GPT Image 2.5 vs Nano Banana 2: Which Fits Your Image Workflow?
Compare both models with the same prompts and reference images. Review a new image, a focused edit, and a two-reference outfit change. Then inspect the details that matter to your project.
Compare real workflows, prompts, and image results.

How This Comparison Was Run
Both models received the same creative brief and, where required, the same input files. Settings that could not be normalized across providers are stated instead of being treated as identical.
Test record
- Test date
- September 22, 2026
- Models tested
- GPT Image 2.5 Sunburst and Nano Banana 2 (Gemini 3.1 Flash Image)
- Prompt
- The complete prompt was copied unchanged between models for each test.
- Input images
- The editing and two-reference tests used the same source files in both models.
- Aspect ratio
- 1:1 for all three displayed comparisons.
- Output count
- One displayed result from each model for each task.
- Quality setting
- Provider-specific defaults were used; quality labels were not treated as equivalent across providers.
- Speed record
- Generation time was not recorded for these runs, so the page does not declare a speed winner.
Shared evaluation dimensions
- 01
Generation: Composition, prompt coverage, material detail, and overall usefulness
- 02
Editing: Whether the requested area changed without unrelated changes
- 03
Reference fidelity: Identity, product construction, clothing, and scene preservation
- 04
Text: Exact wording, punctuation, legibility, and placement
- 05
Speed: Observed generation time under matching provider conditions when recorded
The observations below describe the displayed runs. A different seed, provider setting, prompt, or input may produce a different result.

Cross-case observations
What the displayed runs show
Each observation refers to the images displayed above.
Generation
Both displayed outputs were usable; their difference was control versus reinterpretation.
Editing
In this watch run, Sunburst kept the edit closer to the requested boundary.
Reference fidelity
In this outfit run, Sunburst retained more information from both inputs.
Text
In this packaging run, Sunburst matched the requested wording more closely.
Speed
No speed winner is claimed because comparable timing data was not collected.
These observations describe the displayed runs rather than a universal model ranking.
GPT Image 2.5 vs Nano Banana 2: What to Compare
Product Photography and Material Detail
Inspect the texture of paper, fabric, metal, and glass. Check whether a product keeps its shape, labels, and recognizable details.
Text Rendering and Layout
Read every word in the output. An attractive layout is not enough if the wording changes or the text becomes unreadable.
Precise Image Editing
Look for unintended changes outside the requested region, especially faces, backgrounds, object placement, and lighting.
Two-Reference Consistency
The final composite should look like one photograph. The subject should remain recognizable, and the clothing should retain important details from the garment reference.
Speed and Cost
Record real generation times and the actual cost under your chosen provider. Do not assume equal quality labels, identical pricing units, or universal speed differences between platforms.
Best fit by workflow
Which Model Is Better for You?
There is no single winner for every image task. Choose based on the type of control, workflow, and provider features your project needs.
Choose GPT Image 2.5 Sunburst if...
- You need a focused edit with clear preservation rules.
- Product color, geometry, labels, or materials must stay controlled.
- A person or garment must remain close to multiple references.
Choose Nano Banana 2 if...
- You prefer a broader creative interpretation of the brief.
- Your workflow already runs inside supported Google products.
- Search-grounded image features are available and useful in your chosen Google product.
For a decision that affects repeated production work, rerun the same prompt and source files several times on the platforms you plan to use. Record speed, cost, failed constraints, and the amount of manual correction required.

GPT Image 2.5 vs Nano Banana 2 FAQ
Find quick answers about model capabilities, image workflows, and choosing the right option for your project.
Can both models edit existing images?
Yes. Both models support image-input workflows. Results depend on the source image, prompt, and settings.
Can I combine a person image and a clothing image?
Both model families support multiple image inputs. Use a clear role for each reference and describe which details to keep unchanged.
Is Nano Banana 2 available in this generator?
This page links to the GPT Image 2.5 generator. A Nano Banana 2 comparison output does not mean that this website offers Nano Banana 2 generation.
Is one model always more accurate?
No single example establishes a universal result. Inspect the outputs for the specific task, and repeat important tests when consistency matters.
Which GPT Image 2.5 model is shown here?
The test card should identify whether the output uses Flare or Sunburst. Visit the Flare vs Sunburst comparison for an explanation of these options.
