OpenAI has rolled out Reinforcement Fine-Tuning (RFT) for its o1 models, sparking excitement in tech circles this December 2024. RFT lets AI learn by reasoning from feedback, cutting down training examples needed—perfect for sectors like healthcare and law. Notably, the o1 Mini with Thomson Reuters hit 45% accuracy in gene ID tasks. Early access is open now, gearing up for a 2025 launch. Just remember, good data is key, or RFT might throw a subjective tantrum!
