Question 1

How are distributed training costs calculated?

Accepted Answer

Total cost = (GPU price per hour × number of GPUs × training hours) × provider multiplier. Spot instances apply a 60–70% discount on the base GPU rate.

Question 2

Which GPU is most cost‑effective for large‑scale training?

Accepted Answer

H100 offers the highest throughput, but A100 80GB often provides the best balance of memory and cost. L4 and T4 are budget‑friendly for smaller models.

Question 3

How much can I save using spot (preemptible) instances?

Accepted Answer

Spot instances typically reduce GPU costs by 60–70%, but they can be interrupted. For fault‑tolerant training, spot savings are substantial.
