OpenAI's Deep Research: Advanced AI for In-Depth Analysis
Launched in February 2025, OpenAI's Deep Research is designed to autonomously conduct multi-step research tasks, emulating the analytical prowess of human experts.

Perplexity AI introduced its Deep Research Tool to democratize access to advanced research capabilities. Leveraging a customized version of the DeepSeek-R1 model, it delivers comprehensive reports in approximately 2 to 4 minutes. Notably, Perplexity offers this service for free, with Pro users paying $20 per month for enhanced features such as unlimited pro searches (300+ per day), access to multiple AI models including GPT-4 and Claude-3, and the ability to upload and analyze unlimited files.
