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.

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。
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.
Store and query vector embeddings with automatic indexing that requires no manual tuning or algorithm selection.
Writes are acknowledged in under 100ms and become searchable within seconds, while all data is searched in parallel so speed holds at scale.
Connect agents to Pinecone through plugins for Claude Code, Cursor, Copilot, Codex, Gemini CLI, MCP, or a direct REST API with one key.
Serve compiled, governed enterprise knowledge to agents through a single query, cutting token usage and latency versus multi-step RAG loops.

專項更強專為持久化 AI 代理脈絡而設計的向量圖形記憶體 API,提供比 Pinecone 更高階的代理記憶體功能。
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.

專項更強Lightning-fast open-source search engine optimized for keyword and text retrieval, but less tailored for dense vector embeddings.

為大規模企業級應用打造的全託管 Milvus 向量資料庫,提供比 Pinecone 更深入的 SQL 支援。
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.
