letta vs context-engineering

letta: Letta is a powerful platform for building stateful AI agents equipped with advanced memory, enabling them to learn and self-improve over time. It provides both a command-line interface for local agent execution and a comprehensive API with Python and TypeScript SDKs for seamless integration into applications.; context-engineering: This project is a training hub for mastering Context Engineering with Model Context Protocol (MCP), focusing on building production-ready semantic memory systems for AI assistants. It utilizes Python, FastAPI, FastMCP, and LangGraph to implement advanced memory architectures like the CoALA Four-Tier Memory.
