CircuitReason-1k - Direct Reasoning: leaderboard
The 239 direct, single-step problems of CircuitReason-1k (2026), grouped by the length of the dependent chain from diagram evidence to the final physical answer. Accuracy in percent, every requested output must be correct; higher is better.
Metric: Accuracy (%; exact problem-level correctness on the 239 direct (single-step) problems of CircuitReason-1k's authentic textbook circuit problems; typed deterministic scoring for 585 problems and identity-blinded, reference-assisted multi-model judge consensus (strict majority of at least three votes) for the other 415; every requested output must be correct; missing, failed or unresolved answers count as wrong; image and question only, no output-token cap, open models in their native thinking mode).
