Benchmark scores influence which AI models get funded, bought, and regulated. Two new studies from Stanford researchers and collaborators, supported by Stanford HAI, ask whether those tests measure what they claim to. Read more: hai.stanford.edu/news/the-te…

It is important for AI to understand our long-term goals and help us *achieve* these goals. Important work from a great PhD student I work with @sapkotashardul_. Supported by @StanfordHAI and @HPI_DE. Check it out!
AI systems understand what we’re doing right now.
What if they could also understand what we’re working toward long term and why it matters to us?
We built Tempo to connect computer use to long-term goals, with inferences you can inspect and correct.

Parker Ruth, a PhD student I advise @Stanford, devised an improved method to analyze heart signals. His Bayesian pulse deconvolution method helps extract accurate information from health device biosignals. Read about it in our npj Digital Medicine paper. hci.st/bayesianpd

Downloading a model is increasingly easy. Understanding how it was made — or changing it at its root — is another matter.
“Open weights answer ‘Can I run this?’ Open source answers ‘Can I trust this, improve it, and build the next thing on top of it?’ Right now almost everyone is answering the first question but nowhere close to the second.” Stanford HAI Denning Director @landay, cited in The Register: theregister.com/columnists/2…

Monday, 10 am PT: Rob Reich, @Diyi_Yang, and @AmyZegart open Prompt Response, our new faculty series. On the table: Is AI an existential risk, can the pace slow, and who writes the rules?

From ImageNet for computer vision to HELM for LLMs, Stanford’s AI team has been at the forefront of open source evaluation of AI. @StanfordHAI, home to @StanfordAILab, supports researchers at the forefront of AI model benchmarking. It takes a village to shepherd great technology!
I propose Stanford NLP as an independent third-party evaluator under @DarioAmodei’s 3 step plan. For important parts of the work, universities would be better than any other organization (see below 🧵👇), and, of university groups, @stanfordnlp would be the best one to choose. 😊

Honored to lead this merged institute with a new vision and excited to have @drfeifei and John Hennessy advise me.
Big news! @Stanford is merging @StanfordHAI & Stanford Data Science into a single institute, led by @landay. Continuing under the HAI name, the institute seeks to advance AI & data science for discovery, transform education, and shape AI’s societal impact: news.stanford.edu/stories/20…

Best paper honorable mention at CHI — instantly adaptive objectives for LMs as you use your computer
Most of what I actually need help with, I never think to tell a model. But why is it on me to remember?
Our new paper asks: what if AI could proactively specialize to individuals and the tasks they’re carrying out at this very moment? 🧵

Wake up #CHI2026 & get to the conference. See the important & thought-provoking work on ontological multiplicity & personal sensing—pushing us to rethink what “the human” means in design. Come support my star advisee Nava Haghighi in P1-133 at 9AM.

Great work on an app for fitness behavior change led by @mjoerke (PhD student advised by @EmmaBrunskill and me). Work supported by @StanfordHAI and the @H_P_Foundation in collaboration with @HPI_DE. You should download the Bloom app when it is ready or read the paper now!
I’m excited to share that Bloom, where we ran a four week study on LLM health coaching, just won a Best Paper Award at CHI! 🏆

At @NVIDIAGTC, @StanfordHAI's James @Landay said we're amid a major shift in human-computer interaction. Current text/voice AI is "just a blip" and he envisions a future of multimodal agents that anticipate user needs through voice, gesture, and context: nvidia.com/en-us/on-demand/s…
