Developer @TokenGremlin claims a rumored OpenAI model, GPT-6.1 Sol, has been autonomously iterating on a project in Ultra mode for more than 16 hours — using Blender and Three.js, running entirely in the browser, and still in progress at posting time.

He describes the model as "extremely capable, surprisingly cheap, and now fast enough to make long-running agentic workflows practical." The rebroadcaster's takeaway: the real flex isn't the demo, it's an agent that keeps working after you go to sleep.
