Choose a GPU by Use Case: 8 Common Workloads

GPU rental optimization differs drastically across use cases: fine-tuning, image generation, video rendering, and inference — Data updated: 2026-10-26

Not sure which GPU to rent? Start from what you actually need to do. Each scenario below lists recommended models, the current lowest price, and an estimated cost for one task — prices refresh hourly.

Fine-tune a 7B model

LoRA / QLoRA fine-tuning for 7B~13B models: VRAM requirements, recommended GPUs, and the real rental cost of one training run

As low as ¥0.63/hour

LLM inference deployment

Online inference / API serving: throughput-first or cost-first, and which GPU fits your concurrency

As low as ¥0.87/hour

AI image generation (SDXL / Flux)

Stable Diffusion, Flux and ComfyUI: which card renders fastest with the lowest cost per image

As low as ¥0.63/hour

Video generation

ComfyUI / Wan / video diffusion: VRAM-hungry workloads where the wrong card means instant OOM

As low as ¥0.87/hour

3D rendering

Blender / C4D / Octane stills and animation: multi-GPU scaling versus single-GPU value

As low as ¥0.63/hour

Students / getting started

Coursework, your first demo, learning LLMs: get an environment running for as little as possible

As low as ¥0.63/hour

Train a 70B model

Pre-training / full fine-tuning of 70B: multi-GPU 80GB is mandatory — how to estimate cost and where it's cheapest

As low as ¥5.15/hour

Multi-GPU / clusters

Multi-node training: when to scale out, and the hidden costs of multi-GPU

As low as ¥0.87/hour
