OpenAI hails 1 million Codex downloads, but warns limits may be coming - but ChatGPT Deep Research users get a whole load of upgrades to boost their work (www.techradar.com)

OpenAI has celebrated over one million downloads of its Codex Mac app just a week after its launch, a surge driven by a 60% increase in users following the release of GPT-5.3-Codex. The app will remain available for free to users on Free and Go plans, though these tiers may face limitations in usage compared to higher-paying subscribers. OpenAI CEO Sam Altman confirmed that while Codex will stay free, limitations are likely to ensure sustainable access for all. In addition to the successful launch, OpenAI has rolled out significant upgrades for users of the Deep Research feature within ChatGPT. New enhancements include a full-screen report viewer for better navigation and usability, downloadable reports in PDF or Word formats, and improved functionality that allows users to focus on specific websites throughout their research projects. These upgrades are aimed at enhancing user experience and productivity, particularly for Plus and Pro users, with Free and Go users set to receive similar updates soon. Moreover, a minor update to the GPT-5.2 model aims to refine the tone of responses, contributing to a more grounded user interaction.
