According to @OpenAI on Twitter, Deep Research now lets users connect to apps in ChatGPT, perform site-specific searches, track real-time research progress with the ability to interrupt and add follow-ups or new sources, and view fullscreen reports. As reported by OpenAI’s official announcement, these capabilities streamline end-to-end research workflows inside ChatGPT, enabling enterprise teams to validate sources faster, centralize citations, and export report-style outputs for stakeholders. According to OpenAI’s post, the real-time progress tracking and mid-run intervention reduce iteration cycles for tasks like competitive analysis, literature reviews, and due diligence, while app connections and targeted site search improve data coverage and retrieval precision for business research.
