Claude Status: Elevated Errors Hit Multiple Models
Elevated Errors for Multiple Models
Anthropic is investigating elevated errors affecting requests to Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5. The incident impacts claude.ai, the Claude API (api.anthropic.com), Claude Code, and Claude Cowork. The status page reports the issue was posted at 13:26 UTC, with updates to follow.
We are investigating elevated errors on requests to Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5.

A nice chance to try sonnet again, must say, I'm not missing the load bearing assumptions, honest read of the permission matrix, what's genuinely a Django convention and what's a design choice, what's worth my thinking, and what's worth being precise about.
Long story short, it seems to be faster and less vocal but not much dumber (it's just my thinking partner, so I read a lot of the output as I create a large data model).

Codex seems to also be down for some folks (me included) https://www.reddit.com/r/codex/comments/1w69ff6/whats_this_e...
Their status page is hard to believe given how many folks are chiming in to report on Reddit https://status.openai.com/

Grok models are struggling too: https://status.x.ai/

Looks like trouble in the SpaceX datacenters.

The interesting thing is they changed default mode for Claude code to auto mode and auto mode uses sonnet to decide whether the command is safe or not. With their Sonnet model outage, the entire thing stopped working.
here is the error it was throwing:
> Error: claude-sonnet-5[1m] is temporarily unavailable (overloaded), so auto mode cannot determine the safety of Edit right now. Wait a moment and then try this action again. If it keeps failing, continue with other tasks that don't require this action and come back to it later. Note: reading files, searching code, and other read-only operations do not require the classifier and can still be used.

Demand > supply. It's impressive that customers have not migrated en masse to other providers, given the frequency of these outages. Perhaps switching costs are greater than some would believe. Or, qualitative differences between models continue to exist, despite matching on public benchmarks.

The competition for the least reliable developer service continues between GitHub.com and Claude.com...

It would be really funny if Anthropic engs run open weight models locally when they need to fix Claude API issues :)

Setting aside annoyance at the downtime, I'm really curious about the reasons for the failures, because I have to imagine there are some novel failure modes when serving these giant models that I haven't experienced with the kind of work I've done.
Anyone out there working in this space who can elucidate us on interesting failure scenarios unique to the space?
