What it does.

01

Identity-preservation phrasing

Specific clauses Nano Banana 2 honors for keeping a face faithful across references.

02

Multi-reference patterns

How to phrase prompts when feeding 4-8 references — what gets emphasized.

03

Edit-instruction grammar

What the /edit endpoint takes literally vs interprets — surgical control.

04

Anti-pattern list

Phrasings that produce identity drift, deformed features, missing detail.

05

Aspect ratio cues

When to specify aspect explicitly vs let the model infer from references.

06

Studio direction language

Soft Rembrandt, golden hour, neon noir — what the model actually responds to.
