Question 1

Is Nano Banana 2 the same as Gemini 3.1 Flash Image?

Accepted Answer

Yes. Nano Banana 2 is fal.ai's branding for Google's Gemini 3.1 Flash Image model. The official Google API model ID is gemini-3.1-flash-image-preview. Both names refer to the same model.

Question 2

Does Nano Banana 2 have the same character consistency as Pro?

Accepted Answer

Yes. Both models support up to 5 reference characters and 14 objects per scene. The prompting techniques from the Pro guide — identity lock phrases, the one-change rule, feature locking — apply identically to NB2.

Question 3

Can I still use Nano Banana Pro after today's launch?

Accepted Answer

Yes, if you have a Gemini Pro subscription. Access it via the three-dot regenerate menu in the Gemini app. In the API, use model ID gemini-3-pro-image-preview. Pro is not going away; it is just no longer the default.

Question 4

What changed in text rendering between Pro and Nano Banana 2?

Accepted Answer

Pro achieves ~94% text accuracy. NB2 achieves ~90%. Both use character-level LLM validation before diffusion rendering, which is why both beat Midjourney v7's ~71% by a wide margin. For most text use cases, NB2 is sufficient. For precise typographic work such as logos or signage, Pro is the safer choice.

Question 5

Is the $0.039 pricing confirmed?

Accepted Answer

This is preview pricing based on Apiyi and WaveSpeed documentation from launch day, February 26, 2026. Final GA pricing has not been confirmed by Google. Monitor the official Gemini API pricing page before building production cost estimates into any project.
