ChatGPT Ads sets November target-bidding transition and January retirement

What changed

OpenAI's help page sets two transition stages. From 9 November 2026, Ads Manager offers Target CPA for new conversion campaigns and Target CPC for new click campaigns. Existing Max Bid and Max CPC controls retire on 1 January 2027. The page calls the automated alternative Intelligent bidding, formerly Maximize Results (Autobid).

The API timetable differs. From 18 November, integrations are advised to use dedicated target fields. Legacy fields remain supported through December, but creating a campaign or changing an ad group's bid type with them selects target bidding and interprets the value as an average-cost goal. Those fields are deprecated from 1 January.

This changes the meaning of a number in a campaign configuration. A target describes an average outcome the system aims for; it does not cap each result or guarantee the achieved average. Choosing a conversion target also does not, by itself, change the billing event to conversions.

For an agency integration, the practical risk is leaving a control labelled as a maximum after its underlying field has acquired target semantics. A client could reasonably interpret that label as a limit. Review the API mapping, interface label and explanation together, then test the supported transition in the intended campaign type. Keep a record of the previous strategy so a performance change can be investigated against the configuration change.

A useful internal handover would identify the campaign owner, the integration owner and the date each route changes. It should also state whether reporting is comparing like-for-like conversion events. These are implementation checks, not a forecast of better performance or a recommendation to raise a particular advertiser's target.

Barry Schwartz reported the change on 5 November. OpenAI's current documentation supports the timetable, but its exact revision date is unverified. The report date should not be mistaken for the date on which the help page first changed. Check the controls available in the account before scheduling a migration.
