CircuitReason-1k: Benchmarking Long-Horizon Visual-to-Symbolic Reasoning in Electrical Circuits
The episode reviews CircuitReason-1k, a benchmark of 1,000 authentic circuit problems testing multimodal models' long-horizon visual-to-symbolic reasoning. Hosts discuss the need to recover topology, build equations, and respect conventions, noting the best model scores 84.8%. They highlight the benchmark's design, including evidence gates, role-separated verification, and diagnostics showing models struggle with dependency depth.
