OpenAI: AI News Week Ending 05/29/2026

Image created with gemini-3.1-flash-image-preview with claude-opus-4.7. Image prompt: A Byzantine gold-ground mosaic apse featuring a single centered iconic six-petal aperture-flower of hammered gold with a deep imperial-purple pupil, encircled by a halo of fine silver circuit-rings and a slow gyre of tiny clockwork songbirds, tesserae texture with visible grout and warm candlelit glow, the words OPENAI set in bold ivory Trajan Roman capitals across the lower third, opulent burnished gold and Tyrian crimson palette, painterly tactile render, 16:9 full-bleed.

Another one: today we released Remote Computer Use in Codex! This means you can use all the apps on your Mac from Codex Mobile, even when your computer is at home and locked. It’s kinda magic.

so Codex on iPad acts like a Codex mobile phone, which gives you the full desktop UI/UX. meaning, you can use your iPad to control your mac mini at home and have full screen portable development, it’s really magical.

Economic Futures in the Age of AI

very belated but in retrospect i think @sama’s mythical “”build a business that gets better when models get better”” is basically what I called Agent Labs here. seeing a very direct correlation with model performance and agent lab revenue, discontinuity in Q4 2025 (clip from

For complicated agent work, it’s amazing how much GPT5.5 has improved. I found 5.2 to be very far behind Opus. Now using Opus 4.7 after 5.5 feels like a big step backwards. Gotta love this level of competion! Strong comeback for OpenAI.

Huge credit to the OAI team for solving the unit distance problem with 5.5 – it is now my go to example that models can in fact pull together disparate ideas into new discoveries. As with all 4 minute miles, we had to try and cross it too! Turns out mythos solves it with a cute,

37 minutes to eat my entire token budget with a task that used <1% on Codex, and the output so far is somehow worse than Codex. Maybe I do not like ultracode.

At @ThriveHoldings, we built a product with @OpenAI to automate tax prep for the 30+ accounting firms we own across the country. This season, it processed 7k+ returns. But what I think is more interesting is that the product meaningfully self-improved as accountants used it.

GPT 5.5 found a 27-year-old RCE introduced in April of 1999. I’ve triple-checked the flow and commit history, it’s real. Can’t wait to responsibly disclose!

GPT-5.5 Pro is a very solid fact checker. I can throw entire chapters at it and it will hunt down every key reference accurately. The only real annoyance is that it loves nuance, so returns a lot of “the general idea is right, but you are not taking into account tiny detail X”

I found this Wired article on AI fact-checking frustrating. It could have been about why we continue to need human fact checkers (talk to people, use judgement, resolve conflict). Instead it is full of old info & stuff about free models GPT-5.5 Pro checked it (& I checked GPT)

I redid the multi-digit multiplication experiment, now with gpt-5.5. With medium reasoning and 7 samples each cell, it pretty much aced the test with 99.46% accuracy. The model had no tools to call and had to rely on its reasoning. Can it go further? (1/4)

If you know one thing about every right now, it’s that we’re heavily Codex pilled. So we wrote a guide on how to use Codex for knowledge work as well as we do. You dont want to miss this one…

It took me like 2 months, but I’ve grown to love gpt-5.5. You have to prompt entirely different and put some time into your agents[.]md. Now that I’m over the hump, I can’t really use any other model for code.

Over the last 4 days I’ve probably spent 3+ hours trying to work around weird bugs and limitations of the remote features in the Codex app. I’m trying to give them all the feedback they need to fix it. Did not expect the experience to be 10x smoother in our open source app 🙃

Seems GPT-5.2 reaches expert level in peer review: 45 scientists took 469 hours evaluating human & AI reviews on 82 papers. “”Surprisingly, current AI reviewers are competitive even with the top-rated reviewers in Nature’s official peer review…”” though not without weaknesses.

Still limited by compute, so I built a thing that runs codex in the cloud, powered by @Cloudflare firecracker boxes (and since that’s not beefy enough for larger projects, tests are run via crabbox) Uses Ghostty ofc, via WebAssembly. Codex replicated itself, basically.

The wild part of Codex sub-agents isn’t that one AI can use Chrome. It’s watching a single prompt turn into seven browser sessions running at the same time. Flights, cars, Airbnbs, hikes, forms, checkout pages. Still rough around the edges but still feels like the future
