Small-scale study: 16 law professors were asked to judge short-answer Q&A practice materials written by one of the other 15 professors, or generated by an LLM (Gemini 2.5 Pro). They preferred the LLM materials in 75% of cases, with fairly strong inter-rater agreement. Has some…

Our fully open releases give researchers the data, code, checkpoints, and methods they need to inspect claims, reproduce findings, and advance new science. Read more about why that’s so important to us. ⬇️ allenai.org/blog/who-get...

AI Weekly's analysis →
  • Ai2 argues meaningful AI transparency requires not just open weights but training data, code, methods, checkpoints, evaluations, and documentation.
  • Post cites three studies enabled by open Olmo releases, covering clinical demographic bias, benchmark inflation, and how models reason about drug names.
  • Without that access, Ai2 warns, technical direction of the field risks becoming concentrated inside a small number of companies.

An interesting development on the local-models front: one of the largest U.S. law firms is going to start fine-tuning and hosting its own LLMs in-house.

finally some off-the-grid local AI

CrankGPT — fully offline, human-powered local AI squeezlabs.github.io
AI Weekly's analysis →
  • CrankGPT runs a full voice-interactive AI pipeline on a Raspberry Pi 5 with 8GB RAM, powered solely by a 20W hand-crank generator.
  • Cold-start to functional conversation takes roughly 30 seconds; time to first token ranges from 0.8 to 2.9 seconds depending on model size.
  • Memory bandwidth, not raw compute, is the primary bottleneck for on-device LLM inference, with DDR5 hardware achieving 29-58% faster token generation than DDR4.

Now published in open access! Your one-stop shop for the philosophy of language models. It's the spiritual descendant of our two-part preprint from 2024, fully updated. This should be particularly useful for anyone looking for an entry point into this rapidly growing field.

Kind of reassuring to read that one of the biggest current problems in ML for drug discovery isn't any kind of exotic new AI/ML problem but just, still, the difficulty of preventing data leakage from the test set.

Recent commentary

Underreported thing about Gemini (more than other LLMs I think) is that it's an ok replacement for Google Books, and fluidly multilingual. Like I can ask a question and request answers be based only on books by a specific academic (which are in Greek) and it will dig up relevant passages.

I like AI, but still, is this what I want to see at the Amtrak station

Noticing a pattern across departments that faculty are generally a lot more excited about AI than students, esp undergrad students.

Got a good 96gb-VRAM local LLM harness going and can't believe I used to just... put up with the garbage latencies that OpenAI/Anthropic/Google serve up.

There's a huge increase in single-author papers being submitted by early-career researchers in AI/ML. Leaving aside other issues, from a purely CV-maxxing perspective do these even help? I think on a hiring committee I'd give them mixed to negative weight in many cases.

A reason I've pulled back from reviewing for big AI conferences is a feeling that I'm doing unpaid supervision of other people's PhD students. Too many ppl submitting 10+ papers to a single conference where I doubt the prof whose name is on the paper has done a thorough review & revision themselves.

Not a strongly held opinion, but I'm a little skeptical of the recent LLM math results not really being compared against baseline search methods with similar compute budgets. Some of them are using pretty huge compute budgets!

An interesting thing about LLMs in Python is that they seem to broadly push code towards some kind of conventional wisdom about best practices, as judged maybe by whoever is setting up the posttraining recipes (I say "in Python" mostly because I notice that more strongly in Python).

Tip for people stuck in the Microsoft 365 ecosystem: the Copilot AI search sidebar is a huge improvement! Largely because almost anything is better than Outlook search (it won't find emails that have the verbatim search term in the subject!). But still, now there's working search. Ty AI boom.

A thing LLM coding sort of makes more feasible is making *smaller* personalized apps. Like instead of WMATA's big and annoying to use transit app, I'm trying out a custom little thing that just shows me the 2 bus lines I take. Lines hardcoded; stops hardcoded; no configuration; barely any interface.
