THE PRACTICAL TAKEAWAY

Match the creative to the placement’s actual specification. The same image or card should not be stretched into every format.

The best format makes the offer easier to understand at the moment someone sees it.

A card gives the offer a clear shape.

A compact sponsored card can bring together a brand, an image, a headline, and a short description. Each element needs to earn its space. Use the headline to explain the value, the copy to add one useful detail, and the visual to help someone recognize what is being offered.

An image can make the experience tangible.

Visual formats can help a person imagine a product, a service, or an experience. In October 2026, OpenAI announced a new visual format starting with a select advertiser test during image generation. A format announcement is a reason to investigate access, rather than assume every account can run it.

A collection helps people explore.

A product collection can present more than one item or direction. The creative needs a consistent theme and enough variation to make exploration worthwhile. A list of unrelated products is harder to understand than a selection with a clear purpose.

Inline needs particularly careful copy.

Inline formats use less visual space. The words carry more of the work. Keep the value concrete, the destination relevant, and the sponsorship disclosure clear.

Start with the platform, then design the experience.

Appearance and supported capabilities vary across ChatGPT and conversational ad networks such as Koah and Gravity. Check current requirements, eligibility, and placements before producing the creative. Our format previews show the structure of these experiences; final creative is built to the account’s available specifications.

Design to the actual space.

For a compact card, preserve a useful thumbnail and a readable text column. For an image placement, let the artwork retain its intended proportions. For a carousel, keep tiles consistent and make horizontal browsing clear. Those are design recommendations, not universal platform dimensions.

Our website examples are coded illustrations of format structure. They are not live campaigns, guaranteed inventory, or proof of advertiser access. Before launch, preview the actual creative in the platform, check the destination, and confirm the current account requirements.
