What image generation endpoint should I use for a production SaaS?

For a production SaaS, the safest default is to use the Images API endpoint rather than a chat/completions endpoint.
Recommended choice
Use the dedicated image generation endpoint, typically:
POST /v1/images/generations
This is the purpose-built endpoint for generating images and is the cleanest fit for a product workflow.
Why this is the right choice for SaaS
- Purpose-built: optimized for image generation use cases.
- Stable integration: easier to maintain than routing image requests through general text/chat endpoints.
- Better product fit: supports a clean separation between text, image generation, and other modalities.
- Operational clarity: easier to log, retry, rate-limit, and monitor in production.
When you might choose something else
If your SaaS needs:
- edits/inpainting → use the image edits endpoint
- variations → use the variations endpoint
- generation inside a broader multimodal workflow → keep using the dedicated images endpoint for the actual image step, even if the rest of the flow uses chat/responses
Production advice
For a production SaaS, also make sure you:
- generate images server-side
- keep your API key off the client
- add rate limiting and retries
- store request/response metadata for auditing
- check the model’s current availability, pricing, and policy requirements before shipping
If you want, I can also recommend the best model, response format, and a production-ready request pattern for your SaaS.
