OpenAI is replacing the manual bid caps in ChatGPT Ads with target-based options, starting Monday, November 9, and the old controls retire on January 1, 2027. The change reaches every advertiser on Max Bid or Max CPC, whether or not they act. Search Engine Land reported the details on Thursday, citing an email OpenAI sent to advertisers.

In that email, OpenAI wrote, “We’re evolving ChatGPT Ads to be more intelligent by default, taking on more of the work of managing campaigns so you can focus on the results that matter to your business.” The practical meaning is less direct control over each auction.

Two new strategies are launching. Target CPA (cost per action) takes the place of Max Bid whenever an advertiser builds a conversion campaign in Ads Manager. The advertiser names an average price per conversion, a purchase or a lead for example, and the system steers bids and delivery toward it.

Target CPC (cost per click) takes over from Max CPC on newly created click campaigns. The difference from a cap matters. A cap limits each individual bid, whereas a target lets the system go higher or lower in any given auction. The stated goal, per OpenAI, is the maximum number of clicks the budget can buy while the average CPC drifts toward the advertiser’s figure.

Existing campaigns keep running as Max Bid or maximum CPC campaigns for now. Advertisers who want a target can change their bidding strategy. After January 1, 2027, existing conversion campaigns still on Max Bid move to Target CPA, and click campaigns still on Max CPC move to Target CPC.

The autobid option, Maximize results, now carries the name intelligent bidding. OpenAI says its system will keep adjusting bids and delivery automatically to get the most results from the budget. The name is new, and the source describes no change in how it works.

Cost targets become available on November 9. OpenAI wrote, “Starting Monday, November 9, you can optionally choose a cost target in Ads Manager when you create a campaign or update an existing one.”

OpenAI recommends advertisers start the transition now. Its checklist has three parts. First, verify that Pixel or Conversions API passes the chosen conversion event into the campaign’s linked data source. Second, watch the Event Quality Score (EQS) warnings and close any signal gaps they flag. Third, set targets from what recent campaigns really cost per conversion or click.

The warning in that guidance deserves attention. OpenAI says that tight targets, or poor conversion signals, can cut ad delivery and strand part of the budget. A cap protects spend by refusing expensive auctions. A target asks the system to hit an average, and if the conversion data feeding it is thin or wrong, the optimization has little to work with.

The announcement contains no performance data. It does not say how Target CPA or Target CPC compares with Max Bid or Max CPC on cost or volume, and the guidance comes from the platform selling the ads. Search Engine Land’s own take is that the update could shift cost, return on investment and results.

For search teams, the useful part is the order of work. Conversion tracking quality now decides how well the bidding performs, so it is the first thing to audit.

Teams running ChatGPT Ads should check their tracking setup before November 9, set targets from recent actual CPA or CPC rather than aspirations, and decide well before January 1 whether each legacy campaign moves on its own terms or on OpenAI’s.
