Compare every managed API and self-hosted GPU for AI image generation. Enter your monthly volume and see exactly when self-hosting beats managed APIs — with break-even analysis.

Building a SaaS with personalized LoRA models? Calculate VRAM constraints, GPU count, and the real monthly cost of serving 5 to 500+ LoRAs — DIY vs Runflow vs per-image API.

Warm generation times across fal.ai, Replicate, Together AI, Runware, and Runflow. P50/P95 per model — the actual latency your users experience, not cold start.

ComfyDeploy vs ViewComfy vs Runflow vs DIY RunPod — compare pricing, custom nodes, cold starts, and SLA side by side. Filter by your use case.

P50/P95 cold start times across 8 providers including Runflow. Calculate the real latency impact on your users and the cost of keep-warm strategies.

Model → GPU and GPU → Models. Estimate memory for any model, resolution, batch size, and quantization. See rental prices and when managed APIs beat self-hosting.

Images per second and images per dollar across every major GPU — RTX 4090 to H200. Sort by raw throughput or cost efficiency. Find the best GPU for your workload.

Generation + upscaling + background removal + face restoration: calculate the real per-image cost of your full pipeline. API vs self-hosted comparison with break-even analysis.

How much does it cost to train a LoRA on Flux Dev, SDXL, or SD 3.5? Enter your steps and GPU — get exact cost and training time across RunPod, Modal, Lambda, and Vast.ai.

Can you use Flux Dev, SDXL, or Midjourney commercially? The complete license reference for every major AI image model — commercial use, fine-tuning rights, output ownership.

Enter your real cost per image and target market — get suggested pricing tiers, break-even analysis, and competitor benchmarks against Midjourney, Leonardo, and Adobe Firefly.

The complete feature comparison of every major Stable Diffusion UI. Filter by use case — production API, fastest GPU, professional canvas, or quick experimentation.
