OpenAI announced a round of product updates to ChatGPT Ads late on Friday, October 16. The new visual formats under test include wider ad cards, larger images on desktop and more prominent, full-width images on mobile, running on advertisers' existing campaigns and creative.

Advertisers with active campaigns now receive weekly performance emails comparing results with the previous week, and can report bugs or suggest improvements from the Ads Manager account menu. A redesigned Conversions page pulls together conversion activity, event trends, optimization status and diagnostic warnings.

The update builds on OpenAI's October 5 announcement of a visual ad format during image generation, and adds new measurement partners. Early partner numbers remain just that: DV Rockerbox measured WeightWatchers' cost per acquisition at 15.3% below its paid-search benchmark, and Triple Whale found 93% of Portland Leather's ChatGPT Ads visitors were new.
