the best cloud GPU for fine-tuning an LLM costs about a dollar — here's the one to rent and why

Fine-tuning sounds expensive until you realize you can rent the perfect GPU for it by the hour. For small models a 4090 does it for pennies; for…

The short answer

For fine-tuning LLMs in the cloud, rent by model size: an RTX 4090 (~$0.34/hour) handles QLoRA fine-tuning of 8B models for under a dollar per run, an A100 80GB (~$1.19/hour) handles larger models…

8B QLoRA: a rented RTX 4090 (~$0.34/hr) — under a dollar per run.

Larger models / full fine-tuning: an A100 80GB (~$1.19/hr).

70B+ fine-tuning: A100 or multiple GPUs — bigger memory needed.

QLoRA keeps it cheap — ~14GB VRAM for 8B, so mid-range GPUs suffice.

Rent, don't buy, unless you fine-tune constantly — see fine-tuning cost.
