What are the top 1 models on AA Coding Agent Index?

1. GPT-6 Astra (OpenAI) — 67.

How many models have a published AA Coding Agent Index score?

1 tracked model has a published AA Coding Agent Index score. Scores are the figures reported by each lab at that model's release, so this page is a record of results over time rather than a re-run leaderboard.

Agentic coding

AA Coding Agent Index

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.
