How RFT Works

Unlike traditional fine-tuning methods that focus on pattern replication, RFT emphasizes teaching models to reason critically and solve complex problems. The process involves several key steps:

1. Developers provide a task-specific dataset and a grader.
2. The model is trained using reinforcement learning principles.
3. The system rewards successful outcomes and adjusts for mistakes.
4. The model iteratively improves its decision-making strategies 1
