**TLDR:** Gradient checkpointing'in seçim ağacı: per-layer mı, segment-based mi, custom selective mi? Re-entrant vs non-re-entrant farkı, torch.utils.checkpoint vs HF Trainer kwargs, selective checkpointing (sadece attn'i checkpoint et, FFN'i değil). RTX 4090 + Llama 3.1 8B üzerinde 5 strateji bench'i.
