LocalAI

A comprehensive single-package Retrieval-Augmented Generation platform built on Langflow, Docling, and OpenSearch, providing a complete pipeline from document parsing to vector retrieval and generation with multi-model and multi-vector-database support.

Tencent's open-source LLM-powered framework for deep document understanding, semantic retrieval, and context-aware answers using RAG.

Opinionated RAG framework for integrating GenAI into your apps. Works with any LLM, any vectorstore, any files — so you can focus on your product instead of building RAG pipelines.

Run any open-source LLMs such as DeepSeek and Llama as OpenAI-compatible API endpoints in the cloud. Supports fine-tuning, quantization, and distributed inference for production-grade LLM deployment.
