ProgramBench

ProgramBench is a benchmark for how well a model works as an autonomous coding agent. The official description says: "ProgramBench - agentic coding benchmark evaluated with Claude-Code 2.1.156, 200 instances, temp=1.0, top_p=1.0, max_tokens=64000, max_turns=2000, sample_timeout=6h, reasoning_effort=max, 400K context window". Below we describe in simple words what benchmarks of this type generally examine.

ProgramBench 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

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: ProgramBench - agentic coding benchmark evaluated with Claude-Code 2.1.156, 200 instances, temp=1.0, top_p=1.0, max_tokens=64000, max_turns=2000, sample_timeout=6h, reasoning_effort=max, 400K context window. Each instance runs in a (4 CPUs, 8 GB RAM) sandbox with internet access disabled.

What does ProgramBench test?

ProgramBench mainly measures how well a model works as an autonomous coding agent. Concretely, 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.

How is the ProgramBench score calculated?

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better. The declared maximum score of this benchmark is 100.0.
