- The Codex has been downloaded more than a million times and users have increased by 60% in one week
- It will remain free for all users, but Free/Go plans may have limits
- Deep Research gets a new viewer and better controls
It’s barely been over a week since OpenAI launched its dedicated Codex Mac app and it has already garnered over a million downloads.
Overall, Codex users also grew 60% in one week after the release of GPT-5.3-Codex, and OpenAI CEO Sam Altman is so pleased with the initial uptake that Free and Go users will continue to get free access to Codex after its launch promotion.
“We will keep Codex available for Free/Go users after this promotion,” Altman confirmed in an X post.
Codex will remain free, Deep Research is renewed
As anticipated, Free and Go subscribers will likely face stricter limits than higher-paying subscribers. “We may have to lower the limits, but we want everyone to be able to try Codex and start building,” Altman added.
Furthermore, OpenAI also shared a new video showing Deep Research’s makeover on YouTube.
Visually, Deep Research now includes a full-screen report viewer so users can open reports in separate windows from the chat interface. Like a well-formatted official report, it includes a table of contents in the left panel for easier navigation, with hyperlinks and anchor tags, and a list of sources in the right panel for better verification and fact-checking.
Users can also download their report as a PDF or Word document for offline viewing and editing.
In terms of functionality, OpenAI has also made it possible to direct ChatGPT to focus on specific websites and connected applications for each deep research project. And on-the-fly edits let you change the scope of your research, add sources, and refine details during progress, rather than having to wait for it to finish.
The changes have been made available to Plus and Pro users with immediate effect; Go and Free users also expect the changes soon.
The changes were also detailed in the ChatGPT release notes, confirming the changes on February 10. A smaller update to the existing GPT-5.2 model was also announced, making responses “more measured and grounded in tone.”
“We updated GPT-5.2 (the snapshot model) in ChatGPT today. It’s not a huge change, but we hope you find it a little better,” Altman added in a separate X post.
