Deep Research AI Agent is an open-source Python framework designed for conducting comprehensive research tasks. It leverages integrated web search, PDF ingestion, and NLP pipelines to discover relevant sources, parse technical documents, and extract structured insights. The agent chains requests through LangChain and OpenAI, enabling context-aware question answering, automated citation formatting, and multi-document summarization. Researchers can adjust search scopes, filter by publication date or domain, and output reports in markdown or JSON. This tool minimizes manual literature review time and ensures consistent, high-quality summaries across diverse research domains.

LLMs provides a unified abstraction over various open-source and hosted language models, allowing developers to load and run models through a single interface. It supports model discovery, prompt and pipeline management, batch processing, and fine-grained control over tokens, temperature, and streaming. Users can easily switch between CPU and GPU backends, integrate with local or remote model hosts, and cache responses for performance. The framework includes utilities for prompt templates, response parsing, and benchmarking model performance. By decoupling application logic from model-specific implementations, LLMs accelerates the development of NLP-powered applications such as chatbots, text generation, summarization, translation, and more, without vendor lock-in or proprietary APIs.
