Migrate from Stability AI to Dedicated GPU: Savings Calculator
How much can you save by moving from Stability AI (Stable Diffusion API) to a dedicated GPU server?
Projected Savings
Stability AI charges per image through their API — ironic, given that Stable Diffusion itself is open source and runs freely on any capable GPU. At a typical £350/month spend:
- £261/month (75% reduction)
- £3,132/year in total savings
Savings by Current Stability AI Spend
| Current Stability AI Spend | GigaGPU RTX 3090 Cost | Monthly Savings | Annual Savings |
|---|---|---|---|
| £100/mo | £89/mo | £11/mo | £132/yr |
| £250/mo | £89/mo | £161/mo | £1,932/yr |
| £500/mo | £89/mo | £411/mo | £4,932/yr |
| £1000/mo | £89/mo | £911/mo | £10,932/yr |
| £2500/mo | £89/mo | £2411/mo | £28,932/yr |
| £5000/mo | £89/mo | £4911/mo | £58,932/yr |
GigaGPU pricing is fixed monthly. No per-token, per-image, or per-request fees.
Why Pay Per Image for an Open-Source Model?
Stability AI charges per image generation for API access to models that are freely available. Self-hosted SDXL or FLUX.1 on a dedicated GPU gives you unlimited generations for a fixed monthly fee. You also gain access to LoRA fine-tuning, ControlNet, and the full ecosystem of community extensions that API access restricts.
Unlimited Image Generation on Your Hardware
- Dedicated hardware: A full RTX 3090 server exclusively for your workloads. No sharing, no noisy neighbours.
- Recommended alternative: SDXL / FLUX.1 delivers comparable quality to Stable Diffusion API for most production use cases.
- Fixed pricing: £89/month regardless of how many tokens, images, or requests you process.
- Full control: LoRA training, ControlNet, custom pipelines, img2img workflows — the full ComfyUI or Automatic1111 ecosystem.
- Data sovereignty: Your prompts and generated images stay on your server. No content filtering surprises.
Migration Is Straightforward
- Audit current usage: Review your Stability AI usage — note image dimensions, model versions, and daily generation volumes.
- Select your GPU server: Based on your throughput needs, choose from GigaGPU dedicated plans starting at £89/month.
- Deploy your model: GigaGPU servers come with CUDA, Docker, and inference frameworks pre-installed. Deploy SDXL / FLUX.1 in under 15 minutes.
- Replicate your pipeline: Set up ComfyUI or A1111 with your existing workflows, LoRAs, and generation settings.
- Run parallel testing: Compare output quality between Stability AI API and self-hosted for your specific use cases.
- Cut over: Once validated, switch fully to your dedicated server and cancel your Stability AI subscription.
Full Model Access
Since Stability AI’s API serves the same open-source models you can self-host, image quality is identical. The only difference is throughput, which depends on your GPU hardware. An RTX 3090 generates SDXL images in 3-5 seconds, matching or exceeding API response times.
