one company is ridiculous.
Will it? All the big companies are invested in AI anyway; the people getting exclusive access to this are going to be under an NDA anyway.
It will leak eventually, but the news that is isn't much better than current models news may not be enough to dispel the original claims.
