On February 26, 2026, Google DeepMind officially launched Nano Banana 2 — technically named Gemini 3.1 Flash Image (model ID: gemini-3.1-flash-image-) — and immediately made it the default image generation engine across the Gemini app, Google Search’s AI Mode, Google Lens, Google Ads, and the AI filmmaking tool Flow. Within hours of launch, independent benchmarks placed the model at #1 in Text-to-Image in the Artificial Analysis Image Arena, a blind human evaluation leaderboard — at roughly half the API price of its predecessor, Nano Banana Pro.
That combination — benchmark-leading quality paired with Flash-tier speed and pricing — is the central story of this model. It is not a minor iteration. It collapses a cost-and-performance gap that has kept high-quality AI image generation out of many production pipelines since Nano Banana Pro launched in November 2025. For marketers, developers, and creative teams, understanding what Nano Banana 2 actually does — and where it fits against Pro — matters now. This guide covers every confirmed detail. Source
What Is Nano Banana 2, Exactly?
Nano Banana 2 is Google DeepMind’s third-generation entry in the Nano Banana family of image generation models. The “Nano Banana” name covers Google’s native image generation capability within the Gemini ecosystem — the ability to create, edit, and iterate on images conversationally, with text, images, or both as inputs.
The model’s full technical designation is Gemini 3.1 Flash Image Preview, and it sits on top of the Gemini 3.1 Flash reasoning backbone. That architecture distinction matters: the original Nano Banana Pro runs on Gemini 3 Pro, Google’s highest-tier reasoning model. Nano Banana 2 runs on the Flash variant of that same generation — a version optimized for speed and throughput, not depth of deliberation.
In practical terms, Google describes the positioning as: Nano Banana Pro for high-fidelity tasks requiring maximum factual accuracy; Nano Banana 2 for rapid generation, precise instruction following, and integrated image-search grounding. The two models are complements, not direct replacements, though Nano Banana 2 will serve as the default across Google’s entire consumer and developer ecosystem going forward. Source
The Nano Banana Model Timeline: How We Got Here
Understanding Nano Banana 2 requires some context on the family’s short but rapid development arc.
August 2025 — Original Nano Banana (Gemini 2.5 Flash Image) The first Nano Banana launched as a viral sensation, particularly in markets like India. Built on Gemini 2.5 Flash, it prioritized speed and was designed for high-volume, low-latency image generation tasks. It lacked many of the reasoning-intensive features of later models. Source
November 2025 — Nano Banana Pro (Gemini 3 Pro Image) Google released Nano Banana Pro with substantially improved visual fidelity, accurate text rendering, complex multi-subject scene handling, and what Google called “studio-quality creative control.” It ran on Gemini 3 Pro and impressed developers with its reasoning capabilities — but was priced at $120 per million output tokens, roughly $0.134 per 2K image and $0.24 per 4K image. For high-volume applications, that cost structure was prohibitive. Source
February 26, 2026 — Nano Banana 2 (Gemini 3.1 Flash Image) Today’s release brings many of Nano Banana Pro’s key capabilities to the Flash architecture, at Flash-tier pricing. The result is a model that produces images faster than Pro, at approximately 50% lower cost per image, while matching or approaching Pro quality across most common use cases. Source
The Six Core Capabilities of Nano Banana 2
1. Advanced World Knowledge via Real-Time Web Search Grounding
Nano Banana 2 does not rely solely on its training data when generating images. It can draw on Gemini’s real-world knowledge base and real-time information from live web search to more accurately render specific subjects.
This means you can ask the model to depict a specific landmark — like Museum Clos Lucé — and it will search for visual references before generating, rather than hallucinating architectural details from training data. The same capability makes it viable for generating current event infographics, maps based on recent data, and brand assets tied to specific real-world subjects.
A distinct new capability in Nano Banana 2 that Nano Banana Pro does not currently have is Google Image Search Grounding — the model can search for images specifically (not just web text) and use those retrieved images as visual context for generation. This is particularly useful for reference-matched product photography or accurate depictions of real-world subjects. Source
2. Precision Text Rendering and Localization
Text inside AI-generated images has historically been one of the weakest points of the technology — garbled letters, nonsense strings, illegible fonts. Nano Banana 2 addresses this directly. The model generates accurate, legible text within images for marketing mockups, greeting cards, event posters, and infographics.
More significantly, it supports in-image text translation. You can prompt the model to take an image with English text and localize it — translating the embedded text into Spanish, Hindi, Arabic, or other languages — without altering the surrounding visual composition. For global marketing campaigns where localized creative assets need to be produced at scale, this capability alone changes the production math. Source
3. Subject Consistency Across Characters and Objects
One of the hardest problems in AI image generation is keeping characters or branded objects looking the same across multiple generated images. Nano Banana 2 handles this directly, maintaining:
- Character resemblance for up to 5 characters in a single workflow (slightly fewer than Nano Banana Pro’s 5-character ceiling, though the Flash model supports more reference objects overall)
- Fidelity for up to 14 reference objects — meaning you can supply up to 14 distinct reference images of objects or characters and the model will incorporate them while preserving their visual identity
This capability enables storyboarding, product catalog generation, and brand asset workflows where a character, mascot, or product must look consistent across dozens or hundreds of images. As Nano Banana 2’s documentation notes, the allocation between characters and objects is split: up to 10 objects and up to 4 characters in the Flash variant, compared to up to 6 objects and 5 characters in Pro. Source
4. Precise Instruction Following for Complex Prompts
Nano Banana 2 improves on the original Nano Banana’s ability to interpret nuanced, multi-layered prompts. Google describes this as the model adhering “more strictly to your complex requests, capturing the specific nuances of your idea so the image you get is the image you asked for.”
In practice, this means prompt engineering matters less with Nano Banana 2 than with previous image models. Detailed instructions about lighting direction, color palette, compositional elements, emotional tone, and perspective are more likely to be honored in the output. This matters especially for teams generating large volumes of assets where iteration cost is significant. Source
5. Production-Ready Resolutions and Aspect Ratios
Nano Banana 2 supports image generation from 512px up to 4K resolution, with an expanded range of aspect ratios:
- Standard: 1:1, 4:3, 3:4, 2:3, 3:2, 16:9, 9:16
- Extended (new in Nano Banana 2): 1:4, 4:1, 1:8, 8:1, 21:9, 2:1
The 512px option is a new addition specific to Nano Banana 2 (not available in Pro), making it viable for lightweight applications where image file size matters. At the upper end, the model produces genuine 4K output, making it usable for print campaigns, large-format displays, and broadcast-quality creative assets.
This range covers the full spectrum of practical production formats: vertical social posts, widescreen video thumbnails, billboard compositions, and email marketing visuals. Source
6. Visual Fidelity at Flash Speed
The headline claim from Google is that Nano Banana 2 delivers “vibrant lighting, richer textures, and sharper details” at speeds associated with a Flash-tier model — potentially generating standard-resolution images in under two seconds. The model includes a Thinking mode with two configurable levels that let developers balance output quality against generation latency and cost depending on the use case.
Compared to the original Nano Banana, the visual quality jump is substantial. Compared to Nano Banana Pro, Google positions the gap as intentional: Pro remains the ceiling for maximum fidelity and creative reasoning, while Nano Banana 2 gets “close enough” for the majority of production workflows at meaningfully lower cost and higher throughput.

The pricing differential is worth pausing on. For a team generating 10,000 2K images per month through the API, Nano Banana 2 costs approximately $670 versus $1,340 for Nano Banana Pro — a saving of $670 per month, or $8,040 per year, before any volume discounts. At enterprise scale, those numbers compound significantly. [Sources: VentureBeat, WaveSpe
Where You Can Access Nano Banana 2 Right Now
Google’s rollout strategy for Nano Banana 2 is notably broad — it is launching simultaneously across virtually every Google consumer and developer surface.
Gemini App: Nano Banana 2 is now the default image generation model across all three Gemini tiers — Fast, Thinking, and Pro models. All users get it by default. Google AI Pro and Ultra subscribers retain access to Nano Banana Pro for specialized tasks by triggering image regeneration via the three-dot menu.
Google Search — AI Mode and Lens: Nano Banana 2 powers image generation in Google Search’s AI Mode and in Google Lens. The rollout covers 141 new countries and territories, with support for 8 additional languages, making this the widest geographic distribution of any Nano Banana model to date.
Google Ads: Nano Banana 2 is now live in Google Ads, powering the AI image generation that appears as creative suggestions when building campaigns. For performance marketers, this means Google’s ad platform will suggest assets generated by a meaningfully higher-quality model than was previously in place.
Flow (Google’s AI Filmmaking Tool): Nano Banana 2 is the new default image generation model in Flow, Google’s AI-powered video creation tool. Critically, it is available at zero credits for all Flow users — not just premium subscribers. This positions Nano Banana 2 as the visual backbone for AI-generated video workflows across the Google ecosystem.
AI Studio and Gemini API: Available now in preview at AI Studio using model ID gemini-3.1-flash-image-. Developers can access full documentation at ai.google.dev/gemini-api/
Google Cloud / Vertex AI: Available in preview through the Gemini API on Vertex AI, making it accessible for enterprise deployments within Google Cloud infrastructure with associated compliance and data governance controls.

Pricing Breakdown: What Nano Banana 2 Actually Costs
For consumer users in the Gemini app, Nano Banana 2 is included at no additional cost as the default model. The economics become relevant for developers and enterprises using the API.
Gemini API (Nano Banana 2 — Gemini 3.1 Flash Image Preview):
- Output tokens are priced at $60 per million (Flash tier)
- A 1K or 2K image outputs approximately 1,120 tokens, costing ~$0.067 per image
- A 4K image outputs approximately 2,000 tokens, costing ~$0.134 per 4K image
- Batch API rates further reduce costs by approximately 50%
Gemini API (Nano Banana Pro — Gemini 3 Pro Image Preview):
- Output tokens are priced at $120 per million (Pro tier)
- A 2K image costs approximately $0.134 per image
- A 4K image costs approximately $0.24 per image
- Thinking tokens add additional cost at ~$0.000025 per token
In Flow: Zero credits for all users. This is particularly significant for content teams building video workflows, as it removes the cost barrier for image generation in that context entirely.
The practical implication: Nano Banana 2 is priced for production deployment in a way that Nano Banana Pro was not. The original Pro model was well-suited for high-value, low-volume use cases. Nano Banana 2’s pricing makes it viable for e-commerce catalogs, automated social media pipelines, localized campaign variants, and any application generating hundreds of images daily.

Enterprise Adoption: What Real Organizations Are Saying
Within hours of launch, Google’s Cloud blog published testimonials from enterprise customers who received early access. These are worth examining carefully because they illustrate the practical use cases where Nano Banana 2 is already generating real business value.
Adobe Firefly integrated Nano Banana 2 into its creative suite. Steve Newcomb, VP of Product at Adobe Firefly, described the model as setting “a new standard for image quality and precision, giving creators greater control to generate and refine production-ready work in a seamless workflow.”
Figma and Weavy tested the model for iterative design workflows. Itay Schiff, Head of Product at Figma’s Weavy division, noted: “It stays responsive to our direction even after many rounds of edits, and the quality approaches Pro-level at faster speeds.” This is a specific validation of Nano Banana 2’s instruction-following capability in multi-turn editing scenarios — one of the most demanding use cases for any image generation model.
Notion integrated the model for in-document image generation. Software Engineer Jimmy Liu described a key behavioral change the model enables: “It’s fast enough that people stop treating image generation as a separate step and start using it the way they use text, as just another way to get an idea down.”
Whering, a fashion-tech company, used the model to transform user-uploaded clothing photos into studio-quality product imagery. CEO Bianca Rangecroft highlighted the model’s ability to “return structured, predictable outputs,” which enabled their team to build production pipelines “without sacrificing the complex image classification our users rely on.”
WPP and Unilever conducted enterprise-scale testing across client campaigns. WPP Chief Innovation Officer Elav Horwitz noted that “enhanced world knowledge anchored output in factual accuracy” and reported improvements in text fidelity that “reduc[ed] editing time from hours to seconds” for verticals requiring high-fidelity product representation. Source
These testimonials collectively point to a consistent theme: Nano Banana 2’s value is not just about raw image quality. It is about reliability, predictability, and the ability to integrate into professional workflows at speed — qualities that matter more than occasional peak performance in production contexts.
SynthID and C2PA Content Credentials: What Provenance Means in Practice
Every image generated by Nano Banana 2 is automatically marked with SynthID — Google DeepMind’s invisible digital watermark technology that allows AI-generated images to be identified. This watermark is embedded in the image data itself and persists even when images are cropped, filtered, or compressed.
Alongside SynthID, Nano Banana 2 images carry C2PA Content Credentials — metadata developed by the Coalition for Content Provenance and Authenticity, an industry body whose members include Google, Adobe, Microsoft, OpenAI, and Meta. C2PA metadata records not just whether AI was used to create an image, but contextual information about how it was created.
The practical difference: SynthID tells you an image is AI-generated. C2PA metadata tells you which model generated it, when, and under what parameters. Together, they provide a more complete provenance chain than either standard alone.
This matters increasingly for enterprise buyers, particularly in regulated industries. Media companies, financial institutions, and healthcare organizations operating under emerging AI transparency requirements need to demonstrate that AI-generated content is identifiable and auditable. The combination of SynthID plus C2PA in a single default model simplifies that compliance burden.
Google reports that since launching SynthID verification in the Gemini app in November 2025, the feature has been used over 20 million times across various languages. C2PA verification is coming to the Gemini app in the near term. [Sources: TechCrunch, 9to5Goog
The Competitive Picture: Where Nano Banana 2 Fits in the AI Image Landscape
Nano Banana 2 launches into a market with several well-established and rapidly improving competitors. Understanding the competitive positioning helps calibrate where and when to use the model.
Versus GPT Image 1.5 (OpenAI)
According to the Artificial Analysis Image Leaderboard at time of writing, the top Text-to-Image rankings show a closely contested space. GPT Image 1.5 from OpenAI, particularly in its “high” quality mode, and Nano Banana Pro have been the leading models in recent human evaluation benchmarks. Nano Banana 2 at launch is reported to take the #1 Text-to-Image position in the Artificial Analysis Image Arena at roughly half the price of comparable models.
A comparison published on Medium notes that GPT Image 1.5 is “noticeably faster” than Nano Banana Pro while Pro “prioritizes quality over speed” — a gap Nano Banana 2 is designed to close from Google’s side. For teams with existing OpenAI integrations, the choice often comes down to ecosystem fit and pricing structure rather than an absolute quality determination. Source
Versus FLUX.2 (Black Forest Labs)
FLUX.2 has developed a strong reputation for cinematic quality and structural clarity in complex compositional scenes. According to independent comparisons, FLUX.2 wins on cinematic feel while Nano Banana Pro wins on structural clarity and text rendering. Nano Banana 2’s text rendering advantage carries over from Pro, making it a stronger choice for any application requiring legible in-image text — a capability FLUX.2 has historically struggled with.
Versus Qwen-Image-2.0 (Alibaba)
This is the most significant competitive comparison to understand, because it explains part of the timing and positioning of Nano Banana 2’s launch. On February 10, 2026 — just sixteen days before Nano Banana 2’s release — Alibaba’s Qwen team released Qwen-Image-2.0, a unified image generation and editing model running on just 7 billion parameters.
Qwen-Image-2.0 generates natively at 2K resolution (2048×2048), supports prompts up to 1,000 tokens, and achieves results near or at the top of AI Arena’s blind human evaluation leaderboards. Its small parameter count means substantially lower inference costs when self-hosted — critical for organizations with data residency requirements.
Where Nano Banana 2 holds a clear advantage: ecosystem integration. Qwen-Image-2.0’s API access is currently limited to Alibaba Cloud. Nano Banana 2 is live across Google Search (141 countries), Gemini, Google Ads, Google Cloud, and Flow from day one. For teams already in the Google ecosystem, that breadth of distribution is difficult to replicate with a challenger model, regardless of raw quality scores.
The Qwen team previously released an Apache 2.0 license for their prior image model approximately one month after announcement, and the developer community widely expects the same for Qwen-Image-2.0. If open weights materialize, it will create a genuinely competitive option for self-hosted deployments at costs that no API provider can match. That is a longer-term consideration for enterprise AI strategy. Source
How to Use Nano Banana 2: A Developer Quick-Start
For developers integrating Nano Banana 2 via the Gemini API, the model is available today in preview. Here is the minimum viable call:
Python (Text-to-Image):
from google import genai
client = genai.Client()
response = client.models.generate_ content(
model="gemini-3.1-flash-image- preview",
contents=["Your image prompt here"]
)
REST (Direct API Call):
curl -s -X POST \
"https://generativelanguage. googleapis.com/v1beta/models/ gemini-3.1-flash-image- preview:generateContent" \
-H "x-goog-api-key: $GEMINI_API_KEY" \
-H "Content-Type: application/json" \
-d '{"contents": [{"parts": [{"text": "Your prompt here"}]}]}'
The model supports JavaScript, Go, Java, and REST in addition to Python. Full multi-turn editing, reference image workflows (up to 14 images), aspect ratio and resolution controls, and thinking mode settings are documented at ai.google.dev/gemini-api/
For non-developers, the model is accessible immediately in the Gemini app, in Google Search’s AI Mode when it appears, and in Google Lens via the Google app on iOS and Android.
Practical Implications for Marketers and Creative Teams
Nano Banana 2 changes the operational math for several specific marketing and creative workflows. Here is where the practical impact is sharpest:
Campaign Asset Localization at Scale The combination of accurate text rendering plus in-image translation means a single base creative brief can be adapted across multiple markets without separate design cycles. A product announcement banner created in English can be localized to Spanish, Hindi, French, or Arabic — complete with translated in-image text — in minutes. For global brands managing multi-market campaigns, this compresses timelines significantly.
Social Media Content Pipelines The extended aspect ratio support (including 9:16 for vertical video thumbnails and social stories, 16:9 for YouTube, and 1:1 for feed posts) means Nano Banana 2 can generate correctly formatted assets for every major social platform from a single prompt workflow. Combined with subject consistency across up to 5 characters, it can produce consistent branded character assets across campaign touchpoints.
E-Commerce Product Photography Whering’s use case — transforming user-uploaded product photos into studio-quality assets — illustrates a high-volume application where both quality and predictability matter. Nano Banana 2’s ability to accept up to 14 reference images and maintain object fidelity makes it viable for product catalog generation at scale, something that previously required either human photo studios or expensive AI workflows.
Google Ads Creative Testing With Nano Banana 2 now powering creative suggestions directly in Google Ads, performance marketers will see AI-generated image suggestions improving in quality. This tightens the loop between creative generation and campaign deployment: rather than exporting assets from a separate AI tool and importing them to Ads, the generation happens natively within the campaign-building workflow.
Infographic and Data Visualization Production The real-time web search grounding means Nano Banana 2 can generate infographics based on current data — not just static knowledge from its training set. A financial services firm producing weekly market summary graphics, or a media company illustrating a breaking news story, can prompt the model to ground its generation in up-to-date information rather than historical training data alone.
Developer-Built Consumer Applications For product and engineering teams, Nano Banana 2’s pricing makes it viable to embed in consumer-facing applications in ways that Pro-tier pricing did not permit. An app charging users $5/month cannot absorb $0.134-per-image API costs at any meaningful volume. At $0.067 per image, the economics of embedding image generation into applications begin to close. [Sources: Search Engine Land, Google Cloud Blog]
When You Should Still Use Nano Banana Pro
Nano Banana 2 does not make Nano Banana Pro obsolete. There are specific use cases where the Pro model’s additional reasoning depth and higher ceiling on text accuracy justify its higher price and slower generation speed.
Pro remains the stronger choice when:
- Text accuracy is critical at a character level — for packaging design, legal documents embedded in images, or medical infographics where a single misrendered character has real consequences
- Complex scene compositions with maximum fidelity — high-end print campaigns, billboard designs, or premium editorial imagery where “close enough” is not acceptable
- 5-character consistency requirements — Pro supports consistency across 5 characters versus Flash’s 4-character limit, which matters for narrative storyboards or ensemble cast promotions
- Maximum creative reasoning — cases where the model needs to “think through” unusual compositional challenges or highly specific artistic briefs that benefit from the deeper reasoning of the Pro backbone
- Archival or legally significant outputs — where the provenance metadata of maximum-fidelity generation is important for documentation purposes
Google AI Pro and Ultra subscribers retain access to Nano Banana Pro via the three-dot regeneration menu in the Gemini app. For API users, both models are available in preview simultaneously. Source
What Nano Banana 2 Signals About AI Image Generation’s Direction
The launch of Nano Banana 2 is not just a product update — it reflects a broader shift in how AI image generation is being positioned by Google. Several patterns are worth noting for teams thinking about their medium-term creative technology strategy.
Premium Features Are Moving to Default Tiers Nano Banana Pro was positioned as a premium product when it launched in November 2025. Three months later, most of its signature features — text rendering, subject consistency, 4K output, web grounding — are available in a Flash model at half the price. This compression of the premium-to-default timeline is consistent with the broader pattern in AI: capabilities that were differentiated last quarter become table stakes this quarter.
Provenance Is Becoming a Baseline Requirement The dual SynthID + C2PA approach Google is deploying is not unique to Nano Banana 2 — it applies across Google’s generative media outputs. But making it mandatory and automatic in the default image model sets an expectation that will be increasingly hard for competing models to ignore. As regulatory frameworks around AI-generated content develop in the EU, US, and elsewhere, built-in provenance tooling will shift from a differentiator to a compliance checkbox.
Ecosystem Integration Matters More Than Peak Quality Google’s competitive advantage with Nano Banana 2 is not primarily that it produces the best images (though by some benchmarks it currently ranks first). It is that it is the default in Google Search, Google Ads, Gemini, Flow, and Google Cloud simultaneously. Distribution at this scale changes the competitive dynamics significantly. Competing models may match or exceed the quality, but they cannot replicate Google’s integration footprint in the near term.
The Cost Curve Is Bending VentureBeat’s analysis describes Nano Banana 2 as the point where AI image generation transitions “from a creative novelty into a production-ready infrastructure component.” The 50% price reduction from Pro to Flash — at comparable quality across most use cases — makes the ROI case for production-scale AI image workflows measurably cleaner. For teams that have been watching the space but not yet deploying at scale, the pricing signal from this launch is meaningful. Source
The February 2026 launch of Nano Banana 2 marks a specific moment in AI image generation: the point at which the cost and speed trade-offs that kept high-quality generation out of most production pipelines were directly addressed by the leading model family in the space. By bringing Gemini 3.1 Flash’s speed to Nano Banana Pro’s feature set — at half the API price, with a unique image-search grounding capability, and across Google’s full product ecosystem — Google has made it considerably easier for marketers, developers, and enterprise teams to deploy AI image generation at the scale their workflows actually require. Whether you are an individual creator in the Gemini app, a developer building an API-powered application, or a media brand managing a global campaign pipeline, the practical question has shifted from “Can we afford good AI image generation?” to “How do we build the right workflow around it?” [Sources: Search Engine Land, Google Blog]
Frequently Asked Questions: Google Nano Banana 2
Q1: What is Google Nano Banana 2 and when was it released?
Google Nano Banana 2, officially known as Gemini 3.1 Flash Image (model ID: gemini-3.1-flash-image-), is Google DeepMind’s latest AI image generation and editing model.

Nano Banana 2 supports maintaining the resemblance of up to 4 characters and the fidelity of up to 10 reference objects, allowing a total of up to 14 reference images in a single workflow. This is useful for storyboarding, product catalog generation, and any narrative or brand asset workflow requiring visual consistency across multiple subjects. (Nano Banana Pro supports 5 characters and 6 objects with a maximum of 11 reference images — a different allocation that prioritizes character depth over object breadth.)
Q6: Can Nano Banana 2 generate accurate text inside images?
Yes. Accurate text rendering is one of the most improved capabilities in the Nano Banana 2 model. It can generate legible, stylized text within images — suitable for marketing mockups, greeting cards, infographics, event posters, and branded creative assets. It also supports in-image text translation, allowing you to take an image with text in one language and prompt the model to translate and re-render the text in another language while preserving the surrounding visual composition.
Q7: What is real-time web search grounding and how does it work in Nano Banana 2?
Web search grounding means Nano Banana 2 can use live Google Search results to inform its image generation — not just its training data. For example, if you ask it to depict a specific building, current product, or real-world scene, it can search for visual and factual references in real time and incorporate that information into the output. Nano Banana 2 uniquely also supports Google Image Search grounding, allowing it to search for images specifically and use retrieved visuals as reference context. This is not available in Nano Banana Pro at this time.
Q8: Does Nano Banana 2 have AI watermarking? How does it work?
Yes. All images generated by Nano Banana 2 are automatically embedded with SynthID, Google DeepMind’s invisible digital watermark technology. SynthID is embedded in the image data itself and persists through common modifications like cropping, compression, and filtering. Nano Banana 2 images also carry C2PA Content Credentials, an industry-standard metadata format that records contextual information about how the content was created. Together, these tools allow both identification of AI-generated images and attribution of the creation process — relevant for compliance, media verification, and brand trust contexts.
Q9: How do I access Nano Banana 2 as a developer?
Nano Banana 2 is available in preview via the Gemini API using model ID gemini-3.1-flash-image-.

The Artificial Analysis leaderboard is updated continuously as new model versions are submitted.
Q12: Can Nano Banana 2 be used for Google Ads creative?
Yes. Nano Banana 2 is now live in Google Ads as of the launch date, powering the AI image suggestions that appear when building campaigns. This means that when Google Ads surfaces AI-generated creative options during campaign creation, those suggestions are generated by Nano Banana 2 rather than an earlier model.
Q13: What happened to the original Nano Banana after Nano Banana 2 launched?
The original Nano Banana (Gemini 2.5 Flash Image) remains available via the Gemini API as a separate model (gemini-2.5-flash-image). It is designed for maximum speed and lowest cost in high-volume, low-latency tasks where visual quality is a secondary consideration to throughput. In the Gemini app, Nano Banana 2 has replaced it as the default, but both models remain accessible to developers through the API.
Q14: Does Nano Banana 2 support multi-turn image editing conversations?
Yes. Multi-turn (conversational) image editing is a core capability of Nano Banana 2 and the recommended workflow for iterative image development. You can generate an image, then continue the conversation with follow-up prompts to modify specific elements, change the language of embedded text, adjust the aspect ratio, or refine compositional details — with the model maintaining context from previous turns. This is supported in the Gemini API via the Chat interface (client.chats.create()).
Q15: What is Google Flow and how does Nano Banana 2 integrate with it?
Google Flow is Google’s AI-powered filmmaking tool designed for creating cinematic video clips and scenes using generative AI models. As of the Nano Banana 2 launch, the model is the default image generation engine in Flow, available at zero credits for all Flow users regardless of subscription level. This integration means creators using Flow for AI video production can access Nano Banana 2-quality visuals without additional credits or costs within that product.
Q16: What are the key use cases for Nano Banana 2 in enterprise settings?
Enterprise use cases where Nano Banana 2 provides the most measurable value include: localized marketing asset generation at scale; e-commerce product photography transformation; branded social media content pipelines; infographic and data visualization production grounded in real-time data; storyboard development for video and campaign pre-production; application UI/UX prototyping; and high-volume programmatic creative for advertising campaigns. The model has been tested and deployed by WPP (with Unilever), Adobe Firefly, Figma/Weavy, Notion, and Whering prior to launch.
Q17: Is Nano Banana 2 safe to use for commercial and brand assets?
Google’s API terms permit commercial use of Nano Banana 2 outputs. All generated images carry SynthID watermarks and C2PA Content Credentials, which support transparency and accountability in commercial contexts. As with all AI-generated content, users are responsible for reviewing outputs for accuracy and ensuring they do not infringe on third-party rights. For regulated industries, the C2PA metadata provides an auditable record of AI involvement in content creation. Google’s standard Prohibited Use Policy applies to all API usage.
Q18: What is the “Thinking mode” in Nano Banana 2 and when should I use it?
Nano Banana 2 supports a configurable “Thinking mode” with two levels. In Thinking mode, the model generates intermediate “thought images” internally — reasoning through composition, lighting, and spatial relationships before producing the final output. This improves quality on complex, multi-layered prompts at the cost of slightly longer generation time and some additional thinking token charges. For straightforward prompts or high-volume batch generation where speed matters most, minimal or no thinking is appropriate. For complex compositions, detailed infographics, or multi-reference workflows, enabling thinking produces measurably better adherence to the prompt.
