OpenAI has announced an expansion of advertising within ChatGPT through a new format called Sponsored Agents. Under this scheme, brands would be able to fund the presence or promotion of dedicated conversational agents tied to their products or services, integrated directly into the chat experience. The move builds on earlier, more discreet advertising tests the company had begun rolling out, such as sponsored links or recommendations, before moving toward this agent-based approach.
The shift is notable given OpenAI's earlier reluctance toward advertising. Sam Altman had previously voiced concerns about how ad-driven models could undermine user trust in the product. Financial pressure tied to infrastructure costs and the broader push toward profitability appears to be driving the company to diversify revenue beyond ChatGPT Plus and Pro subscriptions and API access.
The introduction of sponsored agents raises both practical and ethical questions. It remains to be seen how OpenAI will clearly distinguish responses generated by advertiser-funded agents from the model's neutral recommendations, a transparency concern already raised around other AI assistants experimenting with ad formats, including Perplexity and some Google tools. The line between sponsored content and impartial answers is likely to draw scrutiny from both users and regulators.
More broadly, the announcement reflects a wider trend in the conversational AI industry: after a growth phase built on subscriptions, several players are now looking to replicate traditional web advertising models, with the risk of reproducing some of their familiar pitfalls around commercial bias and information quality.
