🎯 Pro Tip: If your use case doesn't require real-time results, I highly recommend using Batch mode—it's half price across all resolutions. 4K images drop from $0.151 to $0.076, which is almost the same as the standard 0.5K price.

Nano Banana 2 vs. Nano Banana Pro: Price Comparison

This is the comparison developers care about most. Both are official Google image generation models, but the pricing gap is significant:

An interesting discovery: Nano Banana 2's standard 1K price ($0.067) is exactly the same as Nano Banana Pro's Batch 1K price ($0.067). This means Nano Banana 2's real-time invocation costs the same as Nano Banana Pro's asynchronous batch processing. If you use Batch mode, Nano Banana 2's 1K image price drops to $0.034—just a quarter of Nano Banana Pro's standard price.

🎯 Migration Advice: Switching from Nano Banana Pro to Nano Banana 2 reduces image generation costs by at least 25-50% and text token costs by 70-80%. Through APIYI (apiyi.com), you can maintain access to both models for flexible comparison.

Nano Banana 2 vs. Competitors: A Full Pricing Comparison

Where does Nano Banana 2 stand in the AI image generation market? Here's a standard price comparison for 1K resolution against major competitors:

Analyzing Nano Banana 2's Price Positioning

At 1K resolution, Nano Banana 2's standard price of $0.067 sits in the middle of the market—slightly more expensive than DALL-E 3 ($0.04) and Flux Pro ($0.04). However, considering the following unique advantages, this pricing is very reasonable:

• Native 4K Support: Most competitors only support 1K, while Nano Banana 2 can output 4K directly.
• Google Search Integration: This is a exclusive capability that competitors don't have.
• Thinking Mode: You can enable deep reasoning for complex scenes.
• 14 Aspect Ratios: Far exceeds the ratio support of its competitors.
• Half-price Batch Mode: If you use Batch mode, the $0.034 price per 1K image is actually 15% cheaper than DALL-E 3.

🎯 Selection Advice: If you only need 1K images and are chasing the absolute lowest price, DALL-E 3 or Flux might be more suitable. But if you need 2K/4K HD, Chinese text rendering, Google Search knowledge integration, or a wide variety of aspect ratios, Nano Banana 2 is currently your best bet. We recommend using APIYI (apiyi.com) to access and compare multiple models simultaneously.
