ChatGPT Ad Formats and Specs: Single Image, Multi-Image, and the Rules

What a ChatGPT Ad Actually Is

ChatGPT ads appear below ChatGPT's response, clearly labeled and visually separate from the answer. OpenAI is unambiguous that ads run on separate systems from the chat model - your ad sits next to the conversation, never inside it.

As of November 2026 there are two formats, both available for standard campaigns with Reach, Clicks, or Conversions objectives:

• Single image - the standard ad unit, available since launch
• Multiple images - an open beta introduced in Ads Manager on October 26, 2026, following the same headline and description requirements

Anatomy of the Ad Unit

Every ChatGPT ad contains the same components:

• Advertiser name - your brand as shown to users
• Favicon - your logo, rendered small; it must be legible at favicon size
• Title - the headline of the ad
• Copy - the description text
• Landing page - the click destination
• Image asset - your creative (or multiple, in the beta format)

Two implications worth internalising. First, this is a compact unit - there is no 30-headline RSA machinery here, so each element carries more weight. Second, every element is also a relevance signal: the delivery system reads your title, copy, and landing page when deciding which conversations you belong in. Specs are not just compliance; they are targeting.

Title Rules: Informative Beats Clever

OpenAI's title guidance, paraphrased from its Help Center:

• Spell out the value clearly - it should be immediately obvious what the product offers or why it is useful
• Keep titles concise - clear, focused language within the recommended character limits
• Prioritise information over slogans - a user mid-conversation is comparing options, not decoding wordplay

The pattern that works: [what it is] + [who it is for] or [what it is] + [the concrete outcome]. "Flat-rate bookkeeping for freelancers" beats "Money, mastered."

Copy Rules: Benefit-Focused or Invisible

OpenAI explicitly states that ads with clear, specific, benefit-focused copy are more likely to be relevant to users. Benefit-focused means explaining practical value - what it does, who it is for, when it helps - rather than a catchy line or generic call to action.

And the structural rule that changes how you build campaigns: build for coverage. A high volume of diverse ads, with multiple title and copy variations per offering, gives the system more conversations where you are relevant. Each variation must be a genuinely different angle - repeating the same message with shuffled words does not count.

Image Guidance

Your image renders alongside the unit below a conversational answer, so it competes with text, not a feed. Practical implications:

• Make the product or outcome recognisable at a glance
• Keep text on the image minimal - your copy field does that job
• The favicon and image are both yours; they should look like the same company
• For the multi-image beta, each image should show something different (use cases, angles, variants), mirroring the distinct-angles rule for text

The Policy Rules That Get Ads Rejected

Creative, image, and landing page must all comply with OpenAI's ads policies. The rejection triggers OpenAI names explicitly: ads that are misleading, inconsistent, or include disallowed content. Inconsistent is the one that catches experienced advertisers - if your title promises one thing and the landing page leads with another, that is a policy problem here, not just a conversion-rate problem.

Frequently Asked Questions

What ad formats does ChatGPT support?

Two as of November 2026: a single-image ad unit and a multi-image format in open beta (added October 26, 2026). Both work with Reach, Clicks, and Conversions objectives and share the same headline and description requirements.

What are the components of a ChatGPT ad?

Advertiser name, favicon (logo), title, copy (description), landing page, and image asset. Ads appear below ChatGPT responses, clearly labeled.

Are there character limits for ChatGPT ads?

OpenAI's guidance says to keep titles concise and within recommended limits; check the current Ads Manager interface for exact limits, as beta-era specs evolve.

Can video ads run on ChatGPT?

OpenAI's documented formats are image-based (single and multi-image). Its creative guidance does not describe a video unit - plan around images and strong copy.

Why was my ChatGPT ad rejected?

OpenAI names three explicit rejection triggers: misleading content, inconsistency (between creative, image, and landing page), and disallowed content under its ads policies. Fix the specific issue and resubmit rather than resubmitting unchanged.
