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.
This page covers the standard Google Imagen 4 model plus the legacy Nano Banana variant — both available on Martini for lightweight, fast-turnaround workflows. Imagen 4 offers Fast, Standard, and Ultra tiers with reliable photorealism, natural lighting, and accurate material textures across the standard set of aspect ratios. The legacy Nano Banana model is the original Gemini Image variant kept around for in-flight projects and prompt libraries built before the February 2026 Nano Banana 2 launch — new work should generally start on Imagen 4 or jump directly to the dedicated Nano Banana 2 family for native 4K, web search grounding, and multi-image composition. Both variants on this page excel at product photography, architectural visualization, and lifestyle imagery — chain them into Martini's video, audio, and 3D nodes to build complete creative pipelines without leaving the canvas.
| Variant | Description |
|---|---|
| Imagen 4 | Standard Imagen 4 model with Fast / Standard / Ultra speed-quality tiers and solid photorealistic quality. |
| Nano Banana | Legacy Nano Banana model, kept available for projects and prompt libraries built before the Nano Banana 2 launch. |

Get Started FreeThis page covers the standard Imagen 4 model and the legacy Nano Banana variant — Martini's lightweight route into Google's photorealistic stack. The dedicated Nano Banana 2 family covers the flagship Gemini 3.1 Flash Image and Gemini 3 Pro Image lineup launched in February 2026, with native 4K, web search grounding, multi-image composition, and premium tiers. Use Imagen 4 for fast drafts; use Nano Banana 2 for hero finals.
Use Imagen 4 with its Fast / Standard / Ultra tiers for quick prompt validation, A/B testing, and high-volume drafts where speed and lightweight output matter. Switch to Nano Banana 2 when you need 4K output, web search grounding for real-world accuracy, multi-image composition with up to 14 references, or 5-person character consistency.
Only if your existing project or prompt library was specifically tuned to its look. For any new work, start with Imagen 4 (lightweight drafts) or Nano Banana 2 (flagship features). The legacy variant is kept available so in-flight projects don't break.
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.
