OpenAI's GPT-5.6 Sol Runs Autonomously for 72 Hours to Build a Global Map of AI Infrastructure

OpenAI's flagship GPT-5.6 Sol model has reportedly operated for more than 72 hours without a single follow-up prompt, autonomously assembling one of the most comprehensive maps yet attempted of the physical infrastructure that powers artificial intelligence. The demonstration, shared in mid-July 2026, tasked the model with charting submarine cables, data centers, power plants, substations and electricity grids, guided only by a simple looping instruction: find the largest gap, research it, build it, test it, publish it, and repeat.
