Nano Banana vs Midjourney v7: A Spec & Pricing Comparison

Google DeepMind's Nano Banana Pro and Midjourney v7 sit at the top of two very different image-generation stacks. Nano Banana Pro is an API-first model from a hyperscaler, priced per image, built for compositional control and 4K output. Midjourney v7 is subscription-only, lives behind Discord and a web UI, and is built around an aesthetic flywheel of personalization, moodboards, and references.

This guide compares only what each maker has officially documented. Third-party numbers are flagged as such.

TL;DR

• Nano Banana Pro generates native 1K, 2K, or 4K output, maintains the resemblance of up to five characters, blends up to fourteen reference images, and is sold per image (~$0.134 at 1K/2K, ~$0.24 at 4K) on the official Gemini API.
• Midjourney v7 runs subscription-only ($10–$120/month), tops out natively at 1024×1024 with a 2× upscaler to 2048×2048, and ships Draft Mode (10× faster, half the GPU cost) plus Omni Reference for character/object consistency.
• There is no official Midjourney public API. Programmatic access is enterprise-only.
• Commercial license differs sharply: Midjourney requires a Pro or Mega plan once your company crosses $1M in annual revenue; Nano Banana Pro outputs follow standard Google Cloud terms.

Maker and release timeline

Nano Banana Pro is the consumer name for Google DeepMind's gemini-3-pro-image-preview. The Google blog announcement dates the release to November 20, 2025. It is built on Gemini 3 Pro and is the higher-end sibling of the older Nano Banana model.

Midjourney v7 went into alpha on April 4, 2025 and became the platform's default model on June 17, 2025. v7 mandates personalization: users must rate ~200 images to unlock the profile.

Resolution: native 4K vs 2K upscale

Google DeepMind states Nano Banana Pro can "generate crisp visuals at 1k, 2k or 4k resolution" (source). At 4K, that is 4096×4096 pixels in a single pass, no upscaler in the loop.

Midjourney v7 starts at 1024×1024 for the default 1:1 aspect ratio. According to documentation aggregators referencing Midjourney's Image Size & Resolution page, the Creative and Subtle upscalers cap at a 2× enlargement, giving a 2048×2048 maximum output. The total pixel ceiling is 3 megapixels regardless of aspect ratio.

For deliverables that need native 4K (print, billboards, OLED), Nano Banana Pro is the only one of the two that gets there in a single render. Below 2K, the difference is academic.

Character consistency and reference images

Google DeepMind's official claim is precise: Nano Banana Pro can "maintain the consistency and resemblance of up to five characters and the fidelity of up to fourteen objects in a single workflow" (source). The number on the page is the spec. If your campaign brief says "the same five people across 30 shots," that is what the model is built around.

Midjourney v7's analogue is Omni Reference (--oref), introduced after the v7 alpha launch. The V7 default model announcement cites Omni Reference as one of the reasons v7 was promoted to default. Midjourney does not publish a numeric figure for how many subjects Omni Reference can lock simultaneously. v7 also ships updated Style Reference (--sref) and moodboard algorithms that the V7 Alpha post describes as more precise than the V6 equivalents.

Claimed vs confirmed: Google's "5 characters / 14 objects" is a published spec. Midjourney's Omni Reference is a documented feature, but the upper bound on simultaneous consistent subjects is not specified.

Style strength and aesthetic control

This is where Midjourney's product DNA shows up. The V7 Alpha announcement describes v7 as "much smarter with text prompts" with improved textures, hand accuracy, and body coherence. The mandatory personalization profile shapes every output to your visual taste. Midjourney also ships the experimental --exp parameter (range 0-100) that, per the V7 update post, makes images "more detailed, possibly more dynamic, creative, and more 'tone mapped'."

Nano Banana Pro does not publish a comparable personalization mechanism; its style controls are prompt and reference-image driven. For aesthetic consistency across a body of work, Midjourney's personalization + sref + moodboard stack is the system explicitly designed for that workflow.

Claimed vs confirmed: Midjourney's claims are official; independent benchmarks for style consistency at scale are not published by either maker.

Text rendering inside images

Google calls Nano Banana Pro "the best model for creating images with correctly rendered and legible text" with multilingual support (source). The DeepMind product page cites the lowest single-line text-rendering error rates in their internal benchmark across multiple languages.

Midjourney v7 improved text rendering over v6 but does not market in-image text as a flagship capability. For dense text (poster typography, infographic labels, multilingual signage), Nano Banana Pro has the explicit positioning.

Pricing: per-image vs subscription

This is the largest structural difference between the two stacks.

Nano Banana Pro (per image)

The Google blog developer announcement confirms paid-preview availability via Google AI Studio and Vertex AI but does not publish a numeric per-image rate on the announcement page. Third-party aggregators consolidating the official Gemini API pricing report:

• ~$0.134 per 1K-2K image
• ~$0.24 per 4K image
• 50% discount via the Batch API (~$0.067 / $0.12)

Source for the third-party numbers: PiAPI's Nano Banana Pro pricing page and other API resellers. Always confirm the live rate in your Google Cloud console; published numbers from non-Google sources can lag.

Midjourney v7 (subscription)

Per Midjourney's Comparing Plans documentation (figures consolidated from multiple independent reviews of that page):

Annual billing is a 20% discount. Relax mode (slower queue, no GPU-hour cost) is unlimited from Standard up. Stealth mode, which keeps your generations private, is Pro and Mega only.

Cost comparison at common usage

For ~500 images/month at 1K-2K: Nano Banana Pro runs $67 (500 × $0.134); Midjourney Standard is $30 flat. For ~50 4K renders/month: Nano Banana Pro is $12; Midjourney is not natively 4K and would need an external upscaler on top of $30/month Standard. Subscription wins for constant use; per-image wins for bursty workloads or when you specifically need 4K.

Commercial license

Midjourney publishes the most explicit commercial-use rules in the category. Per the official commercial use documentation (referenced via documentation aggregators because the page returns 403 to direct fetch), paid subscribers own the images they generate and may use them commercially. Free trial users only receive a Creative Commons BY-NC 4.0 license: no commercial use, attribution required. Companies above $1 million USD in annual gross revenue must subscribe to the Pro or Mega plan to use Midjourney commercially.

Nano Banana Pro outputs are governed by standard Google Cloud / Vertex AI / Gemini API terms. There is no revenue gate inside the consumer Gemini app or Google AI Studio paid tiers. Enterprise users on Vertex AI can layer indemnification through their existing Google Cloud agreement.

For a company crossing the $1M revenue line, the Midjourney plan upgrade is mandatory; for Nano Banana Pro it is not.

Availability and API

Nano Banana Pro is available in the Gemini app (free + AI Plus / Pro / Ultra tiers, per the Google blog), Google AI Studio, the Gemini API (paid preview), and Vertex AI for enterprise. The Gemini app's free tier has a small daily quota before reverting to the older Nano Banana model.

Midjourney v7 runs on Discord and the Midjourney web app. There is no official public API. Reports indicate enterprise API discussions exist but no release date. Third-party API services operate outside Midjourney's official terms. If your workflow requires programmatic generation behind an API key, Midjourney is structurally not the answer in 2026.

Who should pick which

Choose both if you can: draft and ideate in Midjourney v7 Draft Mode (10× faster, half-cost per the V7 Alpha post), then re-render the keepers in Nano Banana Pro at 4K when pixel density and character consistency on-brief matter. The two models work as complements at different points in the same pipeline.

Frequently asked questions

What is the difference between Nano Banana and Midjourney v7?

Nano Banana Pro (gemini-3-pro-image-preview) is Google DeepMind's API-first model, released November 20, 2025, priced per image (~$0.134 at 1K-2K, ~$0.24 at 4K). Midjourney v7, default since June 17, 2025, is subscription-only ($10-$120/month) and has no official public API. Nano Banana Pro generates native 4K; Midjourney v7 maxes at 2048×2048 after upscaling.

Does Midjourney v7 have an API?

No official public API exists as of 2026. An enterprise API is reportedly under discussion with no announced release date. Third-party services that automate Midjourney via Discord operate outside Midjourney's terms. If API access is a requirement, Nano Banana Pro is API-native via the Gemini API and Vertex AI.

Is Nano Banana Pro really 4K?

Yes. Google DeepMind states the model can "generate crisp visuals at 1k, 2k or 4k resolution" (source), up to 4096×4096 in a single render. Midjourney v7 starts at 1024×1024 and the Creative/Subtle upscalers cap at 2048×2048.

Which one is cheaper?

It depends on volume. Midjourney's $10/month Basic plan is the cheapest single-platform entry. For per-image use, Nano Banana Pro at ~$0.134 wins on small batches. For 500+ images/month, Midjourney's $30/month Standard plan is usually cheaper. For 4K specifically, Nano Banana Pro's $0.24 per image is the only native option of the two.

Can I use both for commercial work?

Yes, with conditions. Midjourney requires a paid plan for commercial use, and companies above $1 million in annual revenue must subscribe to the Pro or Mega plan. Nano Banana Pro follows standard Google Cloud / Vertex AI terms without a revenue gate. Both let you keep ownership of paid generations.

Where can I try each?

Nano Banana Pro is available in the Gemini app (free tier with a daily quota) and Google AI Studio. Midjourney v7 requires a paid subscription starting at $10/month, with no free trial as of 2026. The studio at gptimg.co wraps the Nano Banana Pro API so you can test it without setting up Google Cloud.
