I'm joining @OpenAI at the end of the month, and I can't wait to get started! I'll be working on everything related to Codex, bringing what I learned building Codex Monitor, and working with the developer experience team with @romainhuet!

i asked GPT-6.1 Terra to show me its computer use alongside Sol. here’s my prompt: “I need you to find a long but generic form on the internet and record my screen while GPT-6.1 Terra fills it out in Fast mode. Then have GPT-6.1 Sol fill out the same form in Fast mode and show both recordings side by side." in the original run of the same form: Terra took 53.5 seconds vs 3:21.7 for Sol. that’s a 2:28.2 difference! that run used accessibility controls, which computer use normally defaults to) the recorded video uses mouse controls so you can see the cursor.

I truly enjoy working on my own project with agents. I have 1000+ commits on Dark Veil. I can just push to main. Create worktree/PR when I want a bit longer work/check etc.. but it just work. No complex agentic loop or process. Just idea to prompt to test to ship.

To be fair we already had a good iPad layout, so all it took what to get our sidebar layout reworked a little bit! More to come for the Duo + ChatGPT/Codex!

these blocks are mostly accidental and a result of difficult decision boundaries; there is no prohibition against reverse engineering with codex. it's getting fixed

You'll soon be able to really make you build unique in Dark Veil, leveling up will allow you to assign stats before the shop! I'm trying to make the UX as simple and fast as possible.

??? Eurostar is probably the only train to randomly put train earlier. This is actually inconvenient.

New unique sigil: Aegis. Create a projectile barrier when you dash. Also asked Codex to setup card + preview of the effect so I can get consistent with sigil implementation and testing.

Honestly, having a ton of fun making and playing this game. I keep adding more and more “keywords," and everything is keyword-based. You can enhance everything with sigils, mix and match stuff. A lot of emergent properties come out of that. Thousands of combinations already.
Yes you can play football in the game now
