Asset from the SCALEMED Framework

This model/dataset is an asset released as part of the SCALEMED framework, a project focused on developing scalable and resource-efficient medical AI assistants.

Project Overview

The models, known as DermatoLlama, were trained on versions of the DermaSynth dataset, which was also generated using the SCALEMED pipeline.

For a complete overview of the project, including all related models, datasets, and the source code, please visit our main Hugging Face organization page and GitHub repositories:
