Insurance Agent Benchmark (Cooper Harness): leaderboard

The same 166 Insurance Agent Benchmark cases run through Cooper's production document system — file-type routing, format-specific extraction or rendering, and chunked map-reduce for large files — with the candidate model doing all reading and reduction. Reported beside the model-alone run so the harness contribution stays visible.

Metric: Judge Accuracy (%). Source: www.askcooper.ai. Saturation forecast: Around February 2027. 17 models tracked.
