Grid Studies Base Models - PowerCodeBench: leaderboard

Grid Studies AppendixC Table 8:519 power-system tasks, native end-to-end score E, original units and equal source protocol. Only standalone no-tool completions are selected from the explicitly labelled base-model sections; base here means no tools, not pretrained checkpoint. Framework/tool-system rows are distinct and not attributed to their backend models. Scores verify required work against deterministic benchmark targets; timing excluded. Metric: End-to-end score E (%).

Metric: End-to-end score E (%). Source: arxiv.org. Saturation forecast: Around 2032. 11 models tracked.
