New Fixer-Guided Localization method improves code agent efficiency

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called Fixer-Guided Localization (FGL) to train code localizers more effectively. Instead of solely focusing on the files a patch edits, FGL uses a frozen fixer model to score the likelihood of proposed localizations, guiding the training process without requiring test runs or reinforcement learning. This approach, implemented on Gemma 4 E4B for a Kaggle competition, demonstrated that FGL can help agents find bugs with less code and fewer errors, leading to improved task completion rates and more efficient exploration.

    Let the Fixer Decide: Training a Code Localizer from the Fixer's Likelihood

    Code localizers are usually trained to predict the files a reference patch edits, but the code a fixer needs to read is not the same as the code it changes. We propose Fixer-Guided Localization (FGL): the localizer proposes several localizations, a frozen fixer scores each by how…
