ID-based RAG FastAPI: Integration with Langchain and PostgreSQL/pgvector

⚡️next-generation personal AI assistant powered by LLM, RAG and agent loops, supporting computer-use, browser-use and coding agent, demo: https://demo.openagentai.org

Type-safe tools, on-device inference, multi-agent workflows, memory, and guardrails, in one Swift-native runtime

Unified LangChain documentation.

The ultimate LLM/AI application development framework in Go.

Task-scoped authorization for AI agents. Cryptographic warrants constrain tools and arguments, prevent privilege escalation at every delegation hop, and produce signed evidence of what was allowed or denied.

Knowhere extracts, parses, and outputs structured chunks ready for AI Agents and RAG.

Claude Code for Financial Market

A lean, self-hosted AI agent that everyone can use. Each person gets an assistant with its own private computer, their files, skills, app connections and scheduled jobs.

Row-Bot - Personal AI Sovereignty. A local-first AI assistant with integrated tools, a personal knowledge graph, voice, vision, shell, browser automation, scheduled tasks, health tracking, and messaging channels. Run locally via Ollama or add opt-in cloud models. Your data stays on your machine.

OpenTelemetry Instrumentation for AI Observability

This repository will have different projects using AutoGen and Tutorials

AI-powered StartUp Accelerator Engine built with Next.js, LangChain, PostgreSQL + pgvector. Upload, organize, and chat with documents. Includes predictive missing-document detection, role-based workflows, and page-level insight extraction.

What if OpenAI Deep Research and Dify were one platform? OpenAgent — harness architecture for rapidly building vertical AI agents, with deep reasoning loops, visual workflows, RAG, and A2A delegation.

One person, a team of agents. Multi-session CLI that collaborates across terminals; /goal keeps long tasks running; WeChat/WeCom/Feishu gateway lets you call them back when you walk away. Async Python SDK, persistent memory, self-evolving skills.

Build LangChain Applications on AWS

C# implementation of LangChain. We try to be as close to the original as possible in terms of abstractions, but are open to new entities.
