Before you queue
A few practical details.
Why does Gemini batch generation cost less?
These workflows use Gemini Batch API for queued generation. Their credit prices are lower than the matching interactive workflows, with longer completion times. Check the credit estimate before launching for the total with your selected model and settings.
Which models support Gemini batch generation?
Nano Banana 2 Lite, Nano Banana 2 and Nano Banana Pro have dedicated batch workflows: Gemini 3.1 Flash-Lite Image Batch, Gemini 3.1 Flash Image Batch and Gemini 3 Pro Image Batch.
What image resolution does Gemini batch support?
The current Gemini batch workflows generate 1K images. Choose from the aspect ratios supported by the model. For other image sizes, check the options in its interactive workflow.
How long does a Gemini batch take?
Gemini batches are queued and take longer than interactive generation. Completion time varies with the provider queue and the work submitted. You can leave the page and return to check the batch. Choose interactive generation to test and adjust with less waiting.
What are the current batch limits?
Gemini batch supports up to 100 prompts per workflow, up to 10 workflows, and up to 1,000 total generation items per batch. Each workflow can include up to 10 aspect ratios and 10 reference image sets, subject to the model’s supported options. Prompt, aspect-ratio and reference-set combinations count toward the total.
Can I vary prompts, aspect ratios and references?
Yes. Configure the prompts, supported aspect ratios, reference image sets and available settings for each model. References are optional for text-to-image generation. Review the image and credit totals in the app before you submit.
Which plans include Gemini batch generation?
Starter, Creator and Pro include all three Gemini batch models. The Lite plan excludes Gemini batch generation, including Nano Banana 2 Lite Batch. You need enough credits to cover the batch you submit.
How is this different from standard batch generation?
Standard batch groups generation requests across supported image models and allows up to 10 prompts per workflow. Gemini batch uses dedicated queued Nano Banana workflows, offers lower-cost 1K generation and allows up to 100 prompts per workflow. Choose based on the models, cost and timing your work needs.
