SmartRAG is a modular Python library designed for retrieval-augmented generation (RAG) workflows with large language models. It combines document ingestion, vector indexing, and state-of-the-art LLM APIs to deliver accurate, context-rich responses. Users can import PDFs, text files, or web pages, index them using popular vector stores like FAISS or Chroma, and define custom prompt templates. SmartRAG orchestrates the retrieval, prompt assembly, and LLM inference, returning coherent answers grounded in source documents. By abstracting the complexity of RAG pipelines, it accelerates development of knowledge base Q&A systems, chatbots, and research assistants. Developers can extend connectors, swap LLM providers, and fine-tune retrieval strategies to fit specific knowledge domains.

A2A4J is a lightweight Java framework designed for building autonomous AI agents. It offers abstractions for agents, tools, memories, and planners, supporting asynchronous execution of tasks and seamless integration with OpenAI and other LLM APIs. Its modular design lets you define custom tools and memory stores, orchestrate multi-step workflows, and manage decision loops. With built-in error handling, logging, and extensibility, A2A4J accelerates the development of intelligent Java applications and microservices.

Flat AI is a minimal-dependency Python framework from MindsDB designed to embed AI capabilities into products quickly. It supports chat, document retrieval and QA, text summarization, and more through a consistent interface. Developers can connect to OpenAI, Hugging Face, Anthropic, and other LLMs, as well as popular vector stores, without managing infrastructure. Flat AI handles prompt templating, batching, caching, error handling, multi-tenancy, and monitoring out of the box, enabling scalable, secure deployment of AI features in web apps, analytics tools, and automation workflows.

Backmesh is a thoroughly tested Backend as a Service (BaaS) that offers an LLM API Gatekeeper, allowing your app to securely call LLM APIs. Using JWT authentication, configurable rate limits, and API resource access control, Backmesh ensures that only authorized users have access while preventing API abuse. Additionally, it provides LLM user analytics without extra packages, enabling identification of usage patterns, cost reduction, and improvements in user satisfaction.
