  • Prompts allow 20,000 characters, and each request accepts up to 14 JPG, PNG, or WebP images.
  • The current public source request schema has no `google_search`; Kyeo neither displays nor sends a web-search field.
  • Kyeo currently exposes only 1K, 2K, and 4K, priced at 5, 8, and 12 credits.

At a glance

What is this model like?

Google calls Nano Banana 2 Gemini 3.1 Flash Image and positions it as an efficient all-purpose image model. public source interface uses its own `nano-banana-2` identifier without publishing the public source Gemini version on the endpoint page. This page therefore uses Google material for model background and public source interface plus Kyeo configuration for the controls users can actually select.

What it does best
Among Kyeo's current Nano Banana options, this page is distinguished by up to 14 images, a 20,000-character prompt, 15 aspect-ratio choices, and 1K, 2K, or 4K output tiers; there is currently no web-search control.
Best for
It is a practical candidate for edits built from several clearly assigned references, or infographics and covers with detailed text and layout constraints. In-image text, subject details, and factual claims still need review, and the model cannot retrieve live web information.
Why use it on Kyeo AI
Aspect ratio, resolution, and output format are visible in one form, and Kyeo calculates credits from the chosen resolution. You can validate composition and instruction following at 1K before paying for 2K or 4K.

Selection guide

Use these decision points when choosing a model.

1
Choose it when you need more references or resolution tiers

Nano Banana 2 is worth testing when the brief needs more references than the base route's recommended working set, extreme 4:1, 1:4, 8:1, or 1:8 ratios, or explicit 2K or 4K output. Obtain any recent facts from reliable sources first.

2
Compare other models by controls and test output

For basic generation or editing at a fixed 3 credits, compare standard Nano Banana. When 8 images are enough, run the same prompt and material through Pro. None of these current site options provides a web-search control.

3
Build a 1K baseline with a small reference set

Begin with 1 to 3 essential images and a 1K request. Raise resolution or add inputs after the source roles and composition are working. If the brief needs recent information, obtain and verify it from reliable sources before writing the prompt.

Practical usage insights

Practical guidance based on public sources, current on-site limits, and representative tasks.

A shared product name does not disclose the public source service version

Google maps Nano Banana 2 to stable `gemini-3.1-flash-image`, while the public source interface publishes `nano-banana-2`.

Direct Gemini features and Kyeo controls are different scopes

Google's model also supports 0.5K, image-search grounding, PDF or video context, and Thinking, but Kyeo AI does not currently display those controls. This page promises only the features supported by both the Kyeo AI form and the public source interface.

Credit differences are not a quality ranking

Nano Banana 2 currently costs 12 credits at 4K and Pro costs 14 at 4K. That is a Kyeo pricing difference, not evidence about image quality, text accuracy, reference adherence, or editing stability; compare those with the same source material.

Capabilities

Text generation and reference-guided editing

Kyeo uses Nano Banana 2 for both text-only generation and reference-guided editing. You can upload up to 14 reference images, but the limit is not a recommendation to fill every slot.

Web search is currently unavailable

The current public source request schema has no `google_search`, so Kyeo neither displays nor sends a web-search parameter. Search capabilities of Google's direct model do not become Kyeo features; weather, sports, and recent events must be verified separately from reliable sources.

Aspect ratio, resolution, and output format

The form has 15 aspect-ratio choices, including auto, 4:1, 1:4, 8:1, and 1:8. Output options are 1K, 2K, or 4K and JPG or PNG; Google's 0.5K tier is not exposed on Kyeo.

Prompt and credit boundaries

Prompts allow 20,000 characters, but that is a ceiling rather than a target. A request currently costs 5 credits at 1K, 8 at 2K, or 12 at 4K, so it is sensible to validate instructions at the lower tier first.

Use cases

Drafts that need recent public information

Obtain weather, sports, or recent-event information from reliable sources first, then place the verified dates, numbers, and wording in the prompt. The current model cannot browse, and every map, chart, and piece of text still requires review.

Product or brand visuals with several references

Assign separate images to the subject, material, setting, and layout. When identity, product accuracy, or brand rules matter, inspect details that were not meant to change.

Infographics or covers with text and layout constraints

Break out the title, hierarchy, composition, palette, and protected elements. Google reports better multilingual text rendering for this model, but Kyeo output still requires line-by-line proofreading.

Prompt tips

Verify time-sensitive facts outside the model

There is currently no web-search control. When an image depends on recent public information, obtain and verify facts from reliable primary sources before writing the prompt; do not treat the generated image as evidence.

Start with a small, clearly assigned image set

Begin with 1 to 3 images and identify which one supplies the subject, material, pose, setting, or layout. Add images only when the result is controllable and information is genuinely missing, so the references do not conflict.

Turn a long prompt into testable sections

The 20,000-character allowance is a limit, not a goal. Separate subject, composition, copy, reference roles, protected details, and exclusions, then test at 1K before choosing a higher output tier.

Why choose it

Supports both text-to-image generation and reference-image editing on one page.
The current public source request schema has no web-search field, and Kyeo neither displays nor sends one.
The form offers 15 aspect-ratio choices and 1K, 2K, or 4K output.
A 20,000-character prompt and up to 14 images leave room for complex constraints.

What to know first

For routine generation or editing at a fixed 3 credits, the base Nano Banana workflow is lighter.
The current model cannot browse for live information, so time-sensitive facts must be verified outside the model.
Search capabilities of Google's direct model do not become features of the current Kyeo integration.
Kyeo does not expose the direct API's 0.5K tier, image-search grounding, PDF or video input, or Thinking controls.

Credit usage

Current Kyeo AI pricing is 5 credits at 1K, 8 credits at 2K, and 12 credits at 4K.

Budget tip

Before batch generation, run an A/B test with the same assets across the current model and alternatives to validate quality and avoid wasting credits.
