FAQ

What's the cheapest way to generate 1000 images monthly? RunPod RTX 3090 at $0.22/hour. 1000 512x512 images at 8 seconds each = 2.2 hours, $0.48 total.

Should we use an API or self-host? API: Under 100 images/month. Self-host: 1000+ images/month.

Can we reduce Stable Diffusion quality to save cost? Yes. 20 steps vs 50 steps = 2.5x faster with 10-15% quality reduction.

What's the latency with GPU cloud providers? RunPod: 10-30 seconds (includes cold start). Lambda/CoreWeave: 5-15 seconds persistent.

Do we need production GPUs for Stable Diffusion? No. RTX 3090 sufficient for 512x512. A100/H100 needed for batch processing or 768x768+.

Can we use RTX 4090 on cloud? Yes, RunPod has RTX 4090 at $0.34/hour. Better price-performance than consumer purchase.
