Olmo 3 is notable as a "fully open" LLM - all of the training data is published, plus complete details on how the training process was run. I tried out the 32B thinking model and the 7B instruct models, + thoughts on why transparent training data is so important simonwillison.net/2025/Nov/22/...

Olmo is the LLM series from Ai2—the Allen institute for AI. Unlike most open weight models these are notable for including the full training data, training process and checkpoints along …

Any really good actually insightful or helpful articles or resources on teaching/learning in the age of LLMs?

Can we infer chemical reaction networks from time series data? Can we observe concentrations of substances over time and infer which substances react with each other? Learn if (and how much) this is possible from Yong See Foo, @adrianazanca.bsky.social and JenniferFlegg arxiv.org/abs/2505.15653
Quantifying structural uncertainty in chemical reaction network inference
Dynamical systems in chemistry and biology are complex, and one often does not have comprehensive knowledge about the interactions involved. Chemical reaction network (CRN) inference aims to identify,...

I tried defining a simple ‘prompt script language’ that sort of works and is fun to play with gist.github.com/omaclaren/b5...

I’ve got some students who wanna play around with eg 70B open llms. Can’t run locally obvs. What’re their best options in terms of ease of use and cost? Mainly just running for now but also maybe fine tuning at some point

This came up recently but I’m not 100% sure how to think about it. Eg suppose you have a nonlinear function of two variables f(x,y) evaluated on a 2D grid. One apparently useful way to approximate it is to think of the values as entries in a matrix and use matrix factorisation. But why?

Idle stats thought — calling them confidence subsets/subintervals instead of confidence sets/intervals would more honestly indicate that the coverage guarantees hold with respect to some set of initial of values considered

A nice summary on the other site of RL self improvement by @ptrschmdtnlsn.bsky.social “we keep distilling what we conclude after a lot of thinking into what we conclude intuitively in a single step of thinking, which in turn improves what we conclude with a lot of thinking, and so on”
