cpp-langchain implements core features from the LangChain ecosystem in C++. Developers can wrap calls to large language models, define prompt templates, assemble chains, and orchestrate agents that call external tools or APIs. It includes memory modules for maintaining conversational state, embeddings support for similarity search, and vector database integrations. The modular design lets you customize each component—LLM clients, prompt strategies, memory backends, and toolkits—to suit specific use cases. By providing a header-only library and CMake support, cpp-langchain simplifies compiling native AI applications across Windows, Linux, and macOS platforms without requiring Python runtimes.

Deep Research AI Agent is an open-source Python framework designed for conducting comprehensive research tasks. It leverages integrated web search, PDF ingestion, and NLP pipelines to discover relevant sources, parse technical documents, and extract structured insights. The agent chains requests through LangChain and OpenAI, enabling context-aware question answering, automated citation formatting, and multi-document summarization. Researchers can adjust search scopes, filter by publication date or domain, and output reports in markdown or JSON. This tool minimizes manual literature review time and ensures consistent, high-quality summaries across diverse research domains.

Knowledge-Discovery-Agents provides a modular set of pre-built and customizable AI agents designed to extract structured insights from PDFs, CSVs, websites, and other sources. It integrates with LangChain to manage tool usage, supports chaining of tasks like web scraping, embedding generation, semantic search, and knowledge graph creation. Users can define agent workflows, incorporate new data loaders, and deploy QA bots or analytics pipelines. With minimal boilerplate code, it accelerates prototyping, data exploration, and automated report generation in research and enterprise contexts.

Meta-Agent-with-More-Agents is an extensible open-source framework that implements a meta agent architecture allowing multiple specialized sub-agents to collaborate on complex tasks. It leverages LangChain for agent orchestration and OpenAI APIs for natural language processing. Developers can define custom agents for tasks like data extraction, sentiment analysis, decision-making, or content generation. The meta agent coordinates task decomposition, dispatches objectives to appropriate agents, gathers their outputs, and iteratively refines results via feedback loops. Its modular design supports parallel processing, logging, and error handling. Ideal for automating multi-step workflows, research pipelines, and dynamic decision support systems, it simplifies building robust distributed AI systems by abstracting inter-agent communication and lifecycle management.

Solana AI Agent Mult via Web3.js. The agent automatically signs transactions using a configured wallet keypair, submits them to a Solana RPC endpoint, and monitors confirmations. Its modular architecture allows easy extension with custom prompt templates, chains, and instruction builders, enabling use cases such as automated NFT minting, token swaps, wallet management bots, and more.

Virtual Scientists V2 serves as a modular AI agent framework tailored for scientific research. It defines multiple virtual scientists—Chemist, Physicist, Biologist, and Data Scientist—each equipped with domain-specific knowledge and tool integrations. These agents utilize LangChain to orchestrate API calls to sources like Semantic Scholar, ArXiv, and web search, enabling automated literature retrieval, contextual analysis, and data extraction. Users script tasks by specifying research objectives; agents autonomously gather papers, summarize methodologies and results, propose experimental protocols, generate hypotheses, and produce structured reports. The framework supports plugins for custom tools and workflows, promoting extensibility. By automating repetitive research tasks, Virtual Scientists V2 accelerates insight generation and reduces manual effort across multidisciplinary projects.

Coffee-Shop-AI-Agents is an open-source framework for building and deploying specialized AI agents that automate key coffee shop functions. Leveraging LangChain and OpenAI models, the project provides modular agents, including a barista agent that handles complex beverage orders, offers customization recommendations, and manages ingredient availability. The cashier agent processes payments, issues digital receipts, and tracks sales metrics. A manager agent generates inventory forecasts, suggests restocking schedules, and analyzes performance data. With customizable prompts and pipeline configurations, developers can quickly adapt the agents to unique shop policies and menu items. The repository includes setup scripts, API integrations, and example workflows to simulate realistic customer interactions and operational analytics in a developer-friendly environment.

ImageAgent is a Python-based AI agent framework that connects to OpenAI’s APIs and vision models to perform text-to-image generation, image editing (inpainting, style transfer), and image analysis (captioning, object detection). It uses LangChain-like agent orchestration to manage multiple steps autonomously, handles prompt parsing, and can be extended with custom tools and pipelines for tailored image workflows.

The RAG-based Intelligent Conversational AI Agent combines a vector store-backed retrieval layer with Google’s Gemini LLM via LangChain to power context-rich, conversational knowledge extraction. Users ingest and index documents—PDFs, web pages, or databases—into a vector database. When a query is posed, the agent retrieves top relevant passages, feeds them into a prompt template, and generates concise, accurate answers. Modular components allow customization of data sources, vector stores, prompt engineering, and LLM backends. This open-source framework simplifies the development of domain-specific Q&A bots, knowledge explorers, and research assistants, delivering scalable, real-time insights from large document collections.

AGNO AI Agents delivers a suite of customizable, pre-built AI agents that handle a variety of tasks: summarizing large documents, scraping and interpreting web content, answering domain-specific queries, reviewing source code, analyzing data sets, and powering chatbots with memory. Its modular design lets you plug in new tools or integrate external APIs. Agents are orchestrated via LangChain pipelines and exposed through REST endpoints. AGNO supports multi-agent workflows, logging, and easy deployment, enabling developers to accelerate AI-driven automation in their apps.
