Recompute the forward pass activations during the backward pass instead of caching them, saving a massive amount of VRAM at the expense of minor CPU overhead.
: Tests multi-step mathematical reasoning capabilities.

When a model's weights, gradients, and optimizer states exceed the memory of a single GPU, distributed training becomes mandatory. Memory Footprint Breakdown For a model with parameters using AdamW optimizer in 16-bit mixed-precision: Gradients: Optimizer States: 12N12 cap N
The key sections include:
The vast corpus of text used to teach the model language. 3. Step-by-Step Implementation Process Phase 1: Data Preparation (The Foundation) You cannot build a good LLM without quality data.
A measure of how well the model predicts a sample. Lower is better.
