Buzzworthy developments of the past few days.

• Would you wake us when you’re sure it’s a little less woke? Undaunted by the ridicule Google’s Gemini brought upon itself less than a month ago—female pope, Black Vikings, other history-bending howlers—Google is now touting the chatbot’s image-generation function for, specifically, clinical uses. “[W]e’re researching how a version of the Gemini model, fine-tuned for the medical domain, can unlock new capabilities for advanced reasoning, understanding a high volume of context and processing multiple modalities,” Google reports in a blogpost talking up various efforts the company is making with genAI for healthcare. The post is written by Yossi Matias, Google’s engineering & research VP. Read the whole thing.
   
• And in AI news from the very biggest of the Big Tech players (by market capitalization): Microsoft has hired two AI heavy hitters to launch and lead a new organization straightforwardly named Microsoft AI. The pair’s initial top tasks will be advancing Copilot and “other consumer AI products and research.” Mustafa Suleyman, co-founder of both DeepMind and Inflection, becomes EVP and CEO of the new arm. Karén Simonyan, co-founder of Inflection and key developer of AlphaZero, enters as its chief scientist. In a March 19 blogpost addressed to Microsoft employees, Microsoft CEO Satya Nadella tells his team: “We have a real shot to build technology that was once thought impossible and that lives up to our mission to ensure the benefits of AI reach every person and organization on the planet, safely and responsibly.”
   
• Samsung has its heart set on breaking Nvidia’s firm grip on the AI accelerator market. And while the South Korean technology powerhouse is at it, it will try to “restore itself as the world’s biggest semiconductor company.” The reporting is from a translation of reporting in the Seoul Economic Daily by SamMobile. The niche outlet quotes Samsung Semiconductor CEO Kye Hyun Kyung, who announced at a recent shareholder meeting that the chip will debut in 2025 with the name Mach-1. The exec says the product will be “an entirely new type of semiconductor—a semiconductor designed to meet the processing requirements of future artificial general intelligence.”
   
• GenAI can help pay down technical debt, aka ‘code debt.’ Whatever you call it, it’s what often results when software developers feel rushed and take shortcuts. Poorly written code is only one form of costly (albeit nonmonetary) “debt” that can result. There’s a higher risk of accumulating such debt “when applying AI models to an existing technology ecosystem, such as revising connectivities and integrating gen AI models while using an old stack,” Neal Sample, CIO of Walgreens Boots Alliance, tells CIO.com. On the other hand, if used appropriately, gen AI “could help eliminate old technical debt by rewriting legacy applications and automating a backlog of tasks,” explains CIO writer Bill Doerrfeld.

• Surefire safeguards are available to keep large language AI models from serving up health disinformation disguised as authoritative advice. The problem is that such precautious measures are only applied here and there (as opposed to everywhere). In a study published in The BMJ, researchers from Australia and the U.K. present these findings before concluding that “enhanced regulation, transparency and routine auditing are required to help prevent large language models from contributing to the mass generation of health disinformation.” Research paper here, news summary here.
   
• Well this is equal parts exciting and terrifying. Researchers have come up with an AI predictor for discerning a person’s receptivity to being vaccinated against COVID-19. The system applies its steely logic to “a small set of data from demographics and personal judgments such as aversion to risk or loss.” The quote is from the news operation at the University of Cincinnati, whose researchers worked with colleagues at Northwestern University to design the algorithmic mind reader. Read the coverage, which includes a link to the scientific study. Or do what I did and make up your mind to flee that AI like a startled deer.
   
• Know any digital health enthusiasts with the urge to innovate? Consider pointing them to an upcoming hackathon bearing the theme “Building High-Value Health Systems: Harnessing Digital Health and Artificial Intelligence.” Organized by the Harvard T.H. Chan School of Public Health, the event will run April 5 and 6 (a Friday and Saturday). It’ll offer three tracks—cardiovascular disease & diabetes, cancer and mental health. Participants need not travel to Boston. Details here.
