GoodBarber's AI Builder Suffers Code Loss After GPT-6 Luna Model Switch

By PulseAugur Editorial · [1 sources] ·

GoodBarber experienced a significant issue with its AI Extension Builder after switching to a new model, GPT-6 Luna, on September 23rd. Customers reported that app changes, which were previously handled with large code outputs, began resulting in drastically smaller code snippets, effectively deleting existing functionality. This occurred because the new model, when asked to write JavaScript, often provided a patch instead of a full rewrite, and the system's validation process did not adequately detect this change. The problem was exacerbated by a retry mechanism that, when a fragment failed validation, would restart from that fragment rather than the entire code base. AI

IMPACT Highlights the critical need for robust validation and change-detection mechanisms in AI-powered development tools to prevent unintended data loss.
