Nano Banana 2 / Pro

Nano Banana 2

Google’s Nano Banana 2 is the second-generation Gemini image generation model, designed to deliver more realistic visuals, stronger text rendering, and improved editing control compared to its predecessor, positioning it as a more production-ready creative engine inside Google’s AI ecosystem.

Pros:

• Improved photorealism and detail consistency over the previous generation

• Better in-image text rendering and layout handling

• Tighter integration with Gemini workflows for conversational image creation and editing

• More reliable multi-object and complex scene generation

Cons:

• Still dependent on prompt quality for best results

• Competes in a crowded high-end image model market

• Advanced creative controls may require experimentation to master

Nano Banana 2: Command & Parameter Cheat Sheet

Version: 2.0 (Feb 2026)

Scope: Gemini App, AI Studio, and Pro API

1. Core Reference Triggers (@ Commands)

Command	Function	Syntax Example
@search	Triggers live Google Search Grounding for factual accuracy.	"Generate a schematic of @search[2026 Tesla Model S Interior]"
@acoustic	Generates synchronized material-specific audio physics.	"A ceramic bowl falling on wood floor @acoustic[shatter]"
@identity	Locks character consistency across multiple generations.	"Generate @identity[Character_1] in a futuristic Irvine library"
@translate	Native in-image text translation and localization.	"Update label text to @translate[Japanese]"
@fusion	Blends up to 14 reference images into a single lighting rig.	"Fuse @ref[1-8] with volumetric lighting @fusion[HDR]"

2. Advanced Thinking Parameters (Pro API)

These parameters allow you to control the "Reasoning vs. Speed" balance of the Gemini 3.1 architecture.

• --thinking_level [minimal|dynamic|high]

  • minimal: For rapid ideation (1s). Best for social media posts.

  • dynamic: Default mode. Automatically balances logic and speed.

  • high: For complex infographics, architectural renders, and fine text.

• --physics_engine [enabled|disabled]

  • Set to enabled to ensure shadows, reflections, and light fall-off respect real-world optical laws.

• --upscale [2k|4k|8k]

  • Directly outputs or upscales the generation to high-fidelity production resolutions.

3. Aspect Ratio Presets

Nano Banana 2 supports extreme aspect ratios for specialized marketing formats.

• --ar 8:1 / 1:8 (Ultra-wide Panoramas / Mobile Scroller Ads)

• --ar 4:1 / 1:4 (Website Banners / Story Posters)

• --ar 2.39:1 (Cinematic Anamorphic)

4. Best Practices for "Identity Lock"

To maintain 100% character consistency in a storyboard (Irvine Filmmaker Workflow):

1. Step 1: Generate your "Hero Shot" and save the Character ID.

2. Step 2: Use @identity[ID_Code] in all subsequent prompts.

3. Step 3: Use --thinking_level high to ensure facial micro-details (skin texture, freckles) do not drift during transitions.
