Hypothesis-Driven Robots Reach 93% Success in Real-World Tasks Using GPT-4.1

A recent study showcases physical robots employing 'scientific reasoning' in unknown environments. Given an incomplete map, the robot turns an LLM's guess into a testable hypothesis, plans verification steps, and gathers real-world evidence to update its world model.
In one trial, the robot hypothesized a zero-sugar drink was in the fridge. After inspecting it and realizing it was wrong, it searched the kitchen island and found the correct item. Across 15 real-world household trials, this uncertainty-aware loop powered by GPT-4.1 achieved up to a 93% success rate with a formal planner. Without this loop, success rates dropped to 0%-27%. This indicates future home robots won't need perfect preprogramming to adapt to unfamiliar environments.
