v1 text to image: write a prompt → pick aspect ratio and output format → generate → download from history.

v1 image to image: upload 1–10 images → describe the edit → set ratio and format → generate.

v1 Pro: upload 1–10 reference images → write prompt → choose 1K/2K/4K and aspect ratio → generate.

v2 Nano Banana 2: write a long prompt (up to 20k chars) → optionally add 0–14 images → set resolution, ratio, and format → generate.

When to pick v1 vs v2: use v1 for fast prompt-only drafts, dedicated I2I edits, or mandatory-reference Pro 4K; use v2 for 20k-character briefs or optional multi-reference in one workflow.
