Advanced Agents Cookbooks is a community-driven GitHub project offering a library of AI agent recipes built on LangChain. It covers memory modules for context retention, custom tool integrations for external data and API calls, function-calling patterns for structured responses, chain-of-thought planning for complex decision-making, and multi-step workflow orchestration. Developers can use these ready-made examples to understand best practices, customize behavior, and accelerate the development of intelligent agents that automate tasks such as scheduling, data retrieval, and customer support.

Cyrano is an open-source Python framework and CLI for creating AI agents that orchestrate large language models and external tools through natural language prompts. Users can define custom tools (functions), configure memory and token limits, and handle callbacks. Cyrano handles parsing JSON responses from LLMs and executes specified tools in sequence. It emphasizes simplicity, modularity, and zero external dependencies, enabling developers to prototype chatbots, build automated workflows, and integrate AI capabilities into applications quickly.

gpt-func-calling is a developer toolkit that showcases OpenAI’s function calling feature, allowing chat-based AI to interact with external services. By defining function signatures in JSON, developers guide GPT-3.5/4 to recognize when to call a function, automatically format arguments, and handle the response in a structured manner. This streamlines integration with weather APIs, database queries, or custom business logic, ensuring consistent, reliable outputs without manual parsing.

LLM Functions provides a simple framework to bridge large language model responses with real code execution. You define functions via JSON schemas, register them with the library, and the LLM will return structured function calls when appropriate. The library parses those responses, validates the parameters, and invokes the correct handler. It supports synchronous and asynchronous callbacks, custom error handling, and plugin extensions, making it ideal for applications that require dynamic data lookup, external API calls, or complex business logic within AI-driven conversations.
