Chicago Tribune sues Perplexity | TechCrunch

On Thursday, the Chicago Tribune filed a lawsuit against the troublesome AI search engine, alleging copyright infringement. The lawsuit, spotted by TechCrunch, was filed in a federal court in New York.

The Tribune alleges that its lawyers contacted it in mid-October with concerns about whether the AI ​​search engine was using its content, according to the complaint. Troubled’s lawyers responded that it had not trained the models from the Tribune’s work but that it could “provide illogical summaries of facts,” the lawsuit claims.

However, the Tribune’s lawyers argue that the problem is providing the Tribune’s content orally.

Interestingly, the paper’s advocates are also blaming recovery-arrested generation (RAG). RAG is a method used to limit bias by using only one valid or verified data source to model. The Tribune contends that the concern is using the newspaper’s content in its RAG system, deleted without permission. In addition, it alleges that the problematic Comet browser is bypassing the paper’s paywall to deliver detailed summaries of these articles.

The Tribune is one of 17 news publications of the Madinos Group and Tribune Publishing. He was prosecuted OpenAI and Microsoft to model training material in April. This suit is ongoing. Another nine from these publishers Filed a case Also in November, the model maker and its cloud provider.

While the creators have filed Many lawsuits Using their work to train models against modelers, we need to see whether courts also weigh in on RAG’s legal obligations.

Dow Jones is Also the case. Last month, while Amazon didn’t sue, it threatened to send a cease-and-desist letter over its purchase of the AI ​​browser.
