CFEval

CFEval is a benchmark for how well a model works as an autonomous coding agent. The official description says: "CFEval - Qwen's CodeForces-style competitive programming evaluation; score is an Elo-like rating (higher is better)". Below we describe in simple words what benchmarks of this type generally examine.

CFEval 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 an Elo rating, built from head-to-head comparisons between models (like chess ratings). The number is only meaningful relative to the other rated models — higher is better.

Official methodology note: CFEval - Qwen's CodeForces-style competitive programming evaluation; score is an Elo-like rating (higher is better).

What is the CFEval benchmark?

CFEval is a benchmark for how well a model works as an autonomous coding agent. The official description says: 'CFEval - Qwen's CodeForces-style competitive programming evaluation; score is an Elo-like rating (higher is better)'. Below we describe in simple words what benchmarks of this type generally examine.

What does CFEval test?

CFEval 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 CFEval score calculated?

The score is an Elo rating, built from head-to-head comparisons between models (like chess ratings). The number is only meaningful relative to the other rated models — higher is better.
