I can help you learn more about Open Source foundation models in Azure Machine Learning.
Open Source foundation models are machine learning models that have been pre-trained on vast amounts of data, and that can be fine-tuned for specific tasks with relatively small amount of domain-specific data. These models serve as a starting point for custom models and accelerate the model building process for a variety of tasks including natural language processing, computer vision, speech and generative AI tasks1.

Model Catalog: Azure Machine Learning studio’s hub for various pre-trained models for language, speech, and vision tasks1.
Model Operations: Discover, evaluate, fine-tune, and deploy models with Azure’s native capabilities, ensuring enterprise-grade security and data governance23.
Model Collections: Access curated open-source models by Azure AI, exclusive Azure OpenAI models, and HuggingFace hub transformers for real-time inference.
Licensing & Preview: Understand third-party licenses and preview terms for models in the catalog before using them for your specific workload.
