Nano Banana Pro: Pricing, Features & How It Compares to Midjourney and DALL-E 3
Nano Banana Pro is Google's nickname for Gemini 3 Pro Image, a native 4K image-generation model built into Gemini. It's free for casual use through the Gemini app; the full Pro feature set (multi-image fusion, pose control, higher limits) requires Google AI Pro at $19.99/month. API access is billed separately at roughly $0.134 per 1K/2K image and $0.24 per 4K image -- there's no free API tier.
Nano Banana Pro is Google's native-4K image model built into Gemini. Here's what it actually does, what it costs (free tier, Google AI Pro, and API pricing), and how it stacks up against Midjourney and DALL-E 3.
Nano Banana Pro: Pricing, Features & How It Compares to Midjourney and DALL-E 3
Nano Banana Pro is the nickname that stuck for Gemini 3 Pro Image, Google DeepMind's image-generation model. The name comes from an internal Google testing codename used on LMArena before the model's identity was public, and it's now the common way people refer to it even in official-sounding contexts.
What Is Nano Banana Pro?
Nano Banana Pro is Google's high-quality image-generation model, built into the Gemini app and available via API as gemini-3-pro-image-preview. It accepts detailed text instructions, can use reference images, and supports iterative refinement across multiple turns -- you can keep adjusting a single image conversationally instead of re-prompting from scratch. Built-in reasoning helps it organize complex scenes, place text accurately inside images, and keep object relationships and composition consistent.
Key Features
- Native 4K resolution (3840×2160) -- generated directly, not upscaled after the fact
- Accurate in-image text, a longstanding weak point for most image models
- Multi-image fusion and pose control on the Pro tier
- Multi-turn refinement -- adjust lighting, composition, or specific elements through follow-up prompts
- SynthID watermarking applied automatically to generated images
Pricing: Free vs Google AI Pro vs API
| Tier | Price | What You Get |
|---|---|---|
| Free (Gemini app) | $0 | Basic generation, standard resolution, limited daily usage |
| Google AI Pro | $19.99/month | Full Pro capabilities: 4K output, multi-image fusion, pose control, higher limits |
| API (per image) | ~$0.134 (1K/2K) / ~$0.24 (4K) | Pay-per-image access for developers, no free tier |
There's no free tier on the API specifically -- the free option only exists through the consumer Gemini app. Third-party API resellers (FAL.AI, Kie.ai, and similar platforms) offer their own pricing on top of the same underlying model, sometimes slightly cheaper per image.
Nano Banana Pro vs Midjourney vs DALL-E 3
| Nano Banana Pro | Midjourney | DALL-E 3 | |
|---|---|---|---|
| Free tier | ✓ Yes (Gemini app, limited) | ✗ No | ✗ No |
| Starting price | $19.99/mo (full features) | $10/mo (Basic, 200 images) | Retired -- no longer available |
| Max resolution | 4K native | High-res, upscaled | 1024-1792px |
| Interface | Gemini chat, natural language | Discord + web app | Was ChatGPT Plus / API |
| Strongest at | Photorealism, in-image text, 4K detail | Artistic/stylized imagery | Ease of use (while it lasted) |
DALL-E 3 was retired from OpenAI's API in May 2026, so it's included here for context rather than as a live option -- see our DALL-E 3 breakdown for what replaced it. Between the two tools still standing, Midjourney remains the stronger pick for stylized, artistic output, while Nano Banana Pro leads on photorealism and native 4K resolution -- it won the photorealism category in a majority of head-to-head blind tests circulating since launch.
How to Use Nano Banana Pro
Through the Gemini app, generation is conversational: describe the image in plain language, and refine it with follow-up messages rather than rewriting the whole prompt. For best results, be specific about composition, lighting, and any text that needs to appear in the image -- accurate in-image text is one of its clearest advantages over older models. Developers building it into an app use the gemini-3-pro-image-preview model through the Gemini API, billed per image based on output resolution.
Who It's For (and Who It Isn't)
Nano Banana Pro fits well for anyone who needs photorealistic images with accurate text -- product mockups, marketing visuals, or scenes with signage and labels. It's also a reasonable default for casual use, since the free Gemini tier is enough to try it without commitment. It's a weaker fit if stylized or painterly output is the goal -- that's still Midjourney's strength -- and the lack of a free API tier makes it less appealing for developers testing at scale compared to cheaper per-image alternatives.
Frequently Asked Questions
Is Nano Banana Pro free to use?
Yes, through the Gemini app's free tier, though with limited daily generations and standard (not 4K) resolution. Full Pro features require a Google AI Pro subscription at $19.99/month, and there's no free tier for API access.
What's the difference between Nano Banana and Nano Banana Pro?
Nano Banana was the original model (Gemini 2.5 Flash Image); Nano Banana Pro (Gemini 3 Pro Image) is the higher-quality successor with native 4K resolution, better text accuracy, and multi-image fusion. There are now several versions floating around under similar names, so it's worth confirming which one a given tool or API actually uses.
Does Nano Banana Pro watermark its images?
Yes, all generated images carry an invisible SynthID watermark applied automatically, which is Google's standard practice across its generative image and video models.
Is Nano Banana Pro better than Midjourney?
It depends on the goal. Nano Banana Pro generally wins on photorealism, in-image text accuracy, and native 4K output. Midjourney still leads for stylized, artistic, or painterly imagery where creative interpretation matters more than technical accuracy.
Can I use Nano Banana Pro through the API?
Yes, as gemini-3-pro-image-preview through the Gemini API, billed per image at roughly $0.134 for 1K/2K resolution and $0.24 for 4K -- there's no API free tier, unlike the consumer Gemini app.
