Parsimony: Open-source benchmark measuring code added by AI models

Parsimony is a new open-source benchmark that evaluates how much code AI models add by counting syntax elements, addressing long-term codebase maintainability. It builds on existing benchmarks by penalizing excess code, which can complicate future development.

Parsimony is a new open-source benchmark that evaluates how much code AI models add by counting syntax elements, addressing long-term codebase maintainability. It builds on existing benchmarks by penalizing excess code, which can complicate future development.

AI-assisted summary based on the listed source.

Existing benchmarks measure solve rate and token output/cost, but don't punish excess code, which makes a codebase harder to work with in the long term. I wanted to measure this since it matters most for long-term projects. Method: it takes the patches that benchmarks already publish (DeepSWE, SWE-bench Verified,...

Measuring code bloat helps developers understand the maintainability impact of AI-generated code, crucial for long-term projects. This benchmark offers a more nuanced evaluation beyond solve rate and token cost.

Hardware and robotics watchers may want to track whether this becomes a product, benchmark, or deployment signal.
