Learning rate adjustment is a very important part of training. You can use the default settings, or you can tweak it. Currently the default is 3e-6, which is higher than EveryDream1 which was defaulted to 1e-6, based on the results of testing and the ability to use larger batch sizes. You should consider increasing this further if you increase your batch size further (10+) using [gradient checkpointing](#gradient_checkpointing).
