Dev Rebuilds AGI City With Hundreds of Parallel Agents in 18 Hours on GPT-6
D3VAUX · x · 2026-09-06
Developer D3VAUX released a playable demo of "AGI City," originally built with Codex and successively overhauled through GPT-5.5, GPT-5.6 Sol, and now GPT-6 Astra. Over 18 hours, he spun up hundreds of agents to rethink, rebuild, and polish the project. All visual assets are AI-generated with GPT post-processing; audio is partly self-composed, partly generative. Playable demo available.
