Stash is an open-source persistent memory infrastructure for AI agents built on PostgreSQL and pgvector. Unlike retrieval-augmented generation, which searches static documents, Stash actively learns from agent experience — consolidating raw observations into facts, relationships, causal links, and higher-order patterns over time. The system exposes 28 MCP tools covering the full cognitive stack: episode storage, fact synthesis, entity graph management, goal tracking, failure pattern recognition, and self-correction when contradictions emerge. It deploys via Docker Compose in three steps and works with any OpenAI-compatible API — Claude, GPT, local models via Ollama. Hierarchical namespaces let agents keep user facts separate from project facts separate from self-knowledge. This fills a real gap in the agent ecosystem. Most agent frameworks treat each session as stateless, which means agents repeat the same mistakes and lose hard-won context. Stash gives agents a persistent cognitive layer that compounds. It surfaced on Hacker News this week to notable developer interest and is worth watching as MCP adoption accelerates.

Text Generation Inference by Hugging Face is a Rust-based LLM serving solution with continuous batching, tensor parallelism, and production-ready performance.
Reviewer scorecard
“The 28 MCP tools are the right abstraction level — my Claude Desktop agents can now actually remember what I've told them across sessions without me writing my own memory layer. The Docker Compose setup is clean and the pgvector backend is production-ready.”
“Tight Hugging Face integration means easy model loading. Rust implementation provides good performance guarantees.”
“The consolidation pipeline sounds elegant in theory but in practice you're letting an LLM synthesize 'causal links' and 'higher-order patterns' from raw observations. That's a recipe for hallucinated beliefs that compound over time. I'd want rigorous testing before trusting this in any production agent.”
“vLLM has won the mindshare battle. TGI is solid but the community and ecosystem around vLLM are larger.”
“Persistent memory is the missing piece between 'AI assistant' and 'AI colleague.' Stash's self-correction and failure pattern recognition are early implementations of what agents will need to become genuinely reliable over long time horizons.”
“Hugging Face's ecosystem play — models, datasets, spaces, inference — creates a compelling end-to-end platform.”
“Finally an agent that remembers my brand guidelines, tone preferences, and past feedback without me repeating myself every session. The namespace hierarchy means I can have separate memories for different clients.”
