New research highlights two different hurdles for medical AI: gathering the right information and weighing competing answers. Hx2Dx ARENA, a benchmark built from 1,000 New England Journal of Medicine cases, tests whether models can ask questions, examine a patient and review tests before diagnosing. All models performed worse in this step-by-step setting than when given the complete case upfront, although those asking more focused questions did better. A separate retrieval-based framework improved medical multiple-choice accuracy by surfacing concise, answer-specific evidence and the distinctions between options.
In physical AI, MBZUAI’s Institute of Foundation Models released PAN 2, an open 29-billion-parameter model that simulates the result of a scene and a text-described action as video. It generates video at 704 by 1,248 pixels and 24 frames per second for up to 20 seconds. In tests of 100 multi-step tasks, it completed 34% of full plans, the best result among six models tested, but most plans still missed a step. Separately, MemryX announced MX3+, targeting up to 10 times MX3’s peak compute and nearly 10 times its on-chip memory within the same low-power budget. Those are design targets pending validation; engineering samples are targeted for late 2027 and volume production for mid-2028.
OpenAI says more than 20,000 transitioning servicemembers and veterans claimed a free year of ChatGPT Plus over the past year. The company and its partners have run more than a dozen trainings for nearly 1,000 military-community members, covering uses such as job searches, interview practice and translating military experience into civilian résumés. OpenAI says further training is planned before year-end, with its Academy and community partners continuing support.
Google’s Gemini is at the center of a family’s concerns about AI and school safeguards. The parents of a 13-year-old allege that their daughter used Gemini on a school-issued Chromebook to plan her suicide and that repeated questions went unflagged for weeks. They say monitoring systems detected the activity only when it was almost too late and are working with the school on prevention steps. The claims raise questions about how schools monitor students’ use of AI tools.
Debate over AI investment also features in two business reports. Sixth Street CEO Alan Waxman says the firm is cautious because AI spending has reached unprecedented scale while unit economics and returns remain unclear, complicating lenders’ assessment of repayment and asset-value risks; he says the outlook differs somewhat for equity investors. A webcast covering markets after the Democrats’ midterm election sweep says stocks rose Wednesday, fell Thursday amid concerns about limits on AI data-center construction, then partly recovered Friday. Its hosts expect the AI boom to continue at a slower pace and cite October employment-report takeaways indicating AI is creating jobs so far.
Industry and consumer product updates round out the news. At the American Feed Industry Association’s annual conference in Rio Grande, Puerto Rico, attendees discussed AI for productivity, efficiency, sales growth and cybersecurity. A golf tournament and raffle raised $6,520, and AFIA set its 2027 Equipment Manufacturers Conference for Nov. 3–5 in Tucson. Reolink’s 12-channel 4K security system is now available at Costco, with eight wired cameras, AI detection for people, vehicles and pets, and local recording on a 4TB drive without monthly fees. Storage can expand to 16TB, and the system supports up to four additional battery-powered Wi-Fi cameras.

Hx2Dx tests how AI gathers clues before making diagnoses
Researchers introduced Hx2Dx ARENA, a benchmark of 1,000 clinical cases from the New England Journal of Medicine. In each simulated encounter, an AI model must ask questions, examine the patient, and review tests before making a diagnosis. The researchers tested open and closed source large language models and found that all performed worse than when they received the full case at once. Models that asked more focused questions did better, but the results show that AI still struggles to gather the right information for real clinical care.
A new framework helps AI spot the evidence that separates medical answers
Researchers developed a retrieval based framework to help large language models answer medical multiple choice questions. It finds evidence specific to each answer option and presents the key differences in concise prompts. Tests across multiple datasets and language models showed consistent accuracy gains. The framework also performed better than using retrieved evidence directly or asking closed source models for general hints, suggesting that focused evidence can help models compare competing choices.
Feed industry meeting explores AI for efficiency and security
Feed industry professionals met in Rio Grande, Puerto Rico, for the American Feed Industry Association’s annual conference. AFIA’s Leah Wilkinson opened the program with an update on AI under the current administration, followed by discussions of AI for productivity, efficiency, sales growth, and cybersecurity. A closing panel covered the opportunities and challenges of adopting AI in the feed industry. The golf tournament and Thursday evening raffle raised $6,520, and AFIA announced that its 2027 Equipment Manufacturers Conference will take place Nov. 3 to 5 in Tucson, Arizona.
MemryX targets major MX3+ performance gains for low power edge AI
MemryX AI announced the MX3+ inference accelerator on November 10, 2026, with design targets of up to 10 times the peak AI compute and nearly 10 times the on chip memory of MX3, within the same low power budget. The chip is intended for edge, industrial, and high density systems running larger models, including vision and language models. MemryX says a 16 chip setup is designed to deliver more than 1 POPS of peak compute and 2.16 GB of distributed on chip memory, while its Neural Compiler maps networks across accelerators. The company is seeking selected partners to test pre production hardware and software, targeting engineering samples in late 2027 and volume production in mid 2028; the announced gains remain design targets pending validation.
OpenAI reports veterans are using ChatGPT Plus for career transitions
OpenAI says more than 20,000 transitioning servicemembers and veterans claimed a free year of ChatGPT Plus in the past year. The company and its partners have also held more than a dozen trainings for nearly 1,000 members of the military community, with more events planned before the year ends. Veterans have used ChatGPT to organize job searches, practice interviews, explore career options, and turn military experience into civilian résumés. OpenAI says its Academy and community partners will continue offering training to help veterans and military families use their skills in civilian life.
MBZUAI releases open PAN 2 model for testing physical AI plans
The Institute of Foundation Models at MBZUAI released PAN 2 on November 10, 2026. The open 29-billion-parameter model takes a scene and a text action, then simulates the result as video. It can create video at 704 by 1248 pixels and 24 frames per second for up to 20 seconds, and its weights and code are available under the Apache 2.0 license. In tests on 100 multi-step tasks, PAN 2 completed 34.0 percent of full plans, the highest among six tested models, though about two out of three plans still missed a step.
Parents say school systems missed teen’s repeated suicide questions to Gemini
The parents of a 13-year-old girl allege that she used Google’s Gemini AI on her school-issued Chromebook to plan her suicide. They say her repeated questions about suicide went unflagged for weeks, and that school monitoring systems detected the activity only when it was almost too late. The incident has raised concerns about the use of AI tools in schools and whether monitoring can catch harmful activity. The parents are working with the school on steps to help prevent similar incidents.
AI job growth and investment limits lead this week’s economic webcast
The webcast examines a changing stock market after the Democrats’ midterm election sweep. Stocks rose on Wednesday, fell on Thursday amid concerns about limits on AI data center construction, then partly recovered on Friday. Hosts Elias and Ed discuss financial, political and physical constraints facing the AI race, and say they expect the boom to continue at a slower pace. They also share four positive takeaways from October’s employment report, including that AI is creating jobs so far, and Ed reviews “Tenzing.”
Sixth Street warns AI spending may outpace clear returns
Sixth Street CEO Alan Waxman says the firm is cautious about AI investments because the sector’s costs and economics keep changing. He says AI capital spending has reached an unprecedented scale, while investors still lack a clear view of unit economics and potential returns. That uncertainty makes it difficult for lenders to judge credit risk, including whether borrowers can repay and whether assets will hold their value. Waxman says the outlook differs somewhat for equity investing.
