Benchmarks
Each row is a dated claim by a named party, not a property of the model. A later revision adds a row rather than replacing one. This project publishes no composite or overall score.

|---|---|---|---|
| HumanEval | 63.2 | Vendor reported | November 4, 2023 |
| MMLU | 73 | Vendor reported | November 4, 2023 |
