What is Nano Banana?
Nano Banana is the unofficial name (originated as a team nickname at Google DeepMind, later confirmed publicly) for Gemini 2.5 Flash Image, released August 26, 2025 and GA on Vertex AI in October. On CVY.AI, it is available as a 3-credit option for 1K images.
Choose it from the model selector for character-consistency work and prompt iteration.
Use it for 1K drafts, multilingual prompts and reference-guided edits. Try the same prompt with another model if the output does not fit the task.
What Nano Banana is good at
- ▸
1K drafts and iteration
Generate or edit a 1K image for 3 credits on CVY.AI. Waiting time depends on the provider and current demand.
- ▸
Character consistency across prompts
Supply a reference image when you want the output to follow a character or product. Check the result carefully: identity and small details may change between generations.
- ▸
Multi-image fusion
Blend multiple reference images into one output. Useful for "this character + this setting + this lighting" composites that would normally take three rounds of prompt-editing in a one-shot model.
- ▸
Multilingual prompt understanding
Write prompts directly in English, Chinese, Japanese or Korean. Results vary by prompt and subject.
- ▸
3-credit image generation
Generate 1K images for 3 credits each. GPT Image 2 at 1K is the lowest-credit option at 2 credits per image.
