Nano Banana 2 Specs
What makes Nano Banana 2 different 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.
Best-in-class 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.
15 aspect ratios, including extremes
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 expose the 7 most useful 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 Excels At
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. The Lineup
When to use Nano Banana 2 — and when one of the other three is a better choice.
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'.

Getting the Most Out of Nano Banana 2
Five habits that consistently produce better Nano Banana 2 results — based on testing instruction-style edits across many subjects.
1. Write instructions, not descriptions
'Change the denim jacket to a pink dress' beats 'a woman in a pink dress'. Nano Banana 2 was trained to follow commands — leverage that. Use action verbs like 'change', 'replace', 'add', 'remove', 'make'.
2. Be explicit about what to preserve
If you want the rest of the image untouched, say so: 'change just the jacket, keep the face and background identical'. This is redundant but helps the model focus on the targeted change.
3. One change per prompt
'Change the jacket AND the hair AND the background' often produces mixed results. Make one edit, save the result, then do the next edit on the saved version. Iterative editing produces better outcomes than batched.
4. Pick resolution to match output use
1K is the default and works for most cases. Use 2K for print/banner work, 4K when you're producing assets for high-DPI displays or print without external upscaling. Higher resolutions cost more credits — don't pay for resolution you don't need.
5. Try aspect ratio variants for the same subject
Need a 1:1 social post AND a 9:16 story version? Generate the 1:1 first, then re-generate with the same prompt at 9:16. Identity preservation usually keeps the subject coherent across aspect ratios.
