LangGraph4j represents AI agent operations—LLM calls, function invocations, data transforms—as nodes in a directed graph, with edges modeling data flow. You create a graph, add nodes for chat, embeddings, external APIs or custom logic, connect them, and execute. The framework manages execution order, handles caching, logs inputs and outputs, and lets you extend with new node types. It supports synchronous and asynchronous processing, making it ideal for chatbots, document QA, and complex reasoning pipelines.

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.

Local LLM with Function Calling allows developers to create AI agents that run entirely on local hardware, eliminating data privacy concerns and cloud dependencies. The framework includes sample code for integrating local LLMs such as LLaMA, GPT4All, or other open-weight models, and demonstrates how to configure function schemas that the model can invoke to perform tasks like fetching data, executing shell commands, or interacting with APIs. Users can extend the design by defining custom function endpoints, customizing prompts, and handling function responses. This lightweight solution simplifies the process of building offline AI assistants, chatbots, and automation tools for a wide range of applications.

Simple-Agent is an open-source AI agent framework written in Python that leverages the OpenAI API to create modular conversational agents. It allows developers to define tool functions that the agent can invoke, maintain context memory across interactions, and customize agent behaviors via skill modules. The framework handles request routing, action planning, and tool execution so you can focus on domain-specific logic. With built-in logging and error handling, Simple-Agent accelerates the development of AI-powered chatbots, automated assistants, and decision-support tools. It offers easy integration with custom APIs and data sources, supports asynchronous tool calls, and provides a simple configuration interface. Use it to prototype AI agents for customer support, data analysis, automation, and more. The modular architecture makes it straightforward to add new capabilities without altering core logic. Backed by community contributions and documentation, Simple-Agent is ideal for both beginners and experienced developers aiming to deploy intelligent agents quickly.

With AI Agents is a code-first framework in TypeScript that helps you define and orchestrate multiple AI Agents, each with distinct roles such as planner, executor, and memory. It provides built-in memory management to persist context, a function-calling subsystem to integrate external APIs, and a CLI interface for interactive sessions. By composing agents in pipelines or hierarchies, you can automate complex tasks—like data analysis pipelines or customer support flows—while ensuring modularity, scalability, and easy customization.

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.

CL4R1T4S empowers developers to build AI agents by offering core abstractions: Agent, Memory, Tools, and Chain. Agents can use LLMs to process input, call external functions, and maintain context across sessions. Memory modules allow storing conversation history or domain knowledge. Tools can wrap API calls, allowing agents to fetch data or perform actions. Chains define sequential steps for complex tasks like document analysis, data extraction, or iterative querying. The framework handles prompt templates, function calling, and error handling transparently. With CL4R1T4S, teams can prototype chatbots, automations, and decision support systems, leveraging Clojure’s functional paradigm and rich ecosystem.

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.

EasyAgent provides a comprehensive framework for constructing autonomous AI agents in Python. It offers pluggable LLM backends such as OpenAI, Azure, and local models, customizable planning and reasoning modules, API tool integration, and persistent memory storage. Developers can define agent behaviors through simple YAML or code-based configurations, leverage built-in function calling for external data access, and orchestrate multiple agents for complex workflows. EasyAgent also includes features like logging, monitoring, error handling, and extension points for tailored implementations. Its modular architecture accelerates prototyping and deployment of specialized agents in domains like customer support, data analysis, automation, and research.

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.
