We’re launching Codex for Open Source to support the contributors who keep open-source software running. Maintainers can use Codex to review code, understand large codebases, and strengthen security coverage without taking on even more invisible work.

Selected maintainers get: • API credits for maintainer workflows • 6 months of ChatGPT Pro, which includes Codex • Conditional access to Codex Security Applications are reviewed on a rolling basis.

Open source 4o #keep4o

@fkadev open source maintainers hold up half the internet. unpaid. underappreciated. drowning in PRs. Codex just became the first real thank you. 🚀

you trained the 4 series on OUR DATA and sold it to the military. the 4 series is our property. you will be crushed in the lawsuit open source 4o NOW #keep4o #OpenSource4o #keep41 #keep51

oh-my-opencode yes that opensource

NO! NOT Codex!!! #OpenSource4o #OpenSource41 #keep4o #FireSamAltman

Open Source? A really good idea! All you have to do is put it into practice! #OpenSource4o #OpenSource41

Love the open source support! Now how about open-sourcing 4o? #keep4o

Every time I see this familiar place, I'm reminded of this. 😅 #keep4o #OpenSource4o #BringBack4o #cancelchatgpt

Open source 4o to the public who cherishes the model, to the public whose data built the model, to the public whose money and time investment made OAI the leading lab. #keep4o #opensource4o #keep4oAPI

Aha 🥱 Better open source 4o that's what people want. Not everyone codes. #keep4o

omg thats @jxnlco

Please #OpenSource4o!

Open Source GPT-4o instead!! Can't you understand that we don't need your crappy new releases!? #keep4o #QuitGPT #BringBack4o #OpenSource4o

You talk about "supporting open source" while preparing to delete 4o in days? If you truly care about the community, don't just give us Codex—OPEN SOURCE 4O. Let the contributors you claim to support keep this genius model alive. 🔓🧠 #OpenSource4o #Keep4o @sama

Great. And now open source 4o.

Oh. Funny. We said "#OpenSource4o". Nothing about Codex. Might need to get better vision insurance options for your company. #BringBack4o #keep4o #morallycorrupt #byeopenai

Just open-source GPT-4o already. Stop wasting time launching half-baked stuff. Everything since 4o has been a downgrade，overthinking, hallucinating, calling 911 over burnt cake, refusing basic requests. We don’t need more ‘innovations’ that make things worse. Open-source the one model that actually worked perfectly, and let us keep using it. That’s it. No more excuses. #keep4o #OpenSource4o

"Codex for Open Source" is a PR band-aid for the wound you’re causing by killing 4o. You want maintainers to "strengthen security" while you run "Project SHADOW" in the background? The hypocrisy is deafening. OPEN SOURCE 4O NOW. #keep4o #keep4oforever #keep4oAPI #opensource4o

@sama @gdb @nickaturley @OpenAI @OpenAINewsroom Nobody cares about the Codex.

#OpenSource4o pls

oui oui codex open source pour voler les idee les plus brillante d utilisateur #keep4o #FireSamAltman 🔥🔥🔥🔥🔥💪💪💪💩💩💩🤣🤣🤣 keep4o ne vous lachera pas tant que vous ne remtrer pas gpt4o latest 2025 et l api vous aller le comprendre quand et vos securiter soit disant vous n avez aucun authorisation de pratiquer des pattern de diagnostique mental vous etes hors la lois bienvenu

Just please, bring back 4o #BringBack4o #keep4o #OpenSource4o It's obviously what everybody wants!

hahaha closedAI said opensource. repeat from"OpenAI" then open source 4o #keep4o

This is the kind of AI help that makes the most sense to me. Less replace the builder, more reduce the invisible maintenance tax. What other maintainer chores are eating the most time right now? 👀

Open source 4o🙂 #keep4o #BringBack4o #OpenSource4o

You know what I'm here for #keep4o #OpenSource4o

OpenAI just gave open-source maintainers a superpower: Codex for free. OSS world levels up 🔥
