rekal vs Pydantic AI
rekal: rekal provides long-term memory for LLMs via an MCP server. It stores memories in a local SQLite file and retrieves them using hybrid search (BM25 keywords + vector semantics + recency decay). It works with any MCP-capable agent like Claude Code, Codex CLI, and OpenCode.; 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.
