model-compose vs Pydantic AI
model-compose: Model-compose is a declarative framework for defining and deploying AI systems using a single YAML file. It enables composition of models, agents, workflows, and tools, allowing deployment locally, in containers, or across distributed environments.; Pydantic AI: Pydantic AI is a Python agent framework for building production-grade Generative AI applications with the ergonomics and type-safety similar to FastAPI. It offers a model-agnostic approach with deep integration into the Pydantic ecosystem, focusing on reliability and developer experience.
