AI Agents is a comprehensive Python framework designed to streamline the development of intelligent software agents. It offers plug-and-play toolkits for integrating external services such as web search, file I/O, and custom APIs. With built-in memory modules, agents maintain context across interactions, enabling advanced multi-step reasoning and persistent conversations. The framework supports multiple LLM providers, including OpenAI and open-source models, allowing developers to switch or combine models easily. Users define tasks, assign tools and memory policies, and the core engine orchestrates prompt construction, tool invocation, and response parsing for seamless agent operation.

LangChain AI Scientist V2 leverages large language models and LangChain’s agent framework to assist researchers at every stage of the scientific process. It ingests academic papers for literature reviews, generates novel hypotheses, outlines experimental protocols, drafts lab reports, and produces code for data analysis. Users interact via CLI or notebook, customizing tasks through prompt templates and configuration settings. By orchestrating multi-step reasoning chains, it accelerates discovery, reduces manual workload, and ensures reproducible research outputs.
