Wes Roth runs Astra for 12.5 hours to build a playable Unreal Engine 3D world

YouTuber Wes Roth posted an in-depth hands-on of Astra, an autonomous agent built on OpenAI models, saying it genuinely "feels like AGI":
- GPT Image → Blender → Unreal Engine pipeline: Astra turns generated images into Blender assets and builds scenes in Unreal Engine;
- 12.5-hour overnight task: from a single Fallout-inspired prompt, Astra produced an explorable, playable 3D world, plus a comic-book alien planet and an Escape from Tarkov-style scene;
- Persistence and multi-machine operation: quota resets, an "AI team" across multiple computers, and lessons distilled into skills;
- Astra also plays RimWorld and Roth plays the game it generated, with notes on safely leaving agents running overnight.
