ChatGPT with Ads: The Model Changes
OpenAI has introduced advertising into ChatGPT. Ads appear in the interface for non-subscriber users. Brands can buy space. The freemium model, until now based on usage limits, now also gets funded by advertisers.
Why Now
ChatGPT's operating costs are enormous. Every response generated consumes significant computational resources. A subscription-only model doesn't cover mass access.
Advertising solves the economic equation. Users who don't pay get monetized through ads. Those who pay for a Plus or Enterprise subscription don't see ads.
How the Format Works
Ads don't interrupt the response. They appear as contextual suggestions, related to the topic of the conversation. If you're talking about travel, you might see a sponsored link to a hotel or a flight aggregator.
OpenAI has stated that conversations aren't sold to advertisers. Data shared with brands is aggregated and anonymous. Ads don't appear in sensitive contexts.
The Comparison with Anthropic
Anthropic's Claude is going in the opposite direction. No advertising. A model based entirely on subscriptions. Two visions of AI's future: one funded by advertisers, one funded by users.
The market's response will determine which model becomes dominant. But the precedent of the last thirty years of the internet suggests the free, ad-supported model always reaches a wider user base.
What This Means for Marketers
Contextual advertising in a conversational context is different from display advertising. The user isn't browsing. They're looking for an answer. The ad appears at the exact moment intent is formed.
Google built an empire on this principle with search. ChatGPT adds a layer: the answer is generated, not selected. The ad slots into a context that's already qualified.
For advertisers, it's a channel worth watching. The formats are still experimental. But the logic is the same as advertising on Google Search: be present where demand is formed.
