Best Image To Image APIs in 2026

Restyling, upscaling, relighting, variation: image to image spans a wide set of transforms, and the strongest model shifts with the job. Rather than commit to one, this guide maps the entire image to image API selection on Pixazo, updated against the live catalog, so you can compare all 25 models from a single integration.

Frequently asked questions

What is a reference-to-image API?

A reference-to-image API is an image-to-image workflow where you supply one or more reference images to guide the output — keeping a character, style, or product consistent across new generations. The models below (GPT Image 2, Nano Banana 2, Seedream and others) all support reference-driven generation through the Pixazo API.

Which image to image API is best in 2026?

It depends on your use case — GPT Image 2, Nano Banana 2 Lite and Seedream 5.0 Pro are among the strongest right now. Because every model here runs on one Pixazo endpoint, the fastest way to decide is to test them on your own inputs.

Can I switch between these models without changing my code?

Yes. Pixazo exposes every image to image model through a single API — you change one model parameter, not your integration, and billing stays unified.

Are new models added automatically?

This list is refreshed from Pixazo’s live image to image catalog, so newly launched models appear on the same endpoint as they go live.

How does pricing work?

Pay-as-you-go through one key, with no per-provider contracts. See the Image To Image API page for current rates.

Is there a free image to image API to start with?

Yes. Create a free key from the Pixazo API console and call any model on this list right away, then move to pay-as-you-go as your volume grows.

Do I need a separate API key for each model?

No. One Pixazo key works across every image to image model here, so you can benchmark and switch models without managing separate credentials or contracts.

Which model should I start with?

GPT Image 2, Nano Banana 2 Lite, Seedream 5.0 Pro are strong defaults today. Because they share one endpoint, the fastest way to choose is to run the same input through each and compare the results.

Can I use the outputs commercially?

Commercial rights depend on the specific model you call. Check each model page for its licensing terms before shipping to production.

How do I get started with the image to image API?

Grab a key from the API console, pick a model from the list above, and send your first request to the unified endpoint.
