Step-2000 student · 3 Euler steps. Planner: 542 MB across three files, with W8 weights and FP32 computation. Actor: 135 MB, FP32. Physics and inference run in this browser. Desktop Chrome with WebGPU recommended.

Using the built-in model: a few-step distilled student planner with INT8 weights (loads automatically). It is smaller and faster than the paper's planner but may perform worse.

Advanced: use a local full-precision model

The playground runs the built-in quantized model by default. Optionally point this at an exported model folder containing the planner.condition, planner.time and planner.step.gpu ONNX files plus planner_meta.json, then click Apply to switch. Files are read locally in your browser and never uploaded. For the full-precision teacher, also open this page with ?planner=teacher (8 Euler steps).
