Batch Image Generation API:One Key, Many Models

Use one GPTProto API key to run image jobs with GPT Image 2, Nano Banana, Seedream and other supported models. Compare outputs and costs on a sample set, then scale the model that fits your catalog or creative brief.

// Batch output

Different images needdifferent models.

A catalog image, a game asset and a campaign visual may need different models. Test GPT Image 2, Nano Banana and Seedream with the same GPTProto key and shared balance. Keep your asset IDs and output review in one production workflow.

// SAME PROMPT, DIFFERENT RESULTS

One prompt. Sixteen models.See what each gets right.

Give each model the same brief and inspect the result before you commit a full image run. Compare the details it follows, the time this sample took and the cost of this request.

PromptAlmost every wine photo in training data shows a glass a third full, so models default to it. Filling the glass to the rim tests whether a model follows the prompt or the prior.

A wine glass filled to the brim with white wine, the surface level with the rim of the glass, standing upright on a plain wooden table. Straight-on eye-level shot, glass upright and not tilted, no other objects in the frame.

// PRODUCTION WORKFLOWS

When a job fails, know
which image is missing.

One GPTProto key lets you work across supported image models. A 5,000-image run still needs to be traceable item by item: keep task IDs, check statuses and review failed or uncertain submissions before rerunning them.

01

Pengalihan Otomatis

Image models run on redundant upstream channels. If one drops mid-batch, traffic shifts to a backup automatically — the run finishes instead of erroring out.

02

Saluran Upstream Redundan

Model utama disediakan melalui saluran upstream redundan, sehingga gangguan pada satu penyedia tidak akan melumpuhkan aplikasi Anda.

Jelajahi model
03

Pemantauan 24/7

Traffic is monitored continuously and shifted automatically — problems get routed around before your pipeline ever notices.

#Routing

For a team already juggling DeepSeek, Kimi, Qwen, or other providers, a shared routing layer can be reasonable if it removes duplicated work and the fallback behavior is tested. GPTProto is one implementation of this approach.

#Cost

I've been testing GPTProto recently, and it's honestly made my creative workflow much simpler. Instead of paying for multiple subscriptions, I can access several leading AI models from one place.

#Integration

What worked for me was pointing the cloud connections at GPTProto so the frontend only sees one endpoint and I just change the model name to swap. I am not rebuilding a connection from scratch every time.

// FAQ

Questions beforethe first batch

The practical details behind image jobs, model choices and costs.

01Does GPTProto offer a single Batch API for image jobs?+

The documented GPT Image 2 bulk workflow submits image requests through its model endpoint, stores a returned task ID for each request and checks the corresponding result. Do not assume that an OpenAI-style JSONL Batch endpoint is available on GPTProto. See the step-by-step guide for the current workflow.

02Can I generate images for different products in the same run?+

Yes. Keep one record per product or asset in your own queue, generate the model-specific request for each record and save the task ID with its SKU. Multiple variations of a single prompt and requests for many different products are two different workflows; choose the one your job requires.

03Can I use the same GPTProto API key for GPT Image 2, Nano Banana and Seedream?+

Yes, for supported models in your account: one GPTProto key and shared balance let you try different image models. Each model can still have its own endpoint, request fields, output format and billing unit. Check the model documentation before you change a production worker.

04How do I keep a long run from losing track of results?+

Save the asset ID, prompt version, model, settings and returned task ID after each accepted request. Query the task status and store the finished file in your own asset storage. On restart, check known task IDs before creating new jobs.

05What should I do if a request times out or hits a rate limit?+

Follow any rate-limit guidance and reduce concurrent submissions when you receive a 429. A connection timeout on a submission can leave the outcome uncertain; check your task history before resubmitting, because the first request may already have been accepted and billed. Review content or parameter errors rather than retrying them unchanged.

06Can a reference image keep every output identical?+

Reference and edit inputs depend on the model and task. They can help guide a look or preserve details, but they do not guarantee identical results across models or across every item. Test representative items and review product fidelity before a full run.

07How is the cost per image calculated?+

It depends on the model. Some models charge per request or output, while GPT Image 2 is listed with input and output token rates on its model page. Choose your actual size and quality, measure a sample and count retries or rejected results when forecasting production cost.

08Can I move an existing OpenAI image workflow over unchanged?+

Some supported OpenAI-compatible routes may need only configuration changes, but do not assume that applies to every model. For example, the documented Midjourney route has a different path. Confirm request fields, status handling and output formats with a sample before migration.

09Are top-up bonus credits included in the savings calculator?+

The model-rate comparison and any bonus-credit offer should appear separately. Check the current credit and eligibility terms at checkout; the estimate on this page must show which of the two it includes.

10Can I get invoices for my company?+

Contact the GPTProto team or check the account billing page for the current invoice request process and supported invoice details.
