Hah, my first reaction once I saw these random 404 errors was "Maybe it's time to test Claude Code again with the new models" but made a short stop here at HN first, ended up reading your comment.

What other agent harnesses and models (besides local ones) are people enjoying right now that aren't based on platforms that are down currently? :)

OpenCode and Pi. Anything that uses open models, really.

Independence Day > Judgement Day

OpenCode Desktop + Muse Spark 1.3 Free is actually surprisingly good.

GLM 5.3 (usually flash) + OpenCode.

pi.dev + anything else

That makes no sense, they should be able to host chatgpt.com regardless and just say "Sorry, we're at capacity" or something instead of hard 404

Distributed systems are hard. For all we know, this could be the error code returned by some DNS service that is down because of load and a proxy cannot find the records, so 404 makes sense, or whatever. Systems like these don't always have a easy point in the infrastructure that can ALWAYS respond correctly no matter what.

> Distributed systems are hard

... when vibe-coded.

Vibe coded or not, building and running distributed systems is hard :P I think only people who never built and/or ran them would say it isn't hard, regardless of what tools you have available. Not saying OpenAI won't find it extra hard due to their vibe coding, still hard when you're a group of knowledgeable people with/without AI.

Yeah who wrote that website? Oh right

Agreed, it makes no sense to send out 404. Unless some agent finally went rogue with absolute permission and did `rm -rf`

At the very least, should be a 429

exactly - this should be trivial.

Yep, this is most likely it. The shift is fast and enormous.

Maybe only in some regions?

Down for me in SE SA

Providers should surge capacity when another provider fails.
