The launch follows a shifting development cycle that started June 16 with a checkpoint known as instant-ramen, or Nano Banana 2 Lite. The model evolved through versions like instant-ramen-v2 and spicy-mayo—originally designated as Nano Banana 2.5 Lite—before being rebranded as Nano Banana 2.1 Flash for the final rollout. Vertex partners had received early access to the 2.5 version on Sept. 18.
