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...

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.

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.
