last week’s top stories

💻 Anthropic launches Claude Opus 4.5 as a coding powerhouse. Anthropic launched its latest model, Claude Opus 4.5, touting it as “the best model in the world for coding, agents, and computer use.” It smashed coding benchmarks and introduced features like an “endless” long-context chat for programmers. However, outside of coding and technical workflows its gains seem modest, suggesting Anthropic doubled down on a niche strength while leaving general performance largely unchanged. Great news if you live in VS Code, but for broader AI smarts it might not move the needle. Read more

🤔 DeepSeek V3.2 models arrive with big claims. China’s AI lab DeepSeek released two new reasoning-focused models, V3.2 and V3.2-Speciale, boasting open-source code and “GPT-5 level” performance. They emphasize better tool use and long-context reasoning, even achieving gold-medal scores on math and coding benchmarks. Coming after rival models from Google and OpenAI, this launch feels like catch-up; impressive on paper but arguably too little, too late. Read more

🛒 OpenAI adds shopping guide to ChatGPT, drawing mixed reactions. OpenAI rolled out a new shopping research assistant in ChatGPT that asks you questions and scours the web to recommend products. It turns the AI into a personal shopper that compares options, checks prices, and even ties into a checkout feature (just in time for holiday deals). It’s a nifty, consumer-friendly update, but some see it as OpenAI spinning its wheels with minor features while rivals wow the world with giant new models. Read more

🎶 Warner Music partners with AI startup Suno to license artist voices. In a landmark deal, Warner Music settled its lawsuit with generative music startup Suno and agreed to let Suno’s AI use the voices and likenesses of Warner’s artists (like Coldplay and Ed Sheeran) for user-made songs. The industry is cautiously cheering this “if you can’t beat ’em, join ’em” approach. Read more

📊 MIT study: AI could already handle 12% of U.S. jobs. New research from MIT finds today’s AI is technically capable of doing work equivalent to nearly 12% of the American workforce. Using an “Iceberg Index” that compares AI abilities to 1,000 occupations, the study shows AI can take on many routine tasks in finance, tech, healthcare and more (representing about $1.2 trillion in wages). The authors stress this doesn’t mean all those jobs will vanish overnight, but it’s a stark reminder of how much of the labor market is already in AI’s reach. Read more

🧠 OpenAI’s Ilya Sutskever says the era of simply scaling AI is over. In a rare interview, OpenAI cofounder (now at startup SSI) Ilya Sutskever declared that the “age of scaling” from 2020–2025 has hit a wall. Sutskever argues the next breakthroughs won’t come from 100x bigger models, but from new ideas and research insight. The future “age of research” will focus on novel algorithms (with all that compute now as our lab equipment). Read more

🎨 Flux.2 image AI debuts, aiming to dethrone Midjourney. Germany’s Black Forest Labs released Flux.2, a new text-to-image model suite geared for professional creators. It delivers 4-megapixel photorealistic output, handles multi-image inputs for style control, and even has an open-source core (its variational autoencoder) to avoid vendor lock-in. In a world dominated by a few big closed generators, Flux.2 is an intriguing challenger that’s open-ish and enterprise-friendly. Read more

🚀 White House launches ‘Genesis Mission’ to turbocharge AI science. The US government announced an Apollo-like initiative dubbed the Genesis Mission to unleash AI on federal science data. A new DOE-led AI platform will unite national lab supercomputers with vast troves of research data (from genomics to materials) letting AI agents design experiments and run simulations to accelerate breakthroughs. The goal is to shrink discovery timelines “from years to days” in areas like drug development, energy, and space. It’s a bold money move (some call it a dramatic science bailout) that bets big on AI to revitalize innovation. Read more

🤝 AWS goes big on “agentic AI,” even partnering with rival Google. Amazon’s cloud division used its re:Invent conference to unveil a wave of AI updates aimed at enterprises. The flashiest: Amazon Connect’s new agentic AI customer service bots that can autonomously handle complex calls using an advanced speech model. Amazon also announced a partnership with Google Cloud to enable seamless private networking between AWS and GCP (a once unthinkable alliance to please big customers). Read more

🇺🇦 Ukraine to build its own GPT-style AI, using Google’s open tech. Ukraine’s Ministry of Digital Transformation revealed plans for a homegrown large language model, developed with Google’s assistance as a backbone. Using Google’s open-source Gemma framework, they’ll train the AI on Google Cloud and then fully transfer it to Ukrainian infrastructure. The envisioned Ukrainian AI would serve both military and civilian needs, from aiding battlefield decisions to improving public services for 23 million daily users. Crucially, they’re also hardening it against cyberattacks (a must, given persistent Russian cyber threats). It’s a bold endeavor for a nation under siege, but if it succeeds, Ukraine could emerge from conflict with one of the most advanced national AI platforms anywhere. Read more

🖥️ Nvidia invests $2 billion in Synopsys to fuel AI-designed chips. In yet another big AI deal, Nvidia is taking a $2 billion stake in Synopsys, a leading chip design software company, as part of a partnership to build new AI-powered design tools. Basically, Nvidia wants to use AI to design the next generation of everything (chips for cars, data centers, you name it), and Synopsys’ tools are where a lot of chip blueprints begin. This adds to Nvidia’s recent shopping spree: they’ve thrown money into everything from OpenAI to a $5 billion chunk of Intel. It’s betting that vertical integration (and a few billion in strategic bets) now will keep it on top of the AI food chain for years to come. Read more

🧪 AI Research of the Week

Machine learning for risk stratification in the emergency department (MARS-ED): a randomized controlled trial
From Maastricht University Medical Center+ and Maastricht University

Jake’s Take: This study shows how far clinical AI has come and how far hospitals still have to go. The team built RISK^INDEX, a model that uses standard lab panels (plus age and sex) to predict 31-day mortality, then ran an open-label randomized trial in the Maastricht emergency department where 1,303 patients went through either usual care or usual care with the AI score on screen.

The model reached AUROC 0.84, while clinicians sat around 0.73 to 0.76 and classic scores like NEWS, APACHE II, and SOFA hovered near 0.65 to 0.75, yet physicians changed management in only 1 of 644 AI-arm cases and outcomes matched the control group.

The lesson is blunt: we already have models that see risk better than humans. The remaining bottleneck lives in interface design, trust, and clinical incentives, so future impact work in healthcare AI needs to treat UX and change management as first-class research problems (or these models will keep shining on paper and fading at the bedside).

and then, even more news…

🧬 Harvard’s new AI finds hidden disease genes in your DNA. Researchers at Harvard Medical School unveiled popEVE, an AI model that scoured human genomes and pinpointed 100+ genetic mutations likely to cause rare developmental disorders. Trained on evolution’s “tree of life” data, the system can rank gene variants by how damaging they are. In tests, popEVE solved decades-old medical mysteries, identifying 123 culprit genes for undiagnosed conditions (25 of which have since been confirmed by other labs). The team notes it’ll take more validation before this tool becomes a clinical mainstay. Read more
