Leaked GPT-6 'Astra' reportedly builds Unity 3D cities, 1.9x faster than GPT-5.6
Dr_Singularity · x · 2026-09-04
An X user shared an unverified description of GPT-6 "Astra": the model allegedly uses Unity to assemble city-scale 3D scenes from existing assets, letting users quickly build explorable immersive environments. Alongside Astra, the Codex harness is said to get a major computer-use speed boost, combining for 1.9x faster task completion versus the current GPT-5.6 Sol.
Caveat: this is third-party relay, not confirmed by OpenAI — treat as a rumor.
