OpenAI Updates ChatGPT Deep Research Viewer

OpenAI is updating ChatGPT’s Deep Research tool with a full-screen viewer that separates reports from chat, adds a left-side table of contents and right-side sources, and supports focusing research on specific websites and connected apps. The update (rolling out to Plus and Pro users today, with Go and free users following shortly) also enables real-time progress tracking, scope edits during generation, and report downloads in Markdown, Word, and PDF.
