Reins harness helps GPT-6.1 Sol control dual-arm robots

Researchers present Reins, a harness that enables off-the-shelf frontier models to operate dual-arm robots on long-horizon, contact-rich manipulation tasks using 3D perception tools and atomic actions. With natural-language prompts and no task-specific code, GPT-6.1 Sol succeeded in 88% of real episodes across five tasks. Without the harness, the model failed every attempt on a shell game and took eight times as long. Open article →
