Breaking: we release a fully synthetic generalist dataset for pretraining, SYNTH and two new SOTA reasoning models exclusively trained on it. Despite having seen only 200 billion tokens, Baguettotron is currently best-in-class in its size range. pleias.fr/blog/blogsyn...

“…you’re much better served as a student by getting a degree in an “irrelevant” subject that motivates you to put in real, high-quality work than by shuffling through something more relevant on a surface level doing only the bare minimum to meet the requirements.”

Choudhury and Kim et al., "Accelerating Vision Transformers With Adaptive Patch Sizes"

Transformer patches don't need to be of uniform size -- choose sizes based on entropy --> faster training/inference. Are scale-spaces gonna make a comeback?

Pro tip: For good Halloween vibes, use non-normalized RoPE on images larger than your training resolution and larger than the composite period of some of the RoPE-rotations. You might get scary ghost structures in your features.

If I ever leave this city, it will 100% be due to the price of housing rather than taxes.
Did New York's last big tax increase on the wealthy actually drive our millionaires to Florida?

No, absolutely not, says a new study.

“…on current trends the grid can grow sufficiently to accomodate all of these loads and some residential electrification as well, and do so at a rate of growth only about half of that which was seen between 1975 and 2000.”

btw what I did here was I took a data set of ChatGPT interactions collected in the wild and reversed the "assistant" and "user" tags. fine-tuned llama 8B on some of that data and gave it the ability to message you first. 😊

Lot's of work being done on columnar file formats lately. I count 5 new formats so far (Lance, Nimble, Vortex, FastLanes, F3).

It's definitely something we follow at LanceDB and it can be confusing to track. So here is my very biased head-canon (trying to stay positive)

Great thread
It's a great discussion because we all have different interpretation of what this means and what the consequences are.

Myself, I have absolutely no doubt that scaling works. If you have all the videos in the world and are able to train a model that can recall and merge any of them, then for sure...

I was reading Zen and the Art of Motorcycle Maintenance last night, so it’s a bit of a surreal dichotomy to compare Quality to this Slop post
I've written an essay reflecting on how I use the word slop and some theory of what distinguishes slop from spam and kitsch.

This week on Counting Stuff. Layoffs! I'm in search for a job now! It sucks but here we are!

Now's the ideal time to give me money in exchange for time or a project. Or if you just have leads in quantitative/data/researchy positions across NYC or remotely
