Nano Banana 2 specs: a Google AI image editor at a glance
Here's what sets Nano Banana 2 apart from the diffusion models in the lineup.
Instruction-following architecture
Unlike diffusion models that try to match a caption, Nano Banana 2 understands instructions. Tell it 'replace the jacket with a sweater' and that's what it does, without rewriting the face, background, or other elements.
Built-in identity preservation
Same face, same character, same product, preserved across multiple edits. Generate 10 variations of one subject without it drifting into 10 different people. Critical for character design and consistent product photography.
Aspect ratios, including extreme formats
Standard (1:1, 3:2, 2:3, 4:3, 3:4, 16:9, 9:16) plus wide cinematic (21:9), unusual (5:4, 4:5), and ultra-wide banner formats (4:1, 1:4, 8:1, 1:8). We surface a curated set of these in the UI.
Resolutions up to 4K
Choose 0.5K, 1K (default), 2K, or 4K output. 4K is suitable for print and large displays without external upscaling. Higher resolutions cost proportionally more credits.
Strict safety controls
Pinned to safety_tolerance level 2 (strict). Content violations rejected and credits auto-refunded. We pin this stricter than fal's default 4 because safety is more reliable than user goodwill.
Multi-image input for edits
Image-to-image edit endpoint accepts an array of up to 10 reference images. Useful for style transfer with multiple references, or for grounding edits in multiple views of the same subject.
What Nano Banana 2 does best for instruction-based photo edits
The tasks where Nano Banana 2 is the right tool, based on what we've seen work consistently in testing.
'Change just this one thing' edits
Outfit swap, hair color change, accessory add/remove, background switch, season/weather change, anywhere you want to modify one element while leaving the rest of the image alone. This is Nano Banana 2's specialty.
Character variations and consistency
Generate 6 poses of the same character, or the same product from different angles. Nano Banana 2 keeps the subject coherent. Most useful for game character design, brand mascots, and lookbook-style product shoots.
Product photo refinement
Take a basic product shot and make targeted improvements, 'change the background to a marble surface', 'add soft directional lighting from the left', 'remove the second product in the background'.
Headshot and portrait editing
'Change the suit to a turtleneck', 'remove glasses', 'change tie color to navy'. Nano Banana 2's identity preservation means the person still looks like the same person after the edit.
Photo restoration and modernization
'Sharpen the details', 'fix the lighting', 'change to portrait orientation while keeping the subject'. Subtle edits at low strength preserve the original character while polishing weaknesses.
Logo and icon variation
Generate horizontal, vertical, light-on-dark, and condensed versions of a logo from one source. Or generate icon variations (rounded, sharp, outlined) from one design.
Nano Banana 2 vs other AI image models: when to edit, not generate
When Nano Banana 2 is the right call, and when another model in the lineup fits the task better.
Use Z-Image Turbo for full-scene rewrites
If you want everything to change (different subject, different scene, different style), Nano Banana 2 won't go that far because it's trying to preserve. Z-Image Turbo at strength 0.85+ is the right tool for dramatic rewrites.
Learn more →Use GPT Image 2 for higher final quality
Nano Banana 2's outputs are good but not premium. For final marketing assets, GPT Image 2 (High) produces noticeably more polished images. The trade-off: GPT Image 2 is slower and doesn't preserve identity as well.
Learn more →Use Seedream 4.5 for photoreal portraits
For portraits where you want maximum photorealism and you're not doing instruction edits, Seedream 4.5 produces more lifelike skin tones and lighting. Nano Banana 2 is stronger when the task is 'edit this specific photo'.

Nano Banana 2 tips: prompts for precise, identity-safe edits
Three habits that consistently produce better Nano Banana 2 results, based on testing instruction-style edits across many subjects.
1. Write commands, and name what to keep
Nano Banana 2 follows instructions, not descriptions: 'change the denim jacket to a pink dress' beats 'a woman in a pink dress'. Lead with action verbs — change, replace, add, remove, make — and spell out what should stay untouched: 'keep the face and background identical'. Naming the parts you don't want changed helps the model focus on the targeted edit.
2. One change per prompt, then iterate
'Change the jacket AND the hair AND the background' often produces mixed results. Make one edit, save the result, then run the next edit on the saved version. Iterative editing beats batching every change into a single prompt.
3. Match resolution and ratio to where it'll be used
1K is the default and fine for most cases; use 2K for print and banner work, 4K for high-DPI displays — don't pay for resolution you don't need. Need both a 1:1 social post and a 9:16 story? Generate one, then re-run the same prompt at the other ratio; identity preservation keeps the subject coherent across both.
