I Improved 15 LLMs at Coding in One Afternoon. Only the Harness Changed. | Can.ac

In an experiment to improve coding capabilities among 15 LLMs, the focus shifted from model performance to the 'harness' that interfaces with these models. By changing the edit tool within a custom harness, notable improvements in coding success rates were observed. The findings highlighted that harness optimization can lead to significant enhancements in model performance, suggesting that the real challenge lies in how models interact with their environment, rather than solely in model development. The outcomes indicated that better editing formats could enhance various models, resulting in increased efficiency and reduced resource wastage.
