ChatGPT Ads began rolling out a wider standard ad card that fills more of the desktop conversation

OpenAI told advertisers in its weekly email that a new, wider standard ad card is rolling out, using more of the conversation width on desktop. Existing campaigns and creative carry over, so advertisers need take no action.

The change is cosmetic for setup but gives each ad more screen real estate inside the chat, which is likely to shift click-through rates. Search Engine Roundtable reproduced the announcement from OpenAI's advertiser email and published a screenshot of the wider card.
