Aider is a benchmark for how well a model works as an autonomous coding agent. The official description says: "Aider - coding benchmark based on the Aider coding assistant tool". Below we describe in simple words what benchmarks of this type generally examine.

What does it test?

Aider measures how well a model works as an autonomous coding agent. In detail, it checks:

  • fixing real, open bugs from real software repositories
  • planning multi-step changes, running commands and editing files by itself
  • passing the project's test suite after its changes
  • handling whole repositories, not just small isolated code snippets

How to read the score

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.
