Pydantic AI vs coco-search

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.; coco-search: CocoSearch is a local-first hybrid semantic code search tool that combines vector similarity and keyword matching via RRF fusion. It uses CocoIndex for indexing, Tree-sitter for syntax-aware chunking, and PostgreSQL with pgvector for storage. It supports 32 languages, 9 grammars, dependency graphs, cross-repo search, and multiple interfaces.
