ChatGPT Ads: New Formats and Measurement Partners Explained

OpenAI updated ChatGPT Ads late on Friday, October 16, 2026. It is testing larger visual formats, redesigned the Conversions page in Ads Manager, added weekly performance emails and named more measurement partners. A separate October 5 announcement added an image-led ad format that starts testing in the US later this month.

For small sellers, this is mostly a signal about where paid advertising is heading. Below are the confirmed facts, the cost math that matters and what to do now.

What changed in ChatGPT Ads?

According to Search Engine Roundtable, there are four changes in Ads Manager, the dashboard where advertisers build and track campaigns:

• Visual formats in testing: wider cards, larger images on desktop and full-width images on mobile. A multi-image format is coming soon. OpenAI says the tests use existing campaigns and creative, with no action required from advertisers.
• A new Conversions page: the overview stays visible on every Conversions tab and shows event volume and trends, the share of active campaigns optimizing for conversions, and warnings that link to the Diagnostics tab.
• Weekly emails: advertisers with active campaigns get an account summary with week-over-week changes.
• Bug reports and feedback: the account menu now offers “Bug report” and “Product feedback”.

Is there a new ad format tied to image generation?

Yes, as a test. Relevant Audience, describing the October 5, 2026 announcement, reports that image-led ads will appear during ChatGPT image generation, clearly labeled and kept separate from the image the user creates. Testing starts later in October in the US with an initial group of advertisers. OpenAI has not published pricing, creative specs or whether Ads Manager will support the format.

Who are the new measurement partners?

Measurement is how you find out whether an ad produced a sale. Search Engine Roundtable lists Northbeam, DV Rockerbox and INCRMNTAL as new measurement partners, plus Kochava, Tenjin and Airbridge for mobile apps. Relevant Audience counts 20 named partners in total, including AppsFlyer, Triple Whale, Adjust, Branch and Singular. The two outlets count differently, so check OpenAI’s own setup guides before you commit to a tool.

OpenAI is also developing brand suitability pilots with DoubleVerify and Integral Ad Science, without access to private conversations, per Relevant Audience. No start dates or sizes were published.

How much does it cost, and who can buy?

TechWyse reports that in May 2026 OpenAI opened a beta self-serve Ads Manager to US businesses, adding cost-per-click (CPC) bidding next to cost per thousand impressions (CPM). OpenAI suggested a starting maximum bid of $3 to $5 per click. The pilot launched with minimum spend as high as $250,000, which fell to $50,000 in April. The article does not confirm whether the minimum has been removed.

Ads show to Free and $8-per-month Go users. Plus, Pro, Business, Enterprise and Education subscribers do not see them. Pilot categories include household and consumer goods, local services, travel and entertainment, and digital products and education.

Can you trust the published results?

Treat them carefully. Relevant Audience cites partner-reported figures, such as a cost per acquisition 15.3% below paid search for one wellness brand and 93% new visitors for a leather goods store. The same source notes that no spend, sample sizes or methods were published. In our view these are marketing showcases, not a result a small seller should plan around.

What is still unknown?

• Pricing and creative specs for the image format.
• Whether the minimum spend is gone for everyone.
• Which partner integrations are live and under what terms.

What should you do now?

If your budget is small, nothing here forces a move. Keep measuring the basics: what you pay to win one sale. A quick example: a $100 product that leaves $30 in margin after costs and fees, advertised at a ROAS of 2 (return on ad spend, so $200 in sales for every $100 spent), earns $60 in gross margin on $100 of ad spend. You lose $40. To break even, ROAS needs to be at least 3.3. The full method is in What Is ROAS?.

If you already run Google campaigns, read Google Ads Channel Prioritization and Budget Caps Explained to see where your spend actually goes. And keep your product feed clean, as in How to List Products on Google for Free With Merchant Center, because a tidy catalog helps on any platform that comes next.

As of October 2026, this reflects what the three sources published. Everything here is in testing and can change, so watch OpenAI’s official advertiser pages.
