ChatGPT, the wildly popular AI chatbot, faced a significant outage on Tuesday, leaving users frustrated and unable to access its conversational capabilities. Over 1,500 reports flooded Downdetector, as the platform displayed error messages and failed to respond to queries. The disruption comes on the heels of OpenAI’s announcement of reaching $10 billion in annual recurring revenue, a staggering leap from last year’s $5.5 billion. Despite the impressive growth, the company reported a substantial loss of approximately $5 billion in the previous year. The outage coincides with the recent release of Advanced Voice, an update for paid users promising enhanced intonation and more natural interactions.

Scientists at Berlin’s Charité University Hospital have developed an AI model capable of identifying over 170 tumor types from all human organs. The model, called crossNN, focuses particularly on difficult-to-diagnose brain tumors. It analyzes epigenetic characteristics of tumors, providing highly accurate diagnoses without the need for invasive surgery in some cases. The AI achieves 99.1% accuracy for brain tumors and 97.8% accuracy across all tumor types. Researchers plan to conduct clinical trials across Germany to further test crossNN’s accuracy before potentially introducing it into routine cancer care. 

Nvidia’s newest chips have significantly improved the efficiency of training large artificial intelligence systems. According to data released by MLCommons, the number of chips required to train large language models has decreased dramatically. Nvidia’s Blackwell chips are more than twice as fast as their previous generation Hopper chips on a per-chip basis. The data shows that 2,496 Blackwell chips completed a training test in just 27 minutes, while it took over three times as many previous-generation chips to achieve a faster time. 

ABBA’s Björn Ulvaeus is crafting a new musical with the assistance of artificial intelligence. At 80, the legendary songwriter announced during SXSW London that he is nearly three-quarters through the creative process. He describes AI as a tool that extends his creative mind, helping break through tough blocks. The Swedish musician acknowledges the tool’s limits, noting it often produces unusable lyrics yet occasionally offers sparks for new ideas. His journey with cutting-edge technology continued after ABBA’s pioneering avatar show Voyage. Ulvaeus also champions fair compensation for artists as AI systems benefit from their work. The project arises from his ongoing work with Pophouse Entertainment

Vanderbilt University Medical Center researchers have developed two innovative AI technologies to improve cancer care. The first, MSI-SEER, predicts microsatellite instability-high status from pathology slides, potentially identifying more patients who could benefit from immunotherapy. The second is a 3D imaging tool that provides detailed tissue analysis at the subcellular level. These advancements demonstrate how VUMC is using AI to address various medical needs. The 3D imaging technology has applications beyond cancer diagnostics, including drug development and organ transplant assessment.
