nano banana lite FAQ: Speed & Implementation
Common questions about the nano banana lite model, covering latency, pricing, and specific multimodal capabilities.
How fast does nano banana lite generate images?
The nano banana lite model is built for speed, generating 1K resolution images in approximately 4 seconds. This makes it 2.7 times faster than the standard Gemini 3.1 Flash Image model, allowing for near real-time visual responses in interactive applications.
What is the pricing for nano banana lite on GPTProto?
Using nano banana lite is highly cost-effective. Image output is priced at $0.034 per 1K-resolution image. For text and image inputs, the rate is $2.00 per 1M tokens, with a 50% discount available on input tokens for cached context hits during long sessions.
Does nano banana lite support character consistency?
Yes, nano banana lite inherits the family strength for character consistency, achieving an internal benchmark of 88%. This is significantly higher than competing lite models, making it ideal for maintaining character identity in storytelling or marketing.
Can nano banana lite perform visual OCR tasks?
Absolutely. nano banana lite is optimized for high-throughput visual OCR. It can scan large batches of documents or screenshots, specifically excelling at extracting tabular data and identifying UI components for automated testing or data entry.
What are the limitations of the lite model?
While nano banana lite is excellent for speed and cost, it is not optimized for multi-turn sequential editing or artistic masterpieces. For ultra-high-resolution fine art or complex mathematical proofs, we recommend the Pro version of the model family.
Is my data used to train the nano banana lite model?
No. GPTProto.com ensures that enterprise customers are protected by a Zero-Data-Retention policy. Your inputs and generated images are not used to train the underlying Google DeepMind models, ensuring your proprietary data remains private.
