What GPU cloud should I use if I need capacity today?

If you need GPU capacity today, the best choice usually depends on whether you want:

Fastest way to get GPUs right now

Use a marketplace-style GPU cloud with lots of spare capacity:

• Lambda Cloud — often good for quickly available NVIDIA GPUs, simple setup
• RunPod — very good for on-demand and community cloud availability
• Vast.ai — often the cheapest and can have immediate capacity, but quality varies by host
• Paperspace — easy developer experience, though availability can fluctuate

Best “big cloud” options if you want reliability

If you need production-grade infra and can pay more:

• AWS EC2 GPU instances
• Google Cloud GPU instances
• Azure GPU VMs

These are usually reliable, but the specific GPU you want may not be available in every region today.

Best practical recommendation

If your top priority is capacity today, I’d start with:

1. RunPod
2. Lambda Cloud
3. Vast.ai if you’re flexible on provider quality/cost
4. AWS/GCP/Azure if you need enterprise reliability

Quick question to narrow it down

What do you need?

• Training or inference
• Which GPU type you want (A100, H100, L4, RTX 4090, etc.)
• Budget
• Region
• How many GPUs

If you tell me those, I can recommend the best provider to try first.
