This YouTube video demonstrates how to use an open-source alternative to OpenAI's Deep Research, a tool that performs in-depth research using AI. The open-source version, significantly cheaper than the $200/month OpenAI subscription, requires an OpenAI API key and the free Fir Crawl API. The video walks through the setup process (using Docker) and compares the results of both versions on sample research queries, showing similar outputs despite the open-source version's command-line interface.
