What is SWE Atlas - TW?

SWE Atlas - TW is a benchmark for how well a model works as an autonomous coding agent. The official description says: "SWE Atlas TW - agentic coding subtask; mini SWE agent harness, temp=1.0, top_p=0.95, 128K context, avg of 5 runs". Below we describe in simple words what benchmarks of this type generally examine.

What does it test?

SWE Atlas - TW 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.

Official methodology note: SWE Atlas TW - agentic coding subtask; mini SWE agent harness, temp=1.0, top_p=0.95, 128K context, avg of 5 runs.
