"The Principles of Diffusion Models" by Chieh-Hsin Lai, Yang Song, Dongjun Kim, Yuki Mitsufuji, Stefano Ermon. arxiv.org/abs/2510.21890 It might not be the easiest intro to diffusion models, but this monograph is an amazing deep dive into the math behind them and all the nuances

The Principles of Diffusion Models

The main ingredient that led to GRPO's performance leap is the calibration of the reward/value via multiple rollouts per prompt. Let me elaborate on what I mean by that and a cheaper way of doing it offline.

To understand PPO, GRPO, or any policy-gradient algorithm, you first need to understand REINFORCE. I’ve written my notes here.

New video on the details of diffusion models: youtu.be/iv-5mZ_9CPY Produced by Welch Labs, this is the first in a short series of 3b1b this summer. I enjoyed providing editorial feedback throughout the last several months, and couldn't be happier with the result.

Diffusion models have analytical solutions, but they involve sums over the entire training set, and they don't generalise at all. They are mainly useful to help us understand how practical diffusion models generalise. Nice blog + code by Raymond Fan: rfangit.github.io/blog/2025/op...

Any intuition on using max_period=10k for t sinusoidal PE in, e.g, Flux? Since t enters via AdaLN and range is fixed, would linear interpol. two high dim vec work too? Does PE 10k make it easier to distinguish small t and harder for large t? Maybe @sedielem.bsky.social @stefanabaumann.bsky.social

Workers are not asking to get rich. They just want to afford three meals a day. In the richest country in the history of the world, no one should work for starvation wages. It is time to raise the disgraceful $7.25/hr federal minimum wage to a living wage of AT LEAST $17/hr.

I think the problem with visual art is that you see it immediately. Then you move on to the next piece, and once again, you’ve taken it in within seconds. It’s like opening a book, reading a few sentences here and there, and then closing it. 1/2

OpenAI doesn't want this dataset. Any company that wants Bluesky data will press a button and go get all posts on Bluesky. The very design of the website makes that trivial to do. This doesn't help OpenAI *at all*.

I attended an exhibition of Akseli Gallen-Kallela (1865–1931), and aside from the fact that his paintings are magnificent, it’s incredible how his women are more emancipated, full of character, and less subordinate to men compared to other artists of his time and even later.

I remember Jack Gallagher (MJ) saying that rectified flow is just slightly better than EDM. The PGv3 paper says they still use EDM. Is there any consensus on whether they’re ~the same or if one should switch to flow matching?
