A post points to a possible Nano Banana 2.5 Flash reference in an update described as the latest Gemini Notebooks update for iOS. In a post on X, @lyraxana says the update contains the identifier IMAGE_GENERATION_GEMPIX_2P5_FLASH and links it to “spicy-mayo,” identified in the post as Nano Banana 2.5 Flash. Source on X

The identifier may indicate an internal reference to an image-generation model or integration, but the supplied post does not establish how it is being used.

What the identifier suggests

IMAGE_GENERATION_GEMPIX_2P5_FLASH appears to combine a description of an image-generation function with the labels “GEMPIX” and “2P5_FLASH.” Based on the post’s interpretation, the identifier refers to Nano Banana 2.5 Flash, also called “spicy-mayo.”

The post does not establish whether the identifier represents an active feature, an experiment, a placeholder or another internal implementation detail. It also does not explain what “spicy-mayo” means beyond the interpretation provided in the post.

Is Nano Banana 2.5 Flash available in Gemini Notebooks for iOS?

No public availability is confirmed by the supplied evidence. The report does not provide a publication date, app version, release date, rollout details, regional information, access requirements or pricing. It also does not include a screenshot or demonstrate that iOS users can select Nano Banana 2.5 Flash or generate images through Gemini Notebooks.

The available material provides no information about the model’s image-generation capabilities, performance or supported users. It therefore supports only a narrower conclusion: the reported iOS update contains an identifier that the post interprets as a reference to Nano Banana 2.5 Flash.

Until an official announcement or direct evidence of a user-facing feature is available, readers should treat the identifier as a reported internal reference rather than confirmation that Nano Banana 2.5 Flash is available in Gemini Notebooks for iOS.
