Deft model fixes LLM formulaic writing with Distribution Fine-Tuning

HamelHusain · x · 2026-08-20

Deft is a new model and lab focused on improving AI writing. Its research paper highlights that standard SFT leads to formulaic outputs, overusing certain tokens or phrases ("slop signs").

Deft introduces Distribution Fine-Tuning (DFT), a post-training step that aligns the model's output distribution more closely with the training data. Experiments show DFT improves MMD by 49% and JMQ by 63%. The model significantly boosts creativity, coherence, and clarity, achieving a 100% human-written score on the Pangram detector.
