At a glance

What is this model like?

This is a fixed-price generation and editing option with no resolution-priced tiers. Google's current Gemini API documentation still lists `gemini-2.5-flash-image` as stable; the retired identifier is the older preview `gemini-2.5-flash-image-preview`. Kyeo uses the current public source generation and editing identifiers, so actual capability is defined by this page's parameters and runtime results.

What it does best
Kyeo places Nano Banana's text-to-image and image-editing workflows on one page, but submission still uses a different current public source model ID depending on whether an image is uploaded. Its defining difference is a fixed 3-credit cost rather than higher-resolution tiers or search grounding.
Best for
Use it to create an image from text, add, remove, replace, or restyle parts of an existing image, or test a composition with a small set of clearly assigned references. Character, product, and brand consistency must be checked rather than assumed.
Why use it on Kyeo AI
The form exposes the current boundaries: a 5,000-character prompt, PNG or JPEG output, 11 aspect ratios, and up to 10 images on the editing route. Kyeo selects the matching generation or editing path automatically.

Selection guide

Use these decision points when choosing a model.

1
Choose it when a fixed request cost matters

If the brief does not require a 1K, 2K, or 4K tier or search grounding, a 3-credit generation or targeted edit is a low-commitment way to test the result before continuing.

2
Compare newer options for resolution or search

Kyeo's Nano Banana 2 and Pro are the relevant comparisons when you need explicit 1K, 2K, or 4K output tiers or search grounding. Use the same source image with GPT Image 1.5 to compare a different vendor's editing behavior.

3
Start with 1 to 3 references

For multi-image edits, assign a clear role to each input and begin with a small set. Add more only when the extra material is necessary and the result remains controllable; a 10-image limit does not mean 10 images will be more reliable.

Practical usage insights

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

An interface maximum is not a recommended input count

The current public source editing interface accepts up to 10 images, so a request can carry more source material. Google's Gemini 2.5 Flash Image guidance recommends no more than 3 inputs for better results. In practice, start with the smallest effective input set.

Legacy status does not mean the Kyeo route is offline

Google currently lists `gemini-2.5-flash-image` as stable and only `gemini-2.5-flash-image-preview` as retired. Kyeo uses a different current public source identifier, so the exact version mapping cannot be inferred from the name alone.

Capabilities

Text-to-image generation

When no image is attached, Kyeo sends the prompt to `Nano Banana`. You can choose an output format and aspect ratio, and the request costs a fixed 3 credits.

Natural-language image editing

Attaching an image switches the request to `Nano Banana`. You can describe what to preserve, remove, replace, or restyle, but each output still needs a visual check for instruction adherence.

Format, ratio, and input boundaries

The current workflow offers PNG or JPEG output and 11 aspect ratios. You can submit up to 10 reference images, but Google recommends no more than 3 inputs for better results with this model.

Use cases

Create a new image from a brief

Describe the subject, setting, composition, and visual treatment, then choose a landscape, portrait, or square aspect ratio for the first draft.

Make a targeted change to an existing image

Try adding or removing an object, replacing a background, adjusting color, or changing style. Manually verify untouched details when identity, product accuracy, or brand rules matter.

Compose from a small reference set

Provide separate references for the subject, material, or scene and name each role in the prompt. Begin with 1 to 3 images instead of treating the interface maximum as a target.

Prompt tips

Lead with the subject and the requested action

State what to create or change in one sentence, then list what must remain, what to replace, and what to avoid. Actions are easier to verify than a loose string of style adjectives.

Label the purpose of every reference

Identify which image supplies the subject, material, pose, or background, and start with 1 to 3 inputs. As the set grows, check for mixed-up or omitted elements.

Choose the ratio and format before submitting

Match 1:1, 16:9, 9:16, or another ratio to the intended placement, then select PNG or JPEG. Review text, hands, edges, subject features, and areas that were not meant to change.

Why choose it

Text-to-image generation and editing are available from the same page.
Both routes cost 3 credits per request, making the cost predictable.
Prompts allow 5,000 characters and the form offers 11 aspect ratios.
The editing route can accept multiple images with separately defined roles.

What to know first

Google currently lists `gemini-2.5-flash-image` as stable, but Kyeo uses an current public source identifier, so exact version equivalence cannot be assumed.
The current form has no 1K, 2K, or 4K output tier and no search grounding.
The 10-image upload limit is capacity, not a recommendation or a consistency guarantee.
Text, identity, product details, consistency, and rights still require human review.

Nano Banana Pro

Nano Banana Pro supports text-to-image generation and reference-image editing on Kyeo AI, with 1K, 2K, or 4K output. Each 1K or 2K request costs 8 credits, while 4K costs 14. Resolution is an output-size tier, not a guarantee of quality, accuracy, or detail.

Nano Banana 2

Kyeo AI offers text-to-image generation and reference-guided editing with Nano Banana 2. You can upload up to 14 reference images, choose from 15 aspect ratios, and output at 1K, 2K, or 4K. Those tiers currently cost 5, 8, and 12 credits, prompts allow 20,000 characters, and the current generation form does not offer web search.

GPT Image 1.5

GPT Image 1.5 on Kyeo supports text-to-image and image-to-image with three aspect ratios and medium/high quality. Image editing accepts up to 16 JPG, PNG, or WebP references at 10 MB each. Medium costs 4 credits and high costs 22 credits. GPT Image 1.5 is OpenAI's deprecated previous image model. Kyeo retains generation and editing access, but that availability does not make it OpenAI's current default choice.
