OpenAI Ads update: audiences, conversion matching, carousel & more

OpenAI shipped several Advertiser API updates in quick succession. Here's the read — not a feature dump, but sorted by what actually helps advertisers in practice.

Custom audiences: much more flexible

You can now add, remove or replace members without recreating an audience. Different identifier types may be mixed in the same request, lists under 25,000 matched users work for exclusions, audiences beyond five million members are possible, size ranges are more granular — and the Google Advertising ID (GAID) is now a supported identifier.

In Chatvertise you manage audiences right in the platform — create, fill from a file, merge and exclude — without a detour through the Ads Manager. That add/remove/replace model and the size ranges are already represented on our side.

Better conversion matching

The pixel and Conversions API now accept more fields: hashed phone, first and last name, region and postal code among them; the Conversions API additionally takes list fields and the Android GAID. More clean matching signals usually mean more accurate attribution — and a better basis for optimization.

Carousel reporting at the product level

When a product-feed campaign serves in the multi-product carousel unit, reporting now surfaces carousel card impressions and clicks, plus product-level fields. One thing to keep in mind when reading the numbers: carousel card impressions are not billable and should be read separately from billable ad impressions.

Budget pacing for total budgets

Campaigns with total budgets now spread spend more evenly across the flight instead of burning the budget early. Day-to-day spend still varies with available delivery opportunities — pacing smooths, it doesn't guarantee a fixed daily amount.

Coming soon: optimizing for view-through conversions

OpenAI is introducing a new campaign type that optimizes toward conversions from both clicks and views; billing is impression-based while delivery works toward your conversion goal. More details will follow with the broader rollout — we're watching it.

And the AI plugin inside ChatGPT?

The 'ChatGPT Ads Manager' plugin lets you create and adjust campaigns in plain language right inside ChatGPT, previewing changes for confirmation before applying them. Handy for quick one-off actions. For ongoing management across multiple accounts, dependable dashboards, the structure overview, bulk actions, team access and Shopify import, a dedicated interface like Chatvertise stays the calmer choice — the two complement each other more than they compete.

We keep Chatvertise current with the Advertiser API. Connect your key and try the new capabilities in an interface built to keep the overview.
