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.

LangGraph provides a versatile graph-based interface to orchestrate language model operations and data transformations in complex AI workflows. Developers define a graph where each node represents an LLM invocation or data processing step, while edges specify the flow of inputs and outputs. With support for multiple model providers such as OpenAI, Hugging Face, and custom endpoints, LangGraph enables modular pipeline composition and reuse. Features include result caching, parallel and sequential execution, error handling, and built-in graph visualization for debugging. By abstracting LLM operations as graph nodes, LangGraph simplifies maintenance of multi-step reasoning tasks, document analysis, chatbot flows, and other advanced NLP applications, accelerating development and ensuring scalability.
