ResearchClawBench → MCP Atlas

Name: benchgap: LLM benchmark scores, measured and estimated
Creator: benchgap

MCP Atlas is estimated from ResearchClawBench with a Hill curve fitted on 12 models measured on both: y = 0.0000 + (0.8463 − 0.0000)·x^6.00 / (0.13898^6.00 + x^6.00), R² = 0.54, cross-validated error 13.5 pp. It is used for 1 estimate.
