Nano Banana 3.1 Flash API: fast AI image generation up to 4K
Nano Banana 3.1 Flash is Google's fast, high-volume image model, generating and editing images from text prompts with reference images, aspect ratios, and resolutions up to 4K. It is built for speed, making it well suited to producing large batches of images quickly.

What is Nano Banana 3.1 Flash?
Nano Banana 3.1 Flash is Google's fast image-generation model in the Nano Banana 3 family. It creates images from text prompts and can also edit existing images using reference images, text instructions, chosen aspect ratios, and resolutions up to 4K. Built for high-volume, low-latency generation, it is designed to produce many images quickly rather than to maximize per-image render time. It is well suited to product imagery, concept art, marketing visuals, and creative experimentation where speed and resolution both matter. Pricing is token-based: $1.00/1M input, $120.00/1M output (~$0.10 est.) per generation.
Build with Nano Banana 3.1 Flash via YepAPI
Submit image jobs to YepAPI's /v1/media/queue endpoint with your API key, providing a text prompt and optional reference images, aspect ratio, and resolution up to 4K. The queue model lets you fire off generations and retrieve results as they complete, which suits batch and high-volume image workloads. One key also unlocks text models and YepAPI's SEO, SERP, and scraping APIs, so you can, for example, scrape product data, write copy, and generate matching imagery through a single integration.
Nano Banana 3.1 Flash API pricing — token-based, ~$0.10 per image
Nano Banana 3.1 Flash uses token-based pricing: $1.00/1M input, $120.00/1M output (~$0.10 est.) per generated image. Rather than a fixed per-image fee, cost reflects the tokens consumed by the prompt and the generated output, with a typical image landing around ten cents. That makes high-volume generation predictable and affordable, especially when you produce many variations or edits in a batch.

The model is built for generating and editing images at scale: product shots in multiple aspect ratios, marketing creative variations, concept art, and edited versions of existing assets using reference images. Its speed lets you produce large batches quickly, and 4K output supports production-quality results. Paired with YepAPI's scraping and SEO tools on the same key, it fits content pipelines that gather data and produce matching visuals together.
