What are you trying to run?
Here are some common tools and the GPU specs they usually need:
Tool | Recommended GPU | Notes |
Fooocus | 1x RTX 4090 | Smoothest experience with 24GB VRAM |
Stable Diffusion | 1x RTX 3090 or better | Needs ~16GB VRAM+ for full models |
InvokeAI / AUTOMATIC1111 | 2x RTX 4090 | For faster batch processing |
ComfyUI | 1x RTX 4090 or higher | Works well with large workflows |
Tip: Choose the lowest configuration that runs your model comfortably. You can always scale up later.
What if you don’t know what to pick?
Start small and test.
Use 1x RTX 4090 to get going
Monitor VRAM usage using
nvidia-smiIf you hit limits or run into crashes, consider upgrading to 2x
How to change configuration later
You can’t resize an instance directly, but you can:
Stop or terminate the current instance
Spin up a new one with a higher configuration
Reinstall your app or transfer your data if needed
Note: Save your model/data files before terminating an instance!
Want to go faster?
More GPUs = more parallelism. Use 2x configs if you:
Run large prompts or batch generations
Train or fine-tune models
Need lower latency for interactive work
