Gemini 2.5 Flash Image. Edit images by asking.
Google's flash-tier image model, and Treza's default. Generate from text, then refine by telling it what to change: swap the background, keep the character, fix the label. Fast and inexpensive enough to iterate freely.
- Text and image input
- Conversational edits
- Treza default
Gemini 2.5 Flash Image, widely known as Nano Banana, made conversational image editing mainstream. It takes images as input alongside text, so a generation is never final: change the background but keep the product, put the same character in a new scene, brighten the shot without re-rolling it. Subjects stay consistent across edits, which is the hard part.
It is Treza's default image model because speed and price match how people actually work: many small steps. In a pipeline it becomes an editing stage, taking an upstream generation or an uploaded photo plus an instruction, and in chat it powers quick iterate-until-right sessions that cost cents.
Instruction-based editing
Feed it an image and a sentence. Swap backgrounds, remove objects, restyle scenes, and the untouched parts stay untouched.
Character consistency
The same person, mascot, or product carries across generations and edits, keeping a series looking like a series.
Multi-image fusion
Combine several input images into one scene: your product into a lifestyle photo, your logo onto a mockup.
Flash speed, flash price
Fast generations at a low per-image cost. A $5 pack covers dozens of generations at this tier.
What to make with Gemini 2.5 Flash Image
Real prompts, and what comes back. Every one runs in Treza chat or as a node on the canvas.
“A product shot of this bottle (attached) on a beach at sunset”
Your actual product composited into a new scene.
“Same image, but make it winter and add falling snow”
An edit that changes the season and nothing else.
“Remove the passerby on the left”
A clean plate with the background rebuilt naturally.
“Put this mascot in a chef hat flipping pancakes”
Your character, on model, in a new scenario.
“Merge these two photos: the watch from A on the wrist in B”
A believable composite from two references.
“Make a 9:16 crop-safe version with room for text at the top”
A layout-aware variant for stories and ads.
Gemini 2.5 Flash Image is one node on a canvas
Chain it with language, image, and video models, then publish the whole pipeline as an API.
- Step 01
Draft the brief
A language model node expands a one-line idea into a detailed, on-brand prompt before it ever reaches the model.
- Step 02
Generate with Gemini 2.5 Flash Image
Run variants in parallel, compare against other models on the same prompt, and keep every result in run history.
- Step 03
Publish it as an API
The pipeline becomes a versioned endpoint. Your product calls it with the typed /invoke API or any OpenAI SDK.
Gemini 2.5 Flash Image, answered
Is Gemini 2.5 Flash Image the same as Nano Banana?
Yes. Nano Banana is the nickname Gemini 2.5 Flash Image picked up at launch, and it stuck. Same model, and on Treza it appears under its official name in the model picker.
Can it edit images I upload?
Yes. It accepts image input alongside text, so you can upload a photo and describe the change. Edits are targeted: the model changes what you asked for and preserves the rest of the frame.
When should I use FLUX.2 Pro or Seedream 4.5 instead?
Use Gemini 2.5 Flash Image for iteration, edits, and volume. Reach for FLUX.2 Pro when a final asset needs maximum photorealism and typography, or Seedream 4.5 for high-resolution output and complex multi-image composition. Swapping is one dropdown on the node.
How much does Gemini 2.5 Flash Image cost on Treza?
Treza uses prepaid credits with no subscription. Each image is charged at Gemini 2.5 Flash Image's rate from your balance, and only successful generations are charged. Credit packs start at $5 and never expire.
Can I call Gemini 2.5 Flash Image through an API?
Yes. Build a pipeline that uses Gemini 2.5 Flash Image and publish it as a versioned HTTP endpoint. Call the typed /invoke API from your product, or point any OpenAI SDK at the OpenAI-compatible endpoint. If a better model ships later, swap it on the node without changing the API your product calls.
