Predibase has launched the first end-to-end platform for reinforcement fine-tuning (RFT), aiming to make advanced model customization accessible to developers and enterprises by overcoming the common obstacle of limited labeled data. Reinforcement fine-tuning allows language models to learn from reward functions, optimizing performance for reasoning tasks and scenarios like code generation and complex reasoning, where traditional supervised fine-tuning falls short. The platform offers a fully-managed, serverless infrastructure that integrates the complete workflow from data to deployment, utilizing techniques such as supervised fine-tuning warm-ups, GRPO, and curriculum learning to enhance model performance. A notable achievement of this platform is its capacity to create specialized models, such as one that significantly outperformed larger models like OpenAI o1 and DeepSeek-R1 in a PyTorch-to-Triton code translation task, all while using fewer resources. The launch includes open-sourcing of the model on Hugging Face and invites developers to explore the platform's capabilities through demos and a webinar.
