Elevated error rates on Opus 4.5

Argh went down right in the middle of me solving the Riemanm Hypothesis. If they claim AGI … I’ll take my million dollars! :)

I'm very curious about what's going on there. It's been in a "Major Outage" for over two hours now, with a previous fix rollout apparently not helping matters. I wonder if it has to do with the recent rollout of Cowork.

Will be looking forward to the postmortem.

Kinda sad because I thought of a great, practical use of Cowork to demo to the company today to demonstrate how useful I thought it could be across a range of user types. Such is life.

That's actually a great ad for why you can't depend on such tools :)

Seems like its not just Opus but Sonnet as well. Might be related to Cowork gaining popularity?

So, what are you guys doing while waiting for your code agents to continue their work?

It's the new "my code is compiling" - "my agents are developing the feature"

So what's the best alternative to Opus today?

Touching grass.

For code? There's Gemini 3 Pro and GPT 5.2.

(in my experience, for my C#/TypeScript usecases, Opus 4.5 still ahead inside VSCode Copilot because it is more obedient with regards to tool calling).
