Hey, I am one of the co-authors of the post. So the training data for ViGGO has about 5.1k rows which we trained with a block size of 512 (you can lower the block size if you want but we didn't do so because it was just easier to not change code :)). On 16xA10Gs for 7B it took ~15 min per epoch and on 13B it took ~25 min per epoch. So the on-demand cost per epoch is ~$7.2 for 7B and ~$12 for 13B. This is based on the time only spent on the training part and does not take into account the cluster startup time and shutdown time.
