OpenAI Adds New Image Formats to ChatGPT Ads Manager

OpenAI added new image formats, a conversions overview, and weekly performance emails to ChatGPT Ads Manager. Search Engine Roundtable reported the update on October 19. OpenAI made the announcement late on Friday, October 16.

The new formats being tested include wider cards, larger images on desktop, and full-width images on mobile. A multi-image format is coming soon as well. OpenAI said the tests "use existing campaigns and creative, with no action required from advertisers."

That means advertisers don't need to build new creative or change any settings; existing campaigns automatically adapt to the new formats. The approach appears aimed at expanding the visual footprint of ads while keeping extra work off advertisers' plates.

The Conversions tab in Ads Manager was also redesigned. Event volume and trends, the share of active campaigns optimizing for conversions, and warnings linked to the Diagnostics tab are now visible at a glance. The overview stays in view as advertisers move between tabs.

Advertisers running active campaigns now receive a weekly performance summary by email. It includes week-over-week changes along with a link to the full results page in Ads Manager, making it easier to catch major shifts without logging in every day.

New measurement partners were added as well. Northbeam, DV Rockerbox, and INCRMNTAL joined as standard measurement partners, while Kochava, Tenjin, and Airbridge were added for mobile measurement. That gives advertisers more options for connecting their own analytics tools directly.

Previously, reconciling ChatGPT ad performance with other analytics tools often meant moving data manually. The expanded measurement-partner list opens up more room to automate that process.

This update doesn't disclose performance numbers on its own, but it shows how quickly ChatGPT Ads is building out its feature set. As more measurement tools and alerts get added, advertisers have more dashboards to keep track of as well.

ChatGPT Ads has expanded rapidly this year, adding features like Sponsored Agents and measurement tools along the way. This announcement continues that pattern, suggesting OpenAI is working to build a fuller advertising stack in a short span of time.

In Korea

Anyone running or evaluating ChatGPT Ads should check the new conversions overview and weekly emails first, to confirm campaign optimization settings are configured correctly.
