A dash means Google lists no price for that size. Nano Banana Pro charges the same for 1K and 2K images.
How Google prices images
Google charges for images as output tokens and publishes what that comes to per image. For example, a 1K image from Nano Banana 2 uses 1,120 tokens, priced at $60 per million image tokens, which is about $0.067. Nano Banana 2.1 charges $30 per million image tokens, so the same size costs about $0.034.
- Nano Banana 2.1: $30 / $15 per 1M image tokens
- Nano Banana 2: $60 / $30 per 1M image tokens
- Nano Banana 2 Lite: $30 / $15 per 1M image tokens
- Nano Banana Pro: $120 per 1M image tokens, and each image you send in costs about $0.0011
None of these image models has a free tier on the Gemini API. With grounding on Google Search, Gemini 3 and newer models share 5,000 free search requests a month, then $14 per 1,000.
The first Nano Banana is gone
Google set 2 October 2026 as the shutdown date for Gemini 2.5 Flash Image, the original Nano Banana, and points users to Nano Banana 2 or Nano Banana 2 Lite.
Other image APIs
xAI lists Grok Imagine Image at $0.02 per image, Grok Imagine Image 2.0 at $0.04 and its quality mode at $0.05 (Grok API pricing). OpenAI prices its GPT Image models per token and points to a calculator in its image guide, so a per-image figure depends on size and quality.
