Models
Learning Rate
The hyperparameter that sets how large a step the optimizer takes when it updates weights from each gradient.
In depth
The hyperparameter that sets how large a step the optimizer takes when it updates weights from each gradient. Too high and training diverges or the loss spikes; too low and training crawls or stalls. Most LLM training changes it over time with a schedule, commonly a short warmup followed by cosine or linear decay, which PyTorch exposes through its learning rate schedulers. It is usually the first setting to tune when a fine-tune misbehaves.
