Gemini Image

The Gemini image family ranges from the fast Gemini 2.5 Flash Image to Gemini 3.1 Flash and Flash Lite for efficient current workflows, plus Gemini 3 Pro Image for complex asset production. Capabilities vary by version: output size, aspect ratios, Search grounding, thinking, and the number of reference images are not interchangeable. Preview entries remain in the catalog for historical links; use their stable replacements for new work.

How to use this model

  1. 1

    Choose Flash for balanced iteration, Flash Lite for simple high-volume work, or Pro for complex layouts and demanding text.

  2. 2

    Describe the image as a complete scene: subject, action, environment, composition, lighting, style, and exact visible wording.

  3. 3

    When editing is available, upload clean references and explain what must be preserved and what may change.

  4. 4

    Set an aspect ratio and supported output size before generation; higher resolution does not replace a precise composition prompt.

  5. 5

    For text-heavy graphics, finalize the wording first and verify every label in the rendered image.

Nano Banana 2

Gemini 3.1 Flash Image is Google's balanced Nano Banana 2 model for high-quality image creation at low latency. It supports multiple output sizes up to 4K, expanded aspect ratios, thinking, and grounding with Google Search, including image search. This catalog entry is best for current general-purpose generation when both speed and capable composition matter.

Try now

Properties

  • Supports 0.5K, 1K, 2K, and 4K output choices.
  • Supports thinking and Google Search grounding.
  • Stable replacement for the earlier 3.1 Flash Image preview entry.

How to use this model

  1. 1

    Describe the full composition and exact text before choosing output controls.

  2. 2

    Select an aspect ratio and 0.5K, 1K, 2K, or 4K size appropriate to the target.

  3. 3

    Use Search grounding only when the image depends on current or verifiable information.

  4. 4

    For text-heavy work, settle wording first and give each label a clear location.

  5. 5

    Verify text, grounded facts, and fine detail in the final resolution.

2 LiteAvailable

Nano Banana 2 Lite

Gemini 3.1 Flash Lite Image is the efficient 1K member of the current Nano Banana family. It supports generation and editing with image references and common aspect ratios, but does not include the Search grounding available in the full Flash model. Choose it for interactive or high-volume 1K work with straightforward instructions.

Try now

Properties

  • Supports text-to-image and reference-image editing in Omnipix.
  • Outputs 1K images and does not use Search grounding.

Best for

  • High-volume image generation
  • Low-latency interactive image editing

Avoid for

  • 2K or 4K output
  • Workflows requiring search grounding

Tips

  • This model supports only 1K output.
  • Use up to 14 object reference images.

How to use this model

  1. 1

    Use a direct prompt with subject, composition, lighting, and style.

  2. 2

    Add references for editing and explain what must be preserved.

  3. 3

    Choose one of the supported aspect ratios for the 1K result.

  4. 4

    Keep each edit instruction narrow enough to evaluate clearly.

  5. 5

    Move to full Flash or Pro if the task needs Search grounding, larger output, or more complex production reasoning.

Nano Banana Pro

Gemini 3 Pro Image is designed for professional asset production and complex instructions. It uses thinking to refine composition, supports Search grounding, and can render high-resolution imagery up to 4K with strong text capabilities. In this catalog entry, use it for text-to-image work that benefits from careful planning rather than the fastest iteration.
