Acá no paramos 💪 Seguimos trabajando con la meta más que clara. 🏴 A que sí, ¿cierto, @belindapop? 🤪 #SomosMéxico 💚
I saw a lot of benchmarks and saying about mythos. Fable spent fours hours trying to convert advanced html/css into a Word document. It has good progress but document was never perfect. Codex solved in ten minutes. I do not have doubts who is smarter, it is not the first time
@IllGerard @UChlab @RamonCo21321719 @freddier No has usado las apps bien. Codex app hace eso y es mucho mas amigable que los cli y sus limitaciones de terminal.
React is a state-based framework, but a lot of people use it like jQuery with JSX. Then AI learned from that code. Now Codex, Claude, etc. happily generate useEffect abuse, duplicated state, ref hacks, and DOM patching. React is not the problem. The mental model is.
@Xxi5olc @awilkinson Might be worth checking the setup/workflow. I’m using 5.5 in Codex and it’s been noticeably faster for me than Claude Code on comparable tasks. What kind of task/repo is taking 25 minutes?
Told a dev to switch from Cursor to Codex with GPT-5.5. He showed me his screen: "I'm already on GPT-5.5 in Cursor. Same thing, right?" Bro. That's not the same thing. The model is the engine. The harness is the entire car. Tool routing, context strategy, agent loops, system prompts — Cursor and Codex differ on every single one. Same GPT-5.5 in different harnesses produces wildly different outcomes. Different cost. Different reliability. Different ceiling. The model is maybe 30% of the actual experience. The harness is the other 70%. How do you explain this to people without sounding like a snob? 😂
@thsottiaux I hope someone rethinks the limits. In this AI era, a weekly reset feels ancient. A 5-hour to 3-day reset window would be far more reasonable.
@matt_gray_ This says less about AI’s leverage and more about how you view people. I’m an AI advocate and use it daily; it helped me go from architecting and coding everything myself to architecting systems and delegating better. But treating human needs as defects is the sick part.
@Luke_Unedited4U @cyrilXBT OpenAI began as research-first, not profit-first. Products changed that, same as the rest of AI. @elonmusk is just being combative here.
@everyonebpup Why is everyone suddenly writing in greentext / 4chan format here? Been seeing it everywhere lately. Write normal please.
@DragonStacker @bridgemindai I agree. And even the frontend/design part is becoming less of a gap. Create a strong mockup with GPT Image 2, then have it implement it. The results can be genuinely professional-grade.
@jasperdevs @TechnikBlogEu @sama Post your prompt and outputs from both, many of us think you are the problem but if show real examples that will probe your point.
Anthropic acting like they’re playing 4D chess while repeatedly shooting themselves in the foot. Claude had the love of developers. They had momentum. They had trust. Then came worse product decisions, unnecessary limits, and self-inflicted damage.
Hey @thsottiaux Would love your thoughts on this, shared some UX feedback for the Codex experience for power users. I think there’s a big opportunity in reducing cognitive load and making context/state much more visible. linkedin.com/posts/danielar…
The hiring process in tech is completely broken. - Round 1: Recruiter screens you for 15 minutes. - Round 2: Technical phone screen. - Round 3: Take-home project. "Should only take 4-6 hours." Takes 20. - Round 4: On-site. 5 back-to-back interviews. - Round 5: "Culture fit" chat with the founder. - Round 6: Reference checks. - Round 7: Waiting. Silence. Ghosted. Meanwhile the guy who got hired knew someone on the team. 6 rounds of interviews defeated by one LinkedIn connection.
@fahmitech @vivoplt The ideal process? Let the people who feel the outcome decide. Too often, engineers are evaluated only by other engineers protecting their comfort zone. Some of the best builders get filtered out not because they lack skill, but because they think faster.
@CaptainInsightX @0xPrajwal_ Did not you say they delivered the SAME thing?
Codex can learn from experience and proactively suggest things it can do for you. It now has an in-app browser, many new plugins, and so much more.
