01overview
What is Nano Banana 2?
Nano Banana 2 is Google's Gemini 3.1 Flash Image model — fast text-to-image generation plus instruction-based editing with strong character consistency. On Prospolabs you call it the same way for both: a generate mode for text-to-image and an edit mode that accepts up to 14 reference images to compose or transform a single output, no masks required.
Prospolabs runs Nano Banana 2 pay-per-generation in plain USD — no tokens, no subscription. You pick a resolution (1K, 2K, or 4K), pay only for images that succeed, and top up from $5. The price is identical whether you generate in the Prospolabs UI or hit the API, and failed runs are refunded automatically.
Pricing on Prospolabs starts at $0.048/image at 1K against a retail rate of $0.080 — roughly 40% off — so a batch of 100 images at 1K costs $4.80. That makes Prospolabs one of the cheapest ways to put Nano Banana 2 into production without committing to seats or monthly plans.
The cheapest way to run Nano Banana 2 in production
Prospolabs prices Nano Banana 2 at $0.048/image at 1K versus $0.080 retail, $0.072 at 2K versus $0.120, and $0.096 at 4K versus $0.160 — about 40% off across every resolution. There are no tokens, no seats, and no monthly minimum: top up from $5, pay per image in USD, and get failed runs refunded automatically. A batch of 100 images at 1K runs $4.80 on Prospolabs.
02capabilities
What Nano Banana 2 can do
Text-to-image (generate mode)
Send a prompt to generate mode and Nano Banana 2 produces a finished image. It parses conversational instructions holistically rather than matching tags, so natural-language prompts work well for product shots, posters, and marketing visuals.
Image editing with up to 14 references (edit mode)
Edit mode accepts up to 14 reference images and a text instruction to compose or transform them into one output — swap backgrounds, change colors, add or remove objects, or composite multiple subjects. No masks or manual selection needed.
Resolution control: 1K, 2K, 4K
Choose 1K, 2K, or 4K per request. On Prospolabs that maps directly to price — $0.048, $0.072, and $0.096 per image — so you only pay for the fidelity a given job actually needs.
Aspect ratio and format controls
Set aspect_ratio across many presets (square, portrait, widescreen, ultra-wide and more), output_format as png, jpeg, or webp, and safety_tolerance to tune filtering. Pick the framing up front so you avoid re-crops downstream.
Character consistency
Nano Banana 2 holds character resemblance across generations, which makes it practical for sets — a recurring brand mascot, a product across multiple scenes, or a cast of figures that needs to look the same frame to frame.
03use cases
What people build with Nano Banana 2
Batch product and ecommerce imagery
Generate catalog and hero shots at scale. At 1K on Prospolabs that's $0.048/image, so 100 product images cost $4.80 — and you only pay for the ones that come back.
Reference-driven edits and compositing
Feed up to 14 reference images into edit mode to merge subjects, restyle a scene, or place a product into a new setting from a single text instruction — no masking pipeline to maintain.
Social and ad creative variations
Use aspect_ratio presets to produce square, vertical, and widescreen cuts of the same concept, then push resolution to 2K or 4K only for the placements that need print-grade clarity.
Consistent character sets
Keep a mascot or recurring subject looking the same across a campaign, storyboard, or app, leaning on Nano Banana 2's character consistency instead of re-prompting from scratch.
