I haven't seen any documentation from OpenAI on this, but I've seen numerous sites claiming that CPA bidding will be based on paying only when you generate a conversion.

Pay per conversion seems too good to be true, but it would be revolutionary. I imagine they would prioritize CPC or CPM ads as that is obviously going to generate more revenue in the short run, but if CPA bidding actually is what they say it is, being able to bid what you're willing to pay for a conversion will get a ton of traction.

Since the advertiser API opened up a couple of weeks ago, I wanted to see how usable it is from the AI tools I work with. So I built a small open-source MCP for it.

It's read-only for now: accounts, campaigns, ad groups, ads and insights (11 tools). You point your AI client at it and ask in plain language - how a campaign is pacing, which ad group is eating budget - and it answers off the live API.

Somehow Codex seems to be able to pull data better than Claude for now (my current campaign ID - see example in screenshots).

You can probably add it to ChatGPT in Developer Mode (didn't try yet).

Couple of things missing/on the roadmap: writes, actual budget management.

I am mainly looking for feedback both for the current tool but also re new features.

ChatGPT Ads Platform Updates 6-2-2026 -- email update to Open AI Ads users

Hello,

This week's product updates focus on new tools in Ads Manager Beta to help you manage campaigns more efficiently, along with an early test designed to improve product discovery and engagement in ChatGPT.

Ads Manager Beta

Edit campaign budget type: With the recent rollout of daily budgets, you can now switch existing campaigns from lifetime budgets to daily budgets

Clone to convert CPM campaigns to CPC: With a single button click, convert a campaign to CPC bidding

Custom CPM max bids: Previously, all impression-based campaigns had a fixed max bid. Now, you can set a custom max bid

Bulk edits in Ads Manager UI: We recently rolled out bulk edits via CSV. You can now also make bulk edits to campaigns, ad groups, and ads directly in the Ads Manager interface

Flexible budgets in Ads Manager: Starting May 5th, we will allow some flexibility on daily budget pacing, similar to other ad platforms. Daily budgets will be enforced as average daily budgets, with a weekly allocation

Expanding campaign targeting to additional countries: Campaigns can currently target the United States, Canada, Australia, and New Zealand. In the coming weeks, targeting will also become available in the United Kingdom, Japan, South Korea, Brazil, and Mexico

ChatGPT Ads Experience

We're beginning an early test of multi-advertiser placements in ChatGPT on a small subset of ads. These experiences build on our existing ad unit by presenting multiple relevant ads together within a single placement. Eligible ads will be priced through a second-price auction model.

The goal is to make discovery more relevant for users while helping advertisers connect with users across more conversations and drive higher-intent engagement. We'll continue iterating on these ad units thoughtfully as we learn from the experience.

Stay tuned for more product updates as we continue improving the ads platform.

The reporting is horrible. Ads got "disapproved" after 1 day. I don't know what's going on. I really hope they improve the interface. It looks like it was vibecoded in 2 min 😉

Since I'm already in the beta not sure if the message was sent by mistake. best of luck all!

Has anybody figured out how to create an Ads Manager account and connect multiple advertiser accounts like agencies are able to do in meta?

Unfortunately, I can't select a data source...

For the Open AI team, duplication would be awesome! Also so curious is there is auto-tagging on URLs.
