Claude Opus 5 tops EEBench, where circuits are graded by physics
A new benchmark grades AI-generated circuits the way hardware is actually graded — in a simulator, against real datasheets, at every tolerance corner. The early results are better than anyone expected and nowhere near good enough. OpenAI put a printed circuit board in a GPT-6 Astra demo, and the team behind atopile answered with the missing half: EEBench, a benchmark that hands models real electrical engineering tasks and then grades the result by running it through SPICE against components pul
