[r/LocalLLaMA] I compared 8 AI coding models on the same real-world feature in an open-source TypeScript project. Here are the results

Summary

This report compares eight AI coding models on a real-world TypeScript project, highlighting the limitations of synthetic benchmarks for evaluating practical coding assistance. It assesses models based on their ability to integrate new features into an existing codebase, rather than just solving isolated problems. The findings indicate that inexpensive open-source models, particularly from China, are approaching competitive performance levels.
