}Models + pricing from ViralMint's open-source pipeline, updated 2026-07.
Nano Banana (~6¢) for everyday quality, budget FLUX.2 Klein (~3¢) for cheap iteration, Gemini 3.1 Flash, GPT Image 2 and Nano Banana Pro when the shot deserves it — or hit Auto and ViralMint picks the best model for your prompt, always cost-capped. One tool, one balance, no per-model subscriptions.
Midjourney starts at $10/month, ChatGPT Plus is $20/month, Canva Pro is ~$15/month — all subscriptions you pay whether you generate or not. ViralMint charges per image (~$0.06) from a prepaid balance. A creator generating 30 thumbnails and b-roll images a month pays under $2. No watermark, commercial use permitted.
The built-in prompt libraries — Nano Banana, GPT Image 2, Seedream, Grok Imagine — ship hundreds of curated prompts with preview images, so you start from a look you can see rather than a blank box. Every prompt is one click to load into the generator, and any past generation can be remixed with a tweaked prompt from your history.
Download the free ViralMint desktop app (macOS / Windows / Linux) and open the AI Image studio from the Tools page.
Type your own prompt, or open the prompt drawer and pick from 600+ curated prompts with preview images (Nano Banana, GPT Image 2, Seedream and Grok Imagine packs). One click loads the prompt into the box.
Nano Banana (~6¢) for the best quality, or the budget FLUX.2 Klein (~3¢) for cheap iteration. Square, portrait or landscape. Optionally attach up to 3 reference images for multi-reference composition.
Images render in ~3–10 seconds at about 6 cents each. Download the PNG, remix it with a tweaked prompt, or send it straight into a video as AI b-roll or a thumbnail.

Two, behind one picker: Nano Banana (Google's Gemini 2.5 Flash Image) at ~6¢ and the budget FLUX.2 Klein at ~3¢. Pick per image — Nano Banana for the best quality, FLUX.2 Klein for cheap iteration.
Yes. The model licenses permit commercial use of generated output, and ViralMint adds no restriction — use them in YouTube thumbnails, TikTok b-roll, ads, products, anywhere. No attribution required.
Yes — attach up to 3 reference images for multi-reference composition (take the palette of one, the layout of another). You can also remix any past generation from your history with a tweaked prompt instead of starting over.
ViralMint curates free prompt libraries for Nano Banana, GPT Image 2, Seedream and Grok Imagine — 600+ prompts, each with a preview image so you can see the look before spending a cent. They're also published free at viralmint.net/tools/nano-banana-prompts/ and the other library pages.
The app is a free download and there's no subscription — you pay only for what you generate (~6¢/image), with a small daily free allowance for registered accounts. That's a different trade than 'free' web generators, which typically watermark output, cap daily renders, or train on your images.
The AI Image Generator ships inside the free ViralMint desktop app — no subscription, no watermark, no per-minute cap. Download once, use on as many videos as you want.
