Google DeepMind researchers have discovered that Supervised Fine-Tuning (SFT) is the primary driver of safety properties in their Gemini models, rather than other training stages like Reinforcement Learning (RL). Experiments comparing pre-training-only versions of Gemini 3.1 Pro and Gemini 3 Flash with SFT to their production counterparts showed remarkably similar safety performance. This finding suggests that SFT is a high-leverage intervention point for improving model safety and behavior in future Gemini developments. AI
