AI isn’t slowing down, and neither are the changes affecting marketers. June brought several notable updates that could influence how brands get discovered, advertise, and even engage customers at the point of sale. Here’s your June AI in Marketing Rundown.
Google Implemented Open Knowledge Format (OKF)
On June 12th 2026, Google Cloud introduced the Open Knowledge Format (OKF). In short, it’s a new open standard designed to make organizational knowledge easier for AI systems to understand and share.
Rather than locking information into proprietary tools or custom integrations, OKF packages documentation, metadata and business context into simple Markdown files with standardized YAML metadata. In practice, this creates a vendor-neutral format that both humans and AI agents can read more easily, and is intended to improve AI system accuracy through more consistent, structured context.
The prevalence of AI-powered search, assistants and especially autonomous agents is on the rise. An organization’s ability to structure and share their knowledge with these agentic systems may increasingly impact how much value they can expect to extract from these tools.
While OKF seems to be primarily targeting engineering and data teams today, its message of standardized, machine-readable knowledge applies to marketing teams, too, especially those that plan to leverage AI agents as they become more accessible and reliable.

OpenAI Doubles Down on ChatGPT Ads at Cannes Lions
OpenAI made its inaugural appearance at the Cannes Lions advertising festival this month. At the event, a few OpenAI executives pulled a handful of reporters aside to talk shop about ads in ChatGPT.
To get to the heart of their message: A standout quote from CRO Denise Dresser made clear that OpenAI is “…clearly in the advertising business now.”
Earlier this year, OpenAI made its self-serve ChatGPT Ads Manager available to everyone in beta. And this recent Cannes Lions appearance solidifies their plans to continue development and become a real player in the paid ads space.
The messaging the OpenAI cohort shared centered around how ChatGPT is not ‘just another ad platform,’ but a new kind of commercial channel where recommendations and sponsored content are designed to be useful and conversational rather than disruptive.
While it’s still in beta, OpenAI’s doubling down on ads and relatively recent Ads Manager beta release mark a solid and still-early opportunity for marketers to get in on ChatGPT paid media.
Amazon Gets In On Agentic Ads
Amazon unveiled some new tech on Prime Day this year: Alexa+ Agentic Ads.
This new feature introduces a novel function that lets customers discover a product, ask questions, compare options and complete a purchase through a natural conversation with Alexa. The interesting bit here is that all of that takes place directly within the ad itself, i.e., Alexa+ lives within the ad to help users buy without having to navigate away from what initially piqued their interest. It’s a play to simplify the path to purchase.
Typically, most AI or intelligent ad experiences are but a stepping stone on a customer’s path to the point of sale, which largely still happens on a vendor’s website. This is beginning to change, though, and this new feature from Amazon is a big step toward more streamlined purchasing pathways. Alexa+ Agentic Ads essentially gets rid of most of the stepping stones, because the AI agent itself becomes the point of sale.
It’s unclear when this feature will roll out more widely, but right now, select Amazon partners are already testing it out.
Claude Fable 5’s Rollercoaster Launch
Anthropic had an eventful month with the release of Claude Fable 5, its most capable public AI model to date. Originally launched on June 9, the model promised major advances in coding, reasoning and long-running agentic tasks. Just three days later, however, Anthropic suspended access after a U.S. government export-control directive raised national security concerns surrounding its underlying capabilities.
The suspension sparked widespread discussion across the AI industry, particularly among developers who had already begun integrating the model into their workflows. By the end of the month, Anthropic announced that Fable 5 would begin returning through a phased rollout following discussions with U.S. regulators.
As far as product launches (or should I say re-launches) go, this has been a strange one.
Final Thoughts
While none of these announcements spur a dramatic change in strategy, they’re worth watching. AI agents are becoming more accessible, and the quality of information they run on will directly impact how well they perform. If you’re keen on exploring AI agents, Google’s OKF might be of interest.
On the paid media side, ChatGPT advertising is only gaining momentum. Chances are that most, or at least a segment of, your audience is searching on ChatGPT — especially if you’re in the B2B business — and a conversational ad there could be the ticket to your next sale.
