-The above command trains an SAE for every _even_ layer of Llama 3 8B, using all available GPUs. It accumulates gradients over 8 minibatches, and splits each minibatch into 2 microbatches before feeding them into the SAE encoder, thus saving a lot of memory. It also loads the model in 8-bit precision using `bitsandbytes`. This command requires no more than 48GB of memory per GPU on an 8 GPU node.
