# Agent Frameworks — Maximem field notes > Building AI agents with LangChain, LangGraph, CrewAI, LlamaIndex, the OpenAI Agents SDK, Google ADK, Mastra and more, including adding long-term memory to each. Every agent framework ships some notion of memory, and almost none of them keep it past the end of a session. LangGraph checkpoints a thread and the OpenAI Agents SDK hands you a session object; what happens when the same user returns next week is left to you. These articles work through one framework at a time: how its state and memory model behaves, where it stops, and how to add persistent memory without rewriting your agent. The Maximem Synap integration guides here cover LangChain, LangGraph, LlamaIndex, CrewAI, AutoGen, Semantic Kernel, Mastra, the Vercel AI SDK, Google ADK, Pydantic AI, the Claude Agent SDK, the OpenAI Agents SDK, LiveKit and Pipecat. ## All 14 articles - [Maximem Synap's Agent Memory Now Available for Pipecat](https://www.maximem.ai/blog/pipecat-memory-synap-integration) — June 3, 2026: Maximem Synap's persistent agent memory now integrates with Pipecat.
