OpenAI has expanded its commercial and legal footprint in Brazil. The company is rolling out an advertising pilot for ChatGPT users on free and basic paid tiers, including the ‘Go’ subscription. To support this expansion, OpenAI has updated its privacy policy to allow for ad personalization using contextual signals, such as chat context and ad interactions. The company maintains that ads will be “clearly labeled as sponsored content,” will not influence model outputs, and that advertisers will not have direct access to user conversations.

Parallel to these commercial developments, author Fernando Morais has filed a lawsuit against OpenAI in São Paulo alleging copyright infringement. The legal action claims the unauthorized use of his books to train ChatGPT, characterizing the practice as “parasitic training.” Morais’s legal team argues that the AI can reproduce “detailed structures, arguments, and specific historical descriptions” from protected works, including ‘Chatô: o Rei do Brasil’, ‘Corações Sujos’, and ‘Olga’, thereby undermining the publishing market and authors' livelihoods.

The lawsuit seeks an injunction to suspend the use of his content, a daily fine for non-compliance, and compensation for material and moral damages. While the initial claim is estimated at R$ 100,000, lawyers noted this figure may be revised following a formal expert assessment. The case contributes to a global debate regarding the boundaries of “fair use” and the legality of using internet-available content to train generative AI systems.
