With EC2 instances you generally know what you are getting (instance type corresponds to specific CPU), although there's a multitude of ways to pay/reserve/prepay/etc which makes pricing very complicated, and pricing further varies by region (I used the lowest cost US regions). In the 1Y/3Y reserved prices listed, there is no prepayment included - you can lower them a bit further if you do prepay. The spot prices vary even more, both by region and are updated often (especially for newly introduced types), so you'd want to keep track of them.

We could just delete this assertion. Or we could just set the model to eval mode. Contrary to the name, it has nothing to do with whether the model is trainable or not. Eval mode just turns off train time behavior. Historically, this meant no dropout and using stored batch norm statistics rather than per-batch statistics. With modern LLM’s, this means, well, nothing—there typically are no train time specific behaviors. requires_grad controls whether gradients are tracked and only the parameters passed to the optimizer are updated.。业内人士推荐新收录的资料作为进阶阅读
