FunCAD - Full harness: leaderboard
FunCAD (2026): 46 functional CAD tasks, one independent attempt per task family within three hours active time, ReAct construction with the named support condition; constructors use Codex GPT-6 Astra High and Cursor Grok 4.6 extra-high. Separate final evaluation uses GPT-6 Astra medium reasoning and one-million-token context to bind physical requirements to simulation tests. Grok history/multiple attempts are a separate experiment. Tasks Solved (of 46); higher is better.
Metric: Tasks Solved (of 46). Source: arxiv.org. Saturation forecast: Around 2028. 2 models tracked.
