# AA Coding Agent Index — AI model rankings

Artificial Analysis' overall score for coding agents, combining three coding benchmarks with what each run costs and how many tokens it burns. It rates a model paired with a particular agent harness rather than the model alone, so the same model scores differently in different tools. Higher is better.

2 tracked models have a published AA Coding Agent Index score. Higher is better. Scores come from published lab reports and benchmark sources; recorded sources appear beside the scores.
