Gemini 2.5 Flash-Lite is now stable and generally available for developers and enterprise customers! ⚡ When designing a Gemini model, we think a lot about the tradeoffs between quality, cost, and latency. Previously with 2.0 Flash-Lite we optimized for cost-efficiency over…
I recently joined @nudge as medical director. We're building a world-changing device, with the goal of precisely and non-invasively modulating brain function to improve the lives of as many people as possible.

🥁Introducing Gemini 2.5, our most intelligent model with impressive capabilities in advanced reasoning and coding. Now integrating thinking capabilities, 2.5 Pro Experimental is our most performant Gemini model yet. It’s #1 on @lmarena_ai leaderboard. 🥇
A guess: The uncertainty in science funding in the US will -already- have a huge affect on PhD admissions for engineering schools this cycle, even before funding reductions hit (if they do). I expect historically low class sizes in CS PhD programs. Not good for US AI leadership.
Science is the engine behind American prosperity. Government funded research led to many of the breakthroughs we use today in AI. AI may well supercharge scientific productivity and the way to take advantage of it is to increase investment in scientific research. Unfortunately…
New paper alert!🚨 What do LLM reasoning, diffusions, & jailbreaks have in common? 🤔 All exhibit critical windows📈--a sudden formation of distinctive features during sampling, e.g. correctness or toxicity. We present a unifying theory of critical windows for diffusion & LLMs.
📢📢 Happy to share that our paper on unlearning evaluations has been accepted to ICLR 2025 🇸🇬 📜: arxiv.org/abs/2406.17216 Thanks to my great co-authors @SethInternet @thegautamkamath @jimmy_di98 @ayush_sekhari @yiweilu

I've been thinking about Privacy & LLMs work for 2025 - here are 5 research directions and some key papers on privacy/memorization to get started: 🧵
You trained your model and then realized some of your data was bad/copyrighted - what can you do? Fear not, we have (some) answers! Check out this new work on *Un*learning by me + my collaborators. @smsampark @kris_georgiev1 @shivamg_13 @andrew_ilyas @aleks_madry @SethInternet
