Graphify + MemMachine: 79× Token Reduction, Zero Vector Database

I help maintain MemMachine — an open-source long-term memory layer for AI agents. It’s a real codebase: 442 source files, 171 docs, a graph database, a SQL store, an MCP server, a REST API, a Python SDK, and integrations with eight different agent frameworks. When a new contributor asks “where does episodic memory actually get written?”, grep, the tool of choice for many AI coding assistants, doesn’t cut it. The answer threads through five files in three folders, plus a docker-compose service definition and a Helm chart. Each question you ask, it has to search all of these files, using the LLM to semantically understand the question and the files, then piece together an answer. This can take a lot of tokens and consume much of the context window.

How I Created a Custom ChatGPT Trained on the CXL Specification Documents

If you’re working with Compute Express Link (CXL) and wish you had an AI assistant trained on all the different versions of the specification—1.0, 1.1, 2.0, 3.0, 3.1… you’re in luck.

Whether you’re a CXL device vendor, a firmware engineer, a Linux Kernel developer, a memory subsystem architect, a hardware validation engineer, or even an application developer working on CXL tools and utilities, chances are you’ve had to reference the CXL spec at some point. And if you have, you already know: these documents are dense, extremely technical, and constantly evolving.
