GR00T 2: Scaling robot foundation models for generalization, dexterity

I'd pay twice as much per token if there was a guarantee they weren't nerfing the model and if it is as good as the original Fable was when it was released. I'm doubtful though. Whatever "tweaks" they've been doing (safety? performance? "saving the best for ourselves") has really taken away the magic for me. I want the LLM magic back.

Are you paying API rates?

I'm pretty confident (from internal evals and monitoring over nearly six months now; across many models) API has never been affected by A/B tests / "nerfs" / etc.

That's interesting, could you share a little more about the evals please? I'm interested in knowing how sensitive they might be to nerfing given in the UI at least the incremental changes can he quite subtle

If they have different "models" depending on if you get it from Bedrock, API from Anthropic, or differing based on which subscription plan you're on, then that's fraud. Disclose the differences.

But FWIW for Fable specifically, I've noticed this via API rates from Anthropic directly. Eg: added cash to my $30/month account to use Fable, and still get obvious nerfing.

But API isn't just twice as much as subscription, is it?
