enhance_llm provides a modular framework for orchestrating large language model calls in defined sequences, allowing developers to chain prompts, integrate external tools or APIs, manage conversational context, and implement conditional logic. It supports multiple LLM providers, custom prompt templates, asynchronous execution, error handling, and memory management. By abstracting the boilerplate of LLM interaction, enhance_llm streamlines the development of agent-like applications—such as automated assistants, data processing bots, and multi-step reasoning systems—making it easier to build, debug, and extend sophisticated workflows.

LangGraph provides a graph-based abstraction for designing AI agent workflows. Developers define nodes that represent prompts, tools, data sources, or decision logic, then connect these nodes with edges to form a directed graph. At runtime, LangGraph traverses the graph, executing LLM calls, API requests, and custom functions in sequence or in parallel. Built-in support for caching, error handling, logging, and concurrency ensures robust agent behavior. Extensible node and edge templates let users integrate any external service or model, making LangGraph ideal for building chatbots, data pipelines, autonomous workers, and research assistants without complex boilerplate code.
