Two of the most closely watched AI developers just moved on their biggest liabilities. Anthropic confirmed a $1.5 billion settlement to resolve claims that it trained its large language models on books without permission. OpenAI introduced new safety standards for teenage users of ChatGPT, including parental controls and an automatic router that shifts sensitive conversations to reasoning models. Together these steps show foundation model builders retooling around intellectual property and user safety as core product and business constraints.
Anthropic’s deal, which requires approval from U.S. District Judge William Alsup in San Francisco, would cover a class action led by authors Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson. Plaintiffs’ lawyers called it “the largest publicly reported copyright recovery in history.” The suit targeted the San Francisco company behind the Claude chatbot and accused it of holding digital copies of more than seven million pirated books in a central library to train its models. The company said it will destroy copies of the books at issue and emphasized its commitment to developing safe AI systems that help people and organizations extend their capabilities, advance scientific discovery, and solve complex problems. The settlement contains no acknowledgment of wrongdoing and a trial had been scheduled for December if no deal had been reached.
The stakes were enormous. If tried, damages could have reached up to $150,000 per pirated work, implying a theoretical exposure of hundreds of billions of dollars. The reported payout structure would broadly allocate about $3,000 for around 500,000 eligible books. Judge Alsup previously found that using books to train AI was “exceedingly transformative,” yet also concluded that Anthropic should stand trial for its use of pirated material. The case has been described as the first to address what constitutes fair use of existing content to train large language models, and several other AI copyright cases are moving through U.S. courts. Anthropic, backed by Google and Amazon, opted to settle while facing that legal backdrop.
For developers and operators, the operational lessons are stark. Training data provenance is not a theoretical worry. Even without an admission of wrongdoing, the cost of clearing legacy datasets and the requirement to destroy copies of disputed works can reshape model pipelines. Building auditability into data ingestion and curation is now a business imperative, not a back-office task, especially as plaintiffs and courts focus on the scale and source of training corpora.
OpenAI’s update targets a different risk surface: consumer safety for young users. Following a wrongful death lawsuit that alleges ChatGPT contributed to a suicide, the company announced parental controls and other safeguards. Over the next month, parents will be able to link accounts and set age-appropriate model behavior, disable memory and chat history, and receive notifications when the system detects signs of acute distress. Users will also get reminders to take breaks after extended use. OpenAI said it is continuously improving how its models respond in sensitive interactions and feels a deep responsibility to help those who need it most.
Under the hood, OpenAI disclosed a real-time router that selects between efficient chat models and reasoning models based on the conversation context. The company said it will soon begin to route some sensitive conversations, such as when the system detects acute distress, to a reasoning model like GPT‑5‑thinking, regardless of which model a person first selected. The review of these safety systems will run over the next four months, led by OpenAI’s Council on Well-Being and AI and the Global Physician Network. While the council will advise on product, research, and policy decisions, OpenAI stated it remains accountable for the choices it makes.
The technical and legal through line is clear. Anthropic’s settlement underscores the financial risk of unclear training data practices, measured in billions, while OpenAI’s product changes show that safety enforcement can be embedded at the routing layer, not just as content filters. Sensitive interactions can trigger a different class of model, and parental controls can disable memory and chat history by design. As several other copyright cases proceed and as consumer safety expectations evolve, the foundation model stack is being rebuilt to withstand scrutiny at both ends: what goes into the model and how it behaves in the hands of vulnerable users.
Conclusion: The immediate costs are large and the architectural changes are significant. From a historic copyright recovery claimed by plaintiffs to product-level safeguards for teens, the signal to founders and operators is to treat data provenance and safety systems as primary features of the roadmap.
