OpenAI ChatGPT Deep Research is an AI-powered research agent that autonomously completes complex multi-step research tasks by analyzing text, images, and PDFs across the web, generating detailed reports in minutes.

The tool supports web content, user-uploaded files (TXT, PDF, Word), social media data, tabular data, and multimodal combinations (text + images).

It extracts text/images from PDFs, integrates content with web data, creates structured reports, and maintains contextual understanding, though it occasionally encounters formatting issues with complex PDFs.

Industries such as financial analysis, scientific research, policy assessment, consumer product comparisons, and engineering feasibility studies benefit the most.

ChatGPT Deep Research uses the o3 model optimized for multi-source synthesis while DeepSeek R1 is known for its math/logical reasoning capabilities.

Its unique features include extended reasoning sessions, source verification with audit trails, cross-modal analysis capabilities, and financial-grade report structuring.

Future updates include embedded data visualizations, professional database integrations, collaborative editing features, and enhanced rumor detection algorithms.

It is available to ChatGPT Pro users (100 queries/month), Plus/Teams (limited beta, 20 queries/month), and Enterprise customers with custom plans.

It has 89.7% factual accuracy on financial reports, a 26.6% score on the Human Final Exam benchmark, and a 73% satisfaction rate among early adopters.

Current limitations include no real-time data updates, limited non-English support (25 languages), a maximum 50MB file upload size, and no API access until 2026.
