GPT-5.6 Completes Full 3D Manhattan Modeling in 'One-Shot' Autonomous Run

Developers claim that GPT-5.6 autonomously completed a full 3D Manhattan model in a 'one-shot' manner after running for nearly a week.

This case further demonstrates GPT-5.6's capabilities in long-duration complex agent tasks, sparking discussions in the community about the potential for AI autonomous development.

If true, this will significantly boost developers' confidence in AI's long-term autonomous workflows and promote the adoption of AI-native engineering tools.
