Show-Harness: Can Small VLMs Replace Frontier Models in Robot Control?
Can a small vision-language model take over robot control from a frontier agent? This episode explains what Show-Harness actually compresses, how its semantic action interface works, and where its strongest results come from. We cover three central questions: why a compact movement vocabulary changes the learning problem, how GUMI turns browser-based demonstrations into policy-training examples, and what the real-robot evaluation establishes. The method combines supervised action imitation with LoRA adaptation of Qwen3.5-2B, using demonstrations from Franka and AgileX robots alongside a…
