Welcome back to Week in Review. This week, we’re exploring the DOJ telling Google to sell off Chrome to break up its monopoly, OpenAI accidentally deleting potential evidence in The New York Times’ copyright lawsuit against it, and how AI companies are using TikTok brainrot for study tools. Let’s do this.

The U.S. Department of Justice argued that Google should divest its Chrome browser to help break up the company's illegal monopoly in online search. District Court judge Amit Mehta ruled in August that Google was an illegal monopoly for abusing its power over the search business, and the DOJ's latest filing suggests that Google's ownership of Android and Chrome pose "a significant challenge" to apply remedies for making the search market competitive.

Anthropic has raised another $4 billion from Amazon and agreed to make Amazon Web Services the primary place it'll train its flagship generative AI models. The company is working with Annapurna Labs, AWS' chip-making division, to develop future generations of Trainium accelerators, custom-built chips by AWS for training AI models. That adds a new $4 billion infusion from Amazon, which now stands at $8 billion.

Lawyers for the publishers claim that in The New York Times and Daily News' copyright lawsuit, OpenAI accidentally deleted potential evidence. As part of the suit, OpenAI agreed to provide two virtual machines so that counsel could perform searches for their copyrighted content in its AI training sets. But in a letter, attorneys for the publishers say that OpenAI engineers erased all the publishers' search data stored on one of the virtual machines.
