Averaging model weights seems to help across textual domains as well, see Branch-Train-Merge: Embarrassingly Parallel Training of Expert Language Models and Scaling Expert Language Models with Unsupervised Domain Discovery. I wonder if the two types of averaging (across hyperparameters and across domains) can be combined to produce even better models.

That’s appreciated!

Research into efficient optimization techniques seems pretty important given the scale of LLMs these days. Nice to see a second-order approach that achieves reasonable wall-clock improvements.

If there isn’t any discussion on reddit (no discussion in this case), I don’t see a reason to link to reddit; you can just link to the project page. That said, if you think there is important discussion happening that is helpful for understanding the paper, then use a teddit link instead, like:
