McKinsey just dropped its 2025 AI report. 1. Everyone’s testing, few are scaling. 88% of companies now use AI somewhere. Only 33% have scaled it beyond pilots. 2. The profit gap is huge. Just 6% see real EBIT impact. Most are still stuck in “experiments,” not execution. 3. The

Agency > Intelligence I had this intuitively wrong for decades, I think due to a pervasive cultural veneration of intelligence, various entertainment/media, obsession with IQ etc. Agency is significantly more powerful and significantly more scarce. Are you hiring for agency? Are

When building #ML/#genAI models, we often assume that expert-labeled data is consistent and reliable. But that’s not always the case. In radiology, for example, data labeling has a subjective component—annotations often reflect the clinician's perception rather than an objective

Another update to the HELM benchmarks (MMLU, Lite, AIR-Bench) with new model versions. We do see some movement near the top even with these "minor" versions updates. https://t.co/kJ9AXKzGF3 Claude 3.5 Sonnet (20241022) Gemini 1.5 Pro (002) Gemini 1.5 Flash (002) GPT-3.5 Turbo

Our latest work improves chest x-ray report generation with LLM alignment tools! We build a scalable preference fine-tuning pipeline to improve automated metrics + expert rad. win rates—all WITHOUT any radiologist feedback. Preference alignment w/o needing human preference. 1/3

If I finetune my LM just on responses, without conditioning on instructions, what happens when I test it with an instruction? Or if I finetune my LM just to generate poems from poem titles? Either way, the LM will roughly follow new instructions! Paper: https://t.co/Jk3EOtLJXF

This was a really fun project. Fine-tuning a model on "" => response produces a model that can do instruction => response What??

📢 Introducing HeadCT-ONE: Our new paper addresses a major gap in AI evaluation for radiology—capturing semantic equivalence. Using ontologies, we standardize medical terms, making AI-generated head CT reports more accurately comparable, even when phrasing differs.🧠✨
