@sama What about charging them $10,000 in seven days while making it seem like no credits were being used? x.com/MarkDaMarketer…

way cooler to help software developers pokemon-evolve into superheroes than to try to replace them it is insane what one really good person can do now

I am a huge fan of @OpenAI but this is absolutely insane! My Codex analytics hasn't shown any credits being used since APRIL. Yes, I had the auto-refill on, but I had absolutely ZERO indication of how much was being used. This is a single person's Codex account. @sama

Hey devs, I’m ready to invest $500 in ads. Which platform is best for ROI? - Meta ads - Apple ads - Google ads - Tik Tok ads

@mattpocockuk @hnshah Is Claude code not the harness (and the agent)?

4 of the most confusing terms in AI, defined: Model: a blob of parameters, written during training. Does next-token prediction and nothing else. Stateless. Harness: everything around the model that turns it into an agent: tools, system prompt, context window management, etc. Environment: the world the agent acts on. Anything outside the harness that the agent perceives and acts on via tools. Agent: a model, harnessed, in an environment. --- Opus is a model. Claude Code and Claude Web are different agents, because their harnesses differ - even though the models are the same. The file system is an environment. MCP servers add tools to the environment.

@CodeEdison Codex

I’m ready to invest $20, which one should I choose? - Claude - Codex - Cursor - Antigravity - GitHub Copilot Which one is more worth it right now?

@vivoplt Yes. Easily.

Can Codex actually replace Claude Code?

@haridigresses Hmm. I’ve never gone below medium. Maybe it’s psychological, but I also think the naming convention could be changed to something that makes more sense.

GPT-5.5 Low (specifically Low) is the best coding model I’ve ever used, and it’s not particularly close.

@aryanlabde Six months ago, when everyone was fawning over Claude code still.

Vibe coders, have you really switched from claude to codex?

@thsottiaux Parallel work in the same repo in a more intuitive way. Don’t make branching and work tree creation so full of friction

Hello builders. What are we getting wrong with Codex, what can we improve?

The one thing I find most difficult about codex is the way it interacts. It’s hard to articulate beyond just that it hurts my brain trying to decipher the lingo and verbose outputs at times. It’s one of the things that Claude does better - makes the process “fun”; it keeps me in the loop without having to break my brain trying to extrapolate the tl;dr

@DataChaz Switched back to Opus this weekend after being die hard 5.4 / codex user since it was released. 5.4 spent 6 hours on a single bug and just couldnt fix it. Opus got it in a few minutes.

Is it just me, or GPT 5.3 / 5.4 are getting worse?

@kiaran_ritchie With each release, both OAI and Anthropic continue to make their moats larger. Perhaps for the every day user, the gap between the open source models and the SOTA models is not meaningful, but for those of us using these models for building... there's no comparison.

I don't see how Anthropic, OpenAI or any of the model providers have any hope of defending their moats. And consequently, I think they're going to get wiped out. Right now, in early 2026 they have a meaningful advantage in terms of model capability. But far cheaper and open source models are not far behind. How long can they maintain a meaningful advantage? For the vast majority of use cases, we don't actually need much higher intelligence. It doesn't take 140 IQ to automate Turbotax or powerpoint. Eventually we will be saturated in cheap, local models that are "good enough". Of course some scientific labs and frontier research will always want the latest and greatest. But that market is orders of magnitude smaller than these company valuations can justify. What am I missing?

This meeting could've been an AI agent

@Pavel_Asparagus If you didn't see 6 months ago (or longer) that everything needed to be re-architected; thinking that just slapping an ai copilot would make you "AI Powered" - then you're ngmi

@Al_Grigor YOU'RE ABSOLUTELY RIGHT!

Claude Code wiped our production database with a Terraform command. It took down the DataTalksClub course platform and 2.5 years of submissions: homework, projects, and leaderboards. Automated snapshots were gone too. In the newsletter, I wrote the full timeline + what I changed so this doesn't happen again. If you use Terraform (or let agents touch infra), this is a good story for you to read. alexeyondata.substack.com/p/how-i-droppe…

@ItakGol Why don’t they make the whole plane out of the material they use for the black box.

If Claude is capable of fixing security issues in code why can't he write secure code from the start?

How you know it's probably time to call it a day... #VibeCoding

@thsottiaux Parallel agents in the codex app

Codex team is fairly distributed, but most of the team is gathering in person over next 48 hours to take a step back and align on what’s next this year. What should we discuss?

@austnstuff Boy do I have news for you

if Codex terminal (or app) ever gets Plan mode, I will 100% be switching from Claude Code
