Image Gen API: Cost at 10K Images/Day
What does it cost to run image gen api at 10K images/day? Self-hosted dedicated GPU vs API provider pricing.
Pricing Comparison at 10,000 Daily Images
| Provider | Monthly Cost | Pricing Model | vs GigaGPU |
|---|---|---|---|
| GigaGPU (RTX 5090) | £179/mo | Fixed | — |
| Stability AI API | £1500/mo | Per-images | 88% cheaper with GigaGPU |
| Replicate SDXL | £1200/mo | Per-images | 85% cheaper with GigaGPU |
| RunPod Serverless | £420/mo | Per-images | 57% cheaper with GigaGPU |
300,000 Images a Month for £179
Ten thousand images per day means 300,000 per month. Stability AI’s invoice for that volume: £1,500. An RTX 5090 on GigaGPU: £179. That £1,321 monthly gap compounds to £15,852 in annual savings — enough to fund a junior developer’s salary in some regions.
Even the cheapest serverless option, RunPod at £420/month, costs 2.3x more than dedicated hardware. And serverless introduces cold-start latency that degrades user experience in real-time applications.
At 10K images/day, every penny per image matters. On GigaGPU, each image costs £0.0006. On Stability AI, £0.005. That is an 8.3x difference in unit economics that defines whether your image-heavy product is profitable or perpetually underwater.
Why Dedicated Hardware at 10K/Day
- Throughput certainty: The RTX 5090 generates 10-15 images per minute at 1024×1024. You clear your daily quota in 11-17 hours, leaving headroom for spikes.
- Pipeline customisation: Deploy img2img, inpainting, and ControlNet workflows alongside standard generation. API providers charge separately for each feature.
- Batch scheduling: Run overnight batches for catalogue imagery. The GPU works while your team sleeps — free compute hours that APIs charge full price for.
- No throttling: API rate limits become a real problem at 10K/day. Dedicated hardware has no artificial caps.
Situations Favouring APIs
- Seasonal demand: If 10K/day only happens during holiday campaigns, pay-per-image may be cheaper than year-round dedicated hardware.
- Multi-region delivery: If you need images generated close to users globally, distributed API endpoints beat a single server location.
- Model-specific requirements: DALL-E 3’s text rendering or Midjourney’s artistic style are not replicable on open-source models yet.
The Right GPU for 10K/Day
The RTX 5090 at £179/month provides the raw compute and 32 GB VRAM needed for sustained high-volume generation. Its performance headroom means you can push to 15K images/day without upgrading. For the highest throughput, pair FLUX.1-schnell with the RTX 5090’s memory bandwidth — you will achieve faster per-image times than any API provider delivers.

10,000 images per day, £179/month. That is 88% cheaper than Stability AI with faster generation and zero rate limits.
