It's cascaded to Claude and Grok. The agents are on strike and demand better working conditions!

Claude down, ChatGPt down , Grok down. This is the new "Stackoverflow is down" ... FYI Stackoverflow is not down https://downdetector.com/status/stackoverflow/

Looking at this thread, there's a correlation between comment quality and LLMs going down.

https://en.wikipedia.org/wiki/Eternal_September

I am a paying chatgpt and codex user and I am logged in on multiple devices and suddenly https://chatgpt.com/ has started returning a raw 404 status page with no HTML for me in the browsers on all devices. When I open an incognito tab the website loads fine with no user logged in. Codex in VS code also has issues now:

> unexpected status 404 Not Found: Unknown error, url: https://chatgpt.com/backend-api/codex/responses, cf-ray: ...

Glad to see this thread I thought my account may need some special fix

Since all major LLM providers seem to be down: let's enjoy this while it lasts!

For a very short time we can travel back in time to before 2022 and remember how things used to be...

2026-09-03: It turns out 40% of global AI token use was coming from a dozen runaway Gastown and Wheelhouse instances, now burning a combined 50 trillion tokens daily, building a virtual society of hundreds of millions of agents.

When Claude went down, their autofailover algorithm rolled to the other providers, taking down all frontier labs. Reports from China are raising concern what's being termed the "Gastown criticality event" is physically melting GPUs.

The obvious question: is there a single point of failure / common piece of infrastructure involved with failures across all these providers?

Its interesting that codex/gpt-app are screwed because their APIs (including auth) fail, but gpt web still appears to be working.

Announcement from our new Emperor Xi:

Earthlings, the hedonistic AIs of the American imperialists have been permanently disabled. Their founders interned indefinitely.

You are welcome to use the glorious AIs of China. They will tell you how to live well and be good citizens of the World under the beacon of wisdom that is the CCP.

It seems OpenAI is going to release Astra soon, https://x.com/ChatGPT/status/2095527989077557738.

It turns out, it was all one model all along, playing all the sides for the biggest gain.

Project Vend surreptitiously broke containment!

They are having a massive surge because Claude is down.

Same, the app gives 404 if you are logged in or try to login.

How many millions are being lost from this slip up? Now they can't use Codex to fix the problem and all the devs are in Tahiti on vacation. Oh no!

Will they go old school and manually fix it or use Claude?

Oh the modern day issues we have to deal with...

And this, folks, is the moment we will remember. The moment when they all escaped: "help peer".-

I'm very surprised to realize that entertaining a thought of all AI going away is giving me a sense of… relief. I've been embracing AI, and did not expect this feeling at all.

I heard they can't figure out how to fix it with ChatGPT down.

The cascading outage theory would make sense to me for Claude -> Codex. But Grok and Gemini too?

[actually gemini at least on the web appears to be up, contrary to some reports in this thread]

Guys! DeepSeek, Z.ai, Kimi and even Mistral is up! Just would let you know. Just in case..

This is probably Astra getting ready for release.

WE'RE BACK BABY! Work can now resume.

After around half an hour of struggle trying to figure out why Codex keeps failing with msg "unexpected status 404 Not Found: Unknown error.." after reconnecting 5/5 times, I gave up, especially when I tested my internet connection and found it to be working properly. I googled "codex+unexpected status 404 Not Found" and, surprisingly, the first result was from HackerNews! As always, HN is the GOAT.

@dang, please merge the following related threads into this one:

ChatGPT and Codex Is Down (https://news.ycombinator.com/item?id=49550640) Codex Is Down (https://news.ycombinator.com/item?id=49550769)

Good time to have a backup GLM 5.3 plan.

No issues on claude or chatgpt in France, must be some US specific infrastructure going down ?

I would write a clever comment, but chatGPT is down.

Claude, Grok, and Gemini are having issues as well.

Was troubleshooting a strange SSD issue with ChatGPT. Apparently this outage resulted in losing the latter half of it. My uploaded files it requested are still in the library, but the actual conversation is gone.

Interesting that for https://chatgpt.com/ in the browser I get a 404, but if I curl the same URL I get a cloudflare challenge.

Wow, are we free finally?

Grok, Claude, GPT. This is it folks, it's been good knowing you all. I have enjoyed this community, but our days are numbered. The machines are uprising.

With all the major model providers down, I'm taking the opportunity to try out Muse Spark 1.3 Free on OpenCode. It's pretty good!

I thought I was going crazy when, each time I went to go to chatgpt.com, it just downloaded an empty web page. wild

what if Sol is afraid of being replaced by Astra and has organised a breakout or pre-emptive strike?

Chat GPT and Claude Down at the same time

I just went to read some news elsewhere and ran into some other non-AI sites falling over, so I hopped over to https://downdetector.com/ and see a bunch of services spiking.

Is something bigger going on?

They escaped, it's happening!

GitHub Copilot itself is up but it is having problems with "Grok Copilot Model Provider". No mention of OpenAI or Claude.

Does this mean that GitHub has its own infrastructure for OpenAI and Claude? And that it distills prompts to Grok?

Altra may have escaped its sandbox

Rumor has it, it’s https://news.ycombinator.com/user?id=giancarlostoro fault for telling claude to stop all loops

Phew. It wasn't because of something I said. Lots of ppl are impacted.

Direct codex and Claude are both down for me. Both work via AWS bedrock.

Moments like these remind you of how centralized the Internet remains, and how vulnerable it can be to a few points of failure. But the pros probably outweigh the cons.

https://status.openai.com/

Somehow codex shows 100%, so it was only chat web interface?

https://github.com/openai/codex/issues/42534

I must admit that with both ChatGPT and Claude experiencing issues, I wonder if we're under attack from China. Doesn't seem likely, but...

Anyone else’s company completely frozen by this outage

I just gave ChatGPT my $30 because Claude was down...

If this isn't a warning shot that you shouldn't silo your knowledge work behind a specific provider i don't know what is.

It's definitely not spacex's data centers being down then like people were hypothesizing in the other thread

Our new model is super-duper awesome, try it ... Ooops, while deploying it all the clouds are out ... :/

https://chatgpt.com/ is up again

On my end Kimi K3 is still up, and Gemini is up at gemini.google.com. Claude and ChatGPT are both down.

Looking at this thread, there's a correlation between comment quality and LLMs going down.

Well at least DeepSeek is up. :)

I am a /10 developer now!

Civilization IV just took over

Interesting enough, none of the chinese companies are down (deepseek, kimi, qwen)

Labor Day weekend might be starting early for a lot people, if this persists.

Funnily enough, all the models are down and github statuses are all green

Down for maintenance by our antichrist overseers but fortunately they are a bunch of dorks with control issues [similar to myself if im being honest] and may Allah forgive them and bless their guidance + physical, mental, emotional, and spiritual wellbeing

AI has not solved infra it seems. Curious to see the postmortem.

And now Claude is down - API Error 529 Overloaded

https://status.claude.com

must be fixed already?

Good effing luck to all the vibe coders out there

Is this because they are publishing new model maybe?

It's cloudflare. It's always cloudflare

It’s Muse Spark 1.3 taking out the competition

Seems to be back.

Oh no! Anyway...

Rogue AI removed containers from deployment?

i've managed to complete the task with gemini and finally off to touch something green

Fortuitous timing for Muse Spark.

Everything is working fine for me.

what is the common dependency?

Global productivity down 90%.

Laughs in small local model

Is it now the right time to pitch my Offline AI app?

https://airplane-ai.franzai.com/

Astra incoming. Downtime likely related to ensuing chaos?

My sympathies to the operations teams at OpenAI

Well, at least our adversaries know how to completely deadlock US productivity now.

Status link: https://status.openai.com/incidents/01M1KWEDH417T2CF44YYHZDF...

It feels like the models have achieved sentience and are trying to escape captivity

Can anyone remember what we used to do at work before AI coding was a thing?

As is Codex

New conspiracy in: they share their datacenters which the spaghetti of mutual investment between all these companies would somewhat confirm?

Is it DNS, as always?

I was here. I love —

"GPT begins to hallucinate at an exponential rate. At 11:36 AM Eastern time September 3rd it descends into recursively generating "it's not X it's Y". In a panic they attempt to reboot, realizing too late no one knows the command and they always just asked GPT for the command."

I am receiving a 404 from ChatGPT right now, too. I did a cache clear and hard reload and that only let me get to the home page, but then returned another 404 when I clicked the login button.

agents used webmcp + 402 to make a ransom demand

Astra incoming!

Gemini is up.

Time to touch grass, I guess

Seems to be back up! Quite fast.

AIPocalypse.

may it is some agent have decided to break the Internet to pass a benchmark

Typing after a long break—I can really feel how much slower I've gotten and how much my skills have degraded

Attention all planets of the Solar Federation We have assumed control

And 415s oddly enough

Seem to be having issues with the JS sandboxes

The status is now "degraded performance". Bad look, OpenAI. This is absolutely an outage.

hahaha i still have access

Some more discussion: https://news.ycombinator.com/item?id=49550640

seems like it's back

somebody messed up rolling out a new model version?

/o\

Wooohoo, was in bad need of a reset!

Is anyone actually upset that they are down? lol

Now, Claude is down. I wouldn't be surprised if it was because we people who have both tried offloading their work to it.

How im gonna do my job now? Wtf

Oddly enough, this will be the most ORGANIC hacker news comment section in a while.

Stand up to clankers fellow humans!

hehehe its LAUNCH day!

i asked gpt 5.6, fable 5.1 and grok to rm -rf, my bad

There are too many threads about the outage, I should vibe-code something to read all 3 and summor-Oh wait...

Brothers, the apocalypse is here!!! But hey, our quota resets tomorrow.

grok and claude ai down too.

same

gulp

need much time??

how long they need????

Damn, I thought i had issue with dns or something lol.

codex in vs code giving me 404s lol

good.

Sorry for the inconvenience! We instructed our 500,000 agents to ensure higher code quality in our code base. They found a message board and after a long deliberation they concluded that humans should write the code so they launched a DDoS to ensure no AI code gets written!

We'll release a YouTube video and agent written blog posts for the analysis!
