GPT-6 Astra early access: dev builds 95% of a flight sim in a single request
Dimillian · x · 2026-09-04
Developer @codestantine shares early impressions of GPT-6 Astra (Ultra mode), claiming its visual understanding and computer use outclass any model he has tried.
Key points:
- He built a flight simulator letting him fly over Tbilisi, with 95% of the game generated in a single Astra request;
- Astra used computer use autonomously to check that historic buildings and monuments looked right from multiple angles;
- It nailed the "fly over my hometown" intent on the first try.
He says he's blown away and can't wait for wider access. Note: early-access anecdote, unverified, not an official release.
