Nano Banana Pro

Overview

Nano Banana Pro is Google's advanced AI-powered image generation and editing model built on Gemini 3 Pro, offering studio-quality output with professional-grade creative control. The model supports resolutions up to 4096px (4K) and features significantly improved text rendering capabilities. Optional Grounding with Google Search can be enabled via the API for scenarios requiring up-to-date references. Available through the Gemini app for consumers and via API (Google AI Studio, Vertex AI) for developers, Nano Banana Pro is designed for professional content creators, designers, and development teams who need precise control over image generation, accurate text integration, and high-resolution outputs for commercial and creative projects.

Key Features

• Advanced Text Rendering — Delivers significantly improved text generation accuracy across multiple languages and styles, supporting multilingual text rendering with lower error rates. Ideal for creating posters, invitations, infographics, and diagrams.

• High-Resolution Output — Generates images up to 4096px (4K) with comprehensive aspect ratio support including 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, and 21:9, delivering professional-grade quality suitable for both print and digital media.

• Studio-Quality Control — Offers professional-level control over image generation and editing, including lighting adjustments, composition refinement, and style customization, enabling precise creative execution for demanding visual projects.

• Multi-Image Workflows — Accepts up to 14 input images per request, enabling composition consistency, character persistence, and brand identity maintenance across generated visuals.

• Optional Search Grounding — Developers can enable Grounding with Google Search via the API for scenarios requiring up-to-date references and contextual information.

• Flexible Developer Access — Available through Google AI Studio, Gemini API, and Vertex AI, enabling programmatic image generation and enterprise integration. Compatible with Antigravity IDE for agentic workflows.

• Provenance & Transparency — All generated images include an invisible SynthID watermark for verification and provenance tracking. The Gemini app can help verify whether an image was created or edited by Google AI, with C2PA credentials expanding to more surfaces.

Pricing & Plans

Nano Banana Pro is available through two primary access methods with different pricing structures:

Via Gemini App (Consumer Access)

• Free Tier — Limited access to Nano Banana Pro features with daily generation caps. On some surfaces, capacity-based routing may switch to a lighter model when limits are reached; exact caps and routing behavior are not fully documented.

• Google AI Pro / Ultra — Subscription tiers offering higher generation limits, priority access, and integration with Gemini in Gmail, Docs, Vids, NotebookLM, and other Google services. Benefits, availability, and limits vary by region. Subscriptions can be canceled any time (effective at the end of the billing period).

Via API (Developer Access)

Pricing as reported by TechCrunch at launch:

• 1080p or 2K Image — $0.139 per image
• 4K Image — $0.24 per image

For comparison, the original Nano Banana model was reported at approximately $0.039 per 1024px image, making Nano Banana Pro roughly 3.5-6x more expensive depending on resolution.

Important: Check current billing rates in Google AI Studio or Google Cloud Console, as pricing may change. API usage is pay-per-use with no subscription commitment required.

Pros & Cons

Pros

• Significantly improved text rendering — Delivers substantially better text accuracy compared to previous models, supporting multilingual text generation with lower error rates, though small fonts and long paragraphs may still degrade.

• Professional-grade resolution support — 4K output capability (up to 4096px) with comprehensive aspect ratio options meets commercial printing and high-quality digital publishing requirements.

• Optional world knowledge access — Search Grounding can be enabled via API for scenarios requiring up-to-date contextual references, though outputs still require human verification.

• Flexible access models — Available through consumer app (Gemini) and developer platforms (AI Studio, Vertex AI, Gemini API), accommodating different user types and use cases.

• Studio-quality creative control — Professional-level control over lighting, composition, and style enables precise creative execution for demanding visual projects.

• Built-in provenance tracking — Invisible SynthID watermark in all generated images enables verification and responsible AI usage tracking.

Cons

• Higher cost — API pricing is approximately 3.5-6x more expensive than the original Nano Banana model (based on launch reports), which may impact high-volume use cases. Current pricing should be verified in billing consoles.

• Slower generation compared to Flash models — Latency is higher than Gemini 2.5 Flash Image, which prioritizes speed over quality and control.

• Known spatial and editing limitations — Issues include spatial localization confusion (left/right positioning), partial instruction-following in masked/doodle edits, and infrequent copying from input images, requiring manual review.

Best For

• Content creators and designers who produce 10+ images per week requiring accurate text integration and professional-quality output
• Marketing teams managing multiple brand accounts that need consistent high-resolution visual assets across campaigns
• Technical writers and educators creating infographics, diagrams, and educational materials with text-heavy visual content
• Developers building AI-powered creative tools or applications requiring programmatic image generation via API
• Professional photographers and visual artists seeking AI-assisted editing with precise control over lighting, composition, and atmosphere
