SWE-bench_Lite_Agentic#

Overview#

SWE-bench Lite Agentic is the agentic-mode evaluation of SWE-bench Lite, a focused subset of SWE-bench containing 300 Issue-Pull Request pairs from 11 popular Python repositories. The model autonomously drives a multi-turn agent loop inside a per-instance Docker container to resolve real-world GitHub issues.

Task Description#

Task Type: Automated Software Engineering / Bug Fixing (Agentic)
Input: GitHub issue description (no oracle file context)
Output: Code patch (diff format) collected from git diff after autonomous editing
Size: 300 carefully selected test instances

Key Features#

300 test Issue-Pull Request pairs
11 popular Python repositories covered
Real-world bugs with verified solutions
Multi-turn agent loop with per-instance Docker sandbox
More manageable than full SWE-bench while still challenging

Evaluation Notes#

Requires pip install swebench==4.1.0 before evaluation
Docker images are built/pulled automatically for each repository
See the usage documentation for detailed setup instructions
Popular benchmark variant for initial agentic model comparison

Agentic Mode#

This benchmark drives a multi-turn agent loop (mirrors mini-swe-agent’s swebench.yaml) inside a per-instance SWE-bench Docker container. The model issues bash commands to explore /testbed, edit source files, and finally submits its git diff patch by printing the sentinel COMPLETE_TASK_AND_SUBMIT_FINAL_OUTPUT followed by the patch contents.

extra_params.action_protocol selects between:

toolcall (default): OpenAI function-calling protocol with a single bash tool. Recommended for any model that supports tool calling.
backticks: text-based fallback expecting one ```mswea_bash_command ``` block per turn. For models without function-calling support.
