What is SWE-bench Multilingual?
SWE-bench Multilingual takes the SWE-bench idea beyond Python: the tasks come from real open-source projects in several languages instead of only Python. An agent has to find and fix the described bug so that the repository's tests pass.
What does it test?
SWE-bench Multilingual measures how well a model works as an autonomous coding agent. In detail, it checks:
- bug fixing in different programming languages
- adapting to different build tools and test frameworks
- autonomous navigation of unfamiliar repositories
- correctness proven by each project's own test suite
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.
