Introducing PaperQA2, the first AI agent that conducts entire scientific literature reviews on its own. PaperQA2 is also the first agent to beat PhD and Postdoc-level biology researchers on multiple literature research tasks, as measured both by accuracy on objective benchmarks

The beneficial effect of prestroke physical activity on activities of daily living (ADL) limitations after stroke is stronger than its effect in matched adults without stroke followed for a similar number of years. Matt Boisgontier

‼️"o1-preview demonstrates superhuman performance in differential diagnosis, diagnostic clinical reasoning, and management reasoning, superior in multiple domains compared to prior model generations and human physicians." And this is using vignettes, not multiple choice.

Education need to be completely restructured with the integration of AI. Every student should have access to a personal AI teacher. Higher education must also fully embrace AI & become 10 times more affordable. The impact of AI on education will be unimaginably transformative!

Insane we are now casually chatting about AI systems that can do all human work in 2-3 years and it’s barely registering in the minds of most people. This isn’t a schizopoast, or a grift, or whatever. It’s just true.

In September, 2024, physicians working with AI did better at the Healthbench doctor benchmark than either AI or physicians alone. With the release of o3 and GPT-4.1, AI answers are no longer improved on by physicians. Also error rates appear to be dropping for newer AI models.

👀Using an autonomous agent based on o3-mini and GPT-4.1, a team from Harvard, MIT & other institutions reproduced and updated an entire issue of Cochrane Reviews in two days… saving 12 person-years of work! The AI reviews captured more papers & were more accurate than humans.

A new study from OpenAI & Penda Health shows an AI copilot (GPT-4o) cut diagnostic errors by 16% and treatment errors by 13% across 40K+ live visits. First real-world, prospective evidence that LLMs can reduce clinical errors -- safely and at scale

Yeah, I'm just watching OpenAI 's newly released ChatGPT Agent power through my Qualtrics survey. I have thoughts about the future of human subject research. #artificalintelligence #LLM

Today I got the best peer review of my career (I’m a physicist with 150+ publications, Science, PRL). It was from GPT-5 Pro on a paper draft I’m writing. We’re entering a new era of science.
