Foundation Models 1 story

Foundation Models appears within AI Models & Concepts as a focused layer with its own requirements, tradeoffs, and compatibility questions. Coverage uses general-purpose pretrained models, large pretrained AI models, foundation model pretraining, and transfer learning foundation models to explain function, setup, support boundaries, and interactions with the rest of the platform. This keeps Foundation Models narrower than AI Models & Concepts as a whole while giving readers enough context to make configuration or compatibility decisions and recognize when a problem-specific tag is more appropriate.
