Has anyone successfully done RL post-training of GPT-oss with meaningful performance gains? What libraries even support it? I guess technically TRL/axolotl, maybe Unsloth... but there are no good examples of doing it...

We are strong believers in open, transparent research, based on our proven track records in medical AI research and building open science online communities. We hope to continue this science-in-the-open approach to research at Sophont to build towards the future of healthcare.

Our vision is to merge highly performant, specialized medical foundation models into a single holistic, highly flexible medical-specific multimodal foundation model. We believe that this should be done open-source for maximum transparency and flexibility

These approaches succumb to the parable of the blind men and the elephant: The blind men are unimodal medical models and the patient is the elephant.

AI is clearly needed to enhance doctors’ ability to provide the best care. However, currently deployed medical AI models are inflexible, rigid, suited for narrow tasks focused on individual data modalities.

Flow matching is closely related to diffusion and rectified flows and Gaussian flow matching is equivalent to denoising diffusion.

Inventors of flow matching have released a comprehensive guide going over the math & code of flow matching! Also covers variants like non-Euclidean & discrete flow matching. A PyTorch library is also released with this guide! This looks like a very good read! 🔥 arxiv: arxiv.org/abs/2412.06264
