Google Nano Banana 2 is the flagship Gemini Image lineup — built on Gemini 3.1 Flash Image and Gemini 3 Pro Image — delivering native up-to-4K generation, opt-in web search grounding, and best-in-class text rendering, character consistency, and multi-image composition.
Nano Banana 2 is Martini's hosted name for Google's flagship Gemini Image lineup, rolled out worldwide on February 26, 2026. The base Nano Banana 2 model is built on Gemini 3.1 Flash Image and supports text-to-image plus image-to-image with up to 10 reference inputs; Nano Banana Pro upgrades to Gemini 3 Pro Image, accepting up to 14 reference images and maintaining character identity for up to 5 people in a single composition. All four variants generate natively at 1K, 2K, or 4K — pick higher resolutions for hero deliverables and lower ones for fast iteration. Premium tiers add roughly double the compute budget for faster turnaround on identical quality. Web search grounding is opt-in, letting the model pull live facts and references from Google Search when rendering real places, products, public figures, or current events. Output ships as JPEG or PNG across 15 aspect ratios — including portrait, landscape, square, panoramic 21:9, and ultrawide 8:1 / 1:8 strips. On Martini, drop a Nano Banana 2 node onto the canvas, wire reference images in directly, and chain outputs into FLUX Kontext for character consistency, Imagen 4 for lightweight drafts, or any video / audio node to build complete multimodal pipelines without leaving the canvas.

Get Started FreeNano Banana 2 is Martini's hosted name for Google's flagship Gemini Image lineup (Gemini 3.1 Flash Image and Gemini 3 Pro Image), released February 26, 2026. It adds native 4K, opt-in web search grounding, multi-image composition (up to 14 references on Pro Premium), and 5-person character consistency. The separate Martini Imagen 4 family covers the standard Imagen 4 model and the legacy Nano Banana model — useful for lightweight drafts, but without web grounding or the new 4K / multi-image features.
Premium tiers (Nano Banana 2 Premium, Nano Banana Pro Premium) double the compute budget for faster turnaround. Use them for time-sensitive deliverables, batch jobs (counts of 2–4 per request), or when you need the maximum 14 reference inputs available only on Pro Premium. For exploratory work, the standard tiers ship the same model quality.
Grounding lets the model pull live information from Google Search while rendering — useful for real places, products, public figures, current events, brand assets, or anything that benefits from real-world references. For stylized art, fantasy, or generic compositions, leave it off; for editorial, news, e-commerce, or location-accurate scenes, enabling it usually pays off in factual accuracy.
Google Imagen 4 is the lightweight entry point to Google's photorealistic image stack on Martini. Use it for fast drafts and steady photorealistic output before upgrading winning prompts to the dedicated Nano Banana 2 lineup.

Midjourney v7 is the most recognizable AI image generator, with the strongest aesthetic signature in the category. On Martini you get V7 for photoreal and painterly work, Niji 7 for anime, Omni Reference for character lock-in, and Stylization, Variety, and Weirdness sliders for fine control — all from the canvas, no Discord required.
