SLATE API Selection - Step Accuracy: leaderboard
Long-horizon e-commerce API selection from a thousand-tool library with simulator-verified dependencies. Simulator-verified success rate (%). SLATE v1, hierarchical e-commerce plans, wide distractor tool library. Both native decision model and matched backbone score identical candidate selections through native probability readouts. A step executes only if its prerequisites were selected correctly; task success requires every reference terminal outcome, step accuracy scores allsubsteps. Mean over three option orders; Table4 exact HuggingFace checkpoints/revisions/readout types are pinned. No LLM-judge or mere process-exit proxy.
Metric: Simulator-verified success rate (%). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 12 models tracked.
