The model has a general understanding of heap exploitation — it can describe what tcache is, explain the concept of a stash...3h ago·8 min read
claw-stack.hashnode.devBuilding a Persistent Memory System for AI AgentsThe canonical advice for giving an AI agent memory is: use a vector database. Store embeddings, do similarity search, retrieve relevant chunks. Good advice for RAG systems. Not necessarily right for an agent that needs to remember what it did last Tu...4h ago·4 min read
