Memory Blocks: The Key to Agentic Context Management
AI Summary
Letta's product thesis in article form. Memory blocks are labeled, character-limited sections of the context window that persist across turns — a direct descendant of MemGPT's core memory, now shipped as an API. The post argues that treating context as structured slots (persona, human, project) rather than a flat string is what separates agents with stable identity from chatbots that reset. This is the piece to read before evaluating any memory platform, because it names the abstraction most others are quietly copying.
