I am curious about the claim that the subscription models are different. Has anyone benchmarked this?

maybe he meant about server-side features? otherwise its dumb. OAI and Anthropic are using azure/aws/gcp...

How does that work? Doesn't that mean Microsoft/Amazon/Google have full de facto access to OAI's and Anthropic's model weights and operational processes?

This is one reason it surprised me that Anthropic decided to run stuff on Musk's hardware. It seems overwhelmingly likely that the new Grok release is informed by what Musk has been able to learn from that relationship.
