After more than a year-and-a-half of intense spectacle and legal wrangling, Luigi Mangione appeared in a federal courtroom in New York on Friday as rumours swirled that he may plead guilty. The 28-year-old, accused of shooting dead UnitedHealthcare chief executive Brian Thompson on a Manhattan street in December 2024, arrived wearing a beige prison uniform with a white T-shirt underneath. His feet were shackled and he held his hands behind his back, although US marshals had not handcuffed him.

Plus: Nvidia has secured $500 billion from Wall Street for AI infrastructure. Nine years after Google researchers introduced the transformer, this family of neural networks has become the engine inside every major large language model. But transformers are starting to show their age. As LLMs get bigger and better, transformers have become a bottleneck. Their dense attention mechanism becomes increasingly expensive as the amount of text grows, and they're not great at keeping track of a lot of information at once. Here are four new ideas for how to solve the transformer problem --innovations that could change LLMs for good, making them faster, far more efficient, and (maybe) even smarter.

AI push is putting banks at mercy of tech firms, warns Moody's The rating agency Moody's has said the race to adopt AI is putting big banks at the mercy of a small group of Silicon Valley firms, leaving them vulnerable to widespread outages and price gouging by profit-hungry tech bosses. The financial sector's efforts to integrate AI into day-to-day operations will eventually cut costs and increase revenues across the City and Wall Street, Moody's said. But that will require "substantial investments", and with so many rivals racing towards the same goal, many of those benefits will end up being "competed away". AI will also create bigger risks around data privacy, cybersecurity, fraud and so-called "deposit flight", as well as an overdependence on a small number of tech firms, the rating agency warned. That will raise concerns for bosses across the financial sector. More than 75% of City companies now use AI, according to a UK Treasury select committee report published in January, with insurers and international banks among the biggest adopters.
