What happened and what to do
Published on June 15, 2026, the paper investigates why supervised fine-tuning (SFT) can help smaller networks yet have inconsistent or harmful effects in language models. Its analysis uses changes in token interactions to explain these effects and may help engineers understand SFT behavior and decide when to stop training.
In practice, a company could implement staged training evaluations, track changes in model behavior, and define criteria for continuing, adjusting, or stopping SFT. This makes it possible to compare results against evaluation tasks and data relevant to the intended use, without assuming that more training always improves a model.
How the consultancy can help
Wendelmaques can diagnose your fine-tuning and evaluation process, define metrics and stopping criteria, and implement monitoring and evaluation pipelines on your infrastructure. The scope can also include ongoing operation of these processes.
