Developer creates custom harness to benchmark coding LLMs on personal bugs

By PulseAugur Editorial · [2 sources] ·

A developer has created a Python-based harness to evaluate coding LLMs against a personal corpus of bugs, rather than relying on public benchmarks like SWE-bench. This approach aims to provide more relevant performance metrics by testing models on issues specific to the user's own codebase. The harness is designed to work with any OpenAI-compatible API, allowing for easy integration with both local and hosted models. AI

IMPACT Enables more accurate evaluation of coding LLMs for specific project needs.
