vicinity

Lightweight Nearest Neighbors with Flexible Backends

adaptive-classifier

A flexible, adaptive classification system for dynamic text classification

turbovec

A vector index built on TurboQuant, written in Rust with Python bindings

zvec

A lightweight, lightning-fast, in-process vector database

sqlite-vss

widemem-ai

Local-first memory layer for LLM apps and agents. Runs offline on Ollama, sentence-transformers and FAISS; OpenAI and Anthropic optional. Importance scoring, contradiction resolution, confidence-aware retrieval.

adalflow

AdalFlow: The library to build & auto-optimize LLM applications.

edgeproc-core

Decides which partition a vector belongs in when a vector index is split across tenants, users, or time windows: three routing strategies plus result merge-back, one runtime dependency (pydantic), no index of its own. 243 tests, 98% coverage.

edge-proc

For Python apps that ship data to devices: each one checks it's genuine, downloads only changes, and searches offline.

agronaut

An open-source AI agronomy agent that runs locally on your own machine or server, reaches you on Telegram and WhatsApp, and computes aquaponics system designs from a deterministic, source-cited engineering core instead of guessing them.

memvid-sdk

Memory layer for AI Agents. Replace complex RAG pipelines with a serverless, single-file memory layer. Give your agents instant retrieval and long-term memory.

openframe-adapters
