基于对象存储的图数据库,为智能体记忆与上下文而生
图数据、预写日志、值与索引全部存放在 S3 兼容存储中,并采用热/温/冷分层策略,相比常驻内存的图数据库大幅降低基础设施成本。
一次查询即可同时进行图遍历与向量、BM25、重排序搜索,智能体无需再编排四套独立系统。
所有变更都被记录,智能体可以回溯发生了什么、何时发生、顺序如何,从而支持可审计性与长期运行的智能体流程。
通过 Bolt 提供 OpenCypher,并配有 HTTP API 与 SDK,熟悉属性图的团队可以快速上手。
为 AI 代理在你的 Postgres 上提供图、向量与文本检索
通过一个一致的接口同时查询图、向量、全文与混合检索,无需把多个系统拼在一起。
开源引擎 pgGraph 可跨记录沿关系遍历,无需搬迁数据即可实现多跳与最短路径式检索。
基于嵌入的语义搜索与稀疏、全文匹配相结合,兼顾语义与精确词条的查询需求。
仪表盘演练场、用于导入与配置的 CLI,以及强类型 Python SDK,让原型验证到正式上线一气呵成。
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.

免费 / 开源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.

免费 / 开源Qdrant is an open-source vector search engine and database, written in Rust, for high-performance similarity search in AI applications.
免费 / 开源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.

免费 / 开源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.
