I don't know if it relates to the same data centers, but this also comes hours after several still recent Grok models were deprecated at short notice. Grok 4.1 Fast is the cheapest way to do research on X (cheaper than the X API!) and it's gone on May 15: https://docs.x.ai/developers/models - freeing up compute to sell?
Unlikely, because xAI had huge amount of overcapacity.
Fuck, I loved grok 4.1, it was a really capable model for the money.
I'd run agents consuming hundreds of millions of tokens for less than a hundred dollars.
