以物件儲存為基礎的圖資料庫，為代理記憶與上下文而生
圖資料、預寫日誌、值與索引全部存放在 S3 相容儲存中，並採熱/溫/冷分層策略，相較常駐記憶體的圖資料庫大幅降低基礎設施成本。
一次查詢即可同時進行圖遍歷與向量、BM25、重排序搜尋，代理無需再編排四套獨立系統。
所有變更都被記錄，代理可以回溯發生了什麼、何時發生、順序如何，支援可稽核性與長期運行的代理流程。
透過 Bolt 提供 OpenCypher，並搭配 HTTP API 與 SDK，熟悉屬性圖的團隊可快速上手。
在你的 Postgres 上為 AI 代理提供圖、向量與文字檢索
透過一致的介面同時查詢圖、向量、全文與混合檢索，不必把多個系統拼湊在一起。
開源引擎 pgGraph 可跨紀錄沿關係遍歷，不必搬移資料即可實現多跳與最短路徑式檢索。
以嵌入為基礎的語意搜尋結合稀疏、全文比對，兼顧語意與精確詞條的查詢需求。
儀表板遊樂場、用於匯入與設定的 CLI，以及強型別 Python SDK，讓原型驗證到正式上線一氣呵成。
Pinecone is a managed vector database and AI knowledge platform for building retrieval-augmented generation (RAG), semantic search, and agent memory. It stores vector embeddings at scale, makes writes searchable within seconds with no index tuning, and keeps p99 latency steady as data grows. Pinecone powers products for more than 10,000 customers and over a million developers worldwide.

免費 / 開源Honcho is an open-source memory layer for AI agents. It ingests messages, indexes them, and runs background reasoning so agents can recall who a user is, what happened before, and what to do next — across sessions, tools, and machines.
Zilliz is the company behind Milvus, the open-source vector database, and offers Zilliz Cloud — a fully managed vector database service built for large-scale AI retrieval, RAG, and similarity search workloads.
免費 / 開源Qdrant is an open-source vector search engine and database, written in Rust, for high-performance similarity search in AI applications.
免費 / 開源SmythOS is an agentic AI platform with two sides: a visual, drag-and-drop Agent Studio for building AI agents without code, and the open-source SmythOS Runtime Environment (SRE) — an SDK and CLI for running production agents with code. It abstracts LLMs, vector databases, storage and caching behind one unified API so agent logic can be written once and scaled across local, cloud and edge environments.

免費 / 開源EverMemOS (also described as EverOS) by EverMind is a memory operating system for AI agents and applications. It adds persistent, self-evolving memory on top of stateless LLMs: agents store multimodal content, retrieve it through hybrid mRAG, distill repeated patterns into reusable Skills, and keep facts in sync over time.
