My Claude found a critical zero day vulnerability in the Code of Hammurabi, unnoticed by developers for 3,779 years.

My attention span is worse than ever, agents have made it much harder for me to focus on any given thing

Introducing AstaBrief 8B, an open model that turns complex research questions + literature excerpts into cited reports. Run it locally on your own hardware, with open weights + training data you can inspect & build on. 🧵 🤗 Download: huggingface.co/allenai/AstaB…

Whenever I see a model top this chart, it's normally a bit of a red flag. Would love to be proven wrong!
As expected, unfortunately the only bad thing about the new Opus is it's a token-gobbling monster. Uses the most tokens per Intelligence Index task of any model benchmarked. The price cut makes more sense here!

"stochastic parrot" was a mimetically-fit cognitive virus that spread from 2021-2025; it temporarily blinded many gifted people to the nature of AI progress, burning up crucial years in which they could have helped think through the response to the situation.

Replying to @PoliticalKiwi
... do we need to start publishing graphs of indicators of AI impact on the world that show no change. We could publish a lot of those. Here are some (very vibe coded) examples:

We have evidence that 1) AI agents are very good at improving software used to train AI 2) LLMs can be superhuman in many domains These do not combine to AI will be so powerful it will kill us in N years. We're forecasting inevitable saturation and unknown future breakthroughs.

Here is the grumpy blog post that @SergeyFeldman and I wrote 13 years ago when @finkd invaded NeurIPS to buy up all the researchers: explainmydata.blogspot.com/2… Everything we were worried about happened almost immediately but the field also made prev unimaginable progress

Today we're introducing a preview of TutorMoments, a framework that measures whether AI tutors can make one of the hardest calls in teaching: when to step in and help a student, & when to hold back and let them do the heavy thinking. 🧵

Includes a section on my flailing attempts to port MHCflurry from TensorFlow to PyTorch, which was mercifully finally dragged across the finish line by a combination of Claude Code and Codex in MHCflurry 2.2.0 (with @timodonnell & @SergeyFeldman)
Coding agents are helping scientists spend more time advancing research, taking on everything from routine maintenance and targeted optimization to complete redesigns and new systems. While agents can reliably execute on ambitious projects, researchers must still define the scientific questions, verify results, and take a stance on long-term ownership.

Deep search is also more conversational – better with follow-up questions, less rigid about phrasing – & can summarize what it found. It takes a bit longer, but it's built to be more reliable—try it on your hardest questions.

Late 2020s going to be full of breakthroughs communicated as tweets like “lol fine tuned SlopCoder-V7 and it proved P=NP” with a link to fully correct alien math

Deep conversation about the specs of the next pretraining run on our new B300 cluster. What do you want to see in a future Olmo release? With @lambdaviking @RenZhongzheng @TaoTianhua @yashassamaga @jowenpetty (I am hiring Sr. REs)

On might feel that the AI coding era diminishes the value of a library like @scikit_learn, as coding is easy. It's the reverse: one needs reliable building blocks, and fighting with Claude for eg reliable convergence of LogisicRegression takes energy, expertise, and tokens

It is not every day that I can tell you about a new explanation for the origin of the universe -- and the origin of time itself -- that is not complete bogus. But recently physicists have come up with one that works because it removes the problem of quantum gravity.

Today we’re releasing OlmoEarth v1.1. It’s 3x cheaper to run than v1 while delivering the same state-of-the-art performance—and fully open. 🧵
