. This model is specifically optimized for coding tasks and general use, featuring an impressive 1 million context limit that significantly expands its processing capabilities.

The current Gemini 2.5 Pro, despite being eight months old, remains competitive in the market with a 63.8% score on SWE-Bench Verified, the industry standard for agentic code evaluations. However, it trails behind Claude Sonnet 4.5's 77% performance, suggesting room for improvement that Gemini 3 Pro aims to address

. The model also features improved text rendering within images and better angle and viewpoint control, addressing common pain points in AI-generated content.

On-Device Processing and Accessibility

A notable advancement in Nano Banana 2 is its lightweight design enabling on-device functionality

5

. This reduces dependency on cloud-based processing, enhances data privacy, and ensures faster processing times while maintaining high-quality output. The feature allows users to generate professional-grade images without constant internet connectivity.

Currently, a preview version is available on Media.io through subscription access, with the full release scheduled for November 11, 2025
