I've noticed something else - as Anthropic models get even more and more superhuman, they seem to serve me more and more casual nonsense.

Not like adding glue to pizza. Here's an example from today (paraphrasing): "you need to run `git merge-base branch1 branch2`. Pay attention to the order of arguments, it is important: `git merge-base` is symmetric and returns the same value regardless of the order of inputs".

So which one is it? Symmetric or not? It's not even one of those where it self-corrects, it just happily contradicts itself halfway through the sentence.

My pet theory is that these frontier models do quite a bit of brute force at the end - some kind of beam search - and silently downgrade you depending on demand or compute availability.

Still not great. This particular nugget is from Sonnet 5, default settings.

Incident is claimed to be resolved but I'm now (11:22 UTC) getting:

   API Error: 529 Overloaded. This is a server-side issue, usually temporary — try again in a moment. If it persists, check https://status.claude.com.
And the status page says all green.

Update 11:27 UTC: I saw the error first at 11:22 UTC. Retry at 11:27 UTC still failing. Status page is still green.

Update 11:28 UTC: Incident has been declared dated 11:27 UTC https://status.claude.com/incidents/mfdtrknpxghq

So, how's the OpenAI situation? Is the grass greener on the other side?

Déjà vu.

Claude decided to take an extra day off, after going on vacation yesterday [0] and when Codex went and took a longer break the day before that.

No wonder the amount of water that both Claude and Codex are taking they also need so many frequent hydration breaks.
