The Coding Agent Pushed the Alphabet
A coding loop solved Push-T without demonstrations, then extended its generated simulator curriculum from A through Z.
Summary
A coding loop solved Push-T without demonstrations, then extended its generated simulator curriculum from A through Z.
For the classic Push-T benchmark, an LLM coding agent searched for the simulation, experimented with push mechanics and iteratively wrote a policy. The authors report 100 percent simulated success with 46 percent fewer steps than a diffusion policy trained on 200 demonstrations, then extend the method to alphabet-shaped blocks and two simulated robot arms. Videos and fuller details were still promised, so the striking claims remain an early short-paper result rather than independent verification.
