Google launches cheaper, better Nano Banana 2.1 image model
Google has released Nano Banana 2.1, an update to its AI image generation and editing model built on Gemini 3.6 Flash. The new version claims improvements in visual design, mask-based editing, subject consistency, and text rendering, while also reducing API pricing by roughly half for 1K and 2K outputs. It supports up to 14 reference images, four consistent people, and ten objects, and offers 1K, 2K, and 4K output options. However, early community feedback on Reddit suggests mixed results, with some users reporting worse instruction following and more restrictive behavior compared to version 2.0. Google acknowledges remaining weaknesses in small text, long passages, spatial reasoning, and factual accuracy. The model is available across Gemini app, Google AI Studio, Gemini API, AI Mode, Google Ads, Flow, and Stitch. Google continues to apply SynthID and C2PA content credentials for AI-generated image provenance.
Google's launch of Nano Banana 2.1 represents a significant update to AI image generation technology with halved pricing, which could accelerate adoption in advertising creative workflows and impact the AdTech ecosystem for visual content production.

Google Unveils Nano Banana 2 for Faster Image Generation
Google announced Nano Banana 2 (technically Gemini 3.1 Flash Image), an updated image-generation model that creates more realistic images faster than prior versions. Nano Banana 2 will become the default image model in the Gemini app across Fast, Thinking, and Pro modes, and will be used by default in Google Search (via Lens and AI Mode) across 141 countries, as well as in the Flow video-editing tool. The model supports resolutions from 512px to 4K, preserves character consistency for up to five characters and fidelity for up to 14 objects, and produces richer lighting, texture, and detail. Developers can preview the model via the Gemini API, Gemini CLI, Vertex API, AI Studio, and Antigravity. All generated images will carry Google’s SynthID watermark and will interoperate with C2PA Content Credentials; Google says SynthID has been used over 20 million times since its November launch.
Nano Banana 2: Faster AI Images with Gemini Knowledge
Google unveiled Nano Banana 2, an AI image-generation model that blends Gemini’s real-world knowledge with capabilities to render visuals directly from text, enabling faster creation of infographics and marketing mockups. The update adds improved image-generation performance categories, including character consistency up to five and object consistency up to 14, better instruction-following, and direct control over asset specs and templates. It supports new aspect ratios (4:1, 1:4, 8:1, 1:8) and showcases enhanced lighting and textures. Rollout spans multiple Google environments: Nano Banana 2 is available in the Gemini App for AI Pro/Ultra, integrated in AI Mode, Lens, browser, and the app; Preview in AI Studio and Vertex AI via the Gemini API; and for Flow users as a base model with no credits required. An Ads feature allows marketers to generate asset suggestions for campaigns. Pricing is 60 USD per million tokens, with per-image costs ranging from $0.045 (512px) to $0.151 (4K). SynthID and interoperable C2PA Content Credentials are included to indicate AI usage; Pratham Kumar, an AI researcher, notes potential handwriting replication concerns.
Google Unveils Nano Banana 2: Faster, Smarter AI Image Generator
Google rolled out Nano Banana 2, an update to its popular AI image generator family. The original Nano Banana launched in August and Nano Banana Pro debuted in November built on Gemini 3 Pro. Nano Banana 2 integrates real-time knowledge from Gemini to improve factual accuracy, increases generation speed, enhances instruction following, and produces more precise text renderings intended for use cases like marketing mockups and greeting cards. Google will keep Nano Banana Pro available for tasks needing maximum factual fidelity while positioning Nano Banana 2 for rapid generation and image-search grounding. The update replaces the predecessor across Gemini’s Fast, Thinking and Pro tiers. The launch occurs amid broader industry attention on generative image/video tools and related copyright concerns.
