That's not a "promise from Sam Altman", that's a contractual term between Apple, Inc. and OpenAI, LLC.

So I think it's worth as much as Apple is willing to spend enforcing it, which I imagine would be quite a bit.

Even if the promise were made in good faith, I fear it may be hard to resist pressure from law enforcement etc.

That's just the enterprise guarantee. The same applies to Azure OpenAI services and the API services provided by OpenAI directly.

What broken Sam Altman promises are you referring to?

The promise is from Apple, not OpenAI, and likely contractual.

If OpenAI actually went against that, Apple would unleash the mother of all lawsuits.

Tim Cook doesn't seem to mind hanging his reputation on sama's promise, so at least that's something
