Published: 2026-8-24 10:51 Publisher: 灵犀一指 View: Comments: 0

 With so many AI image-generation models available today, choosing the right one for architectural design can be challenging. Banana Pro and GPTimage2 are both well-known options, but how does Lingxi, SUAPP AI's in-house model, compare?

So we cut the fluff. We ran all three models side by side in SUAPP AI's Inspiration Render, using the exact same test criteria. All three models were evaluated under the same test conditions, using the same prompts and base images.
The results? See for yourself at the end – then pick what works best for you.

The Models We Tested
Lingxi – built in‑house by SUAPP AIBanana Pro – third‑party APIGPTimage2 – third‑party API
Inside SUAPP Inspiration Render, you can access all three models in two ways:
● Via "Editing" – toggle the button and pick your model.
● Via "Style" – choose by the style badge on each preset.


What We Tested
All tests were run under identical conditions – same prompts, same base images, the whole deal. No shortcuts, Each model was evaluated using the same prompts, source images, and criteria. We ran them across multiple cases to evaluate these key dimensions:

Final Verdict 
Based on the 10 test cases above, here’s our overall takeaway.
A few quick caveats first: This comparison is intended as a practical reference rather than a definitive benchmark. The results are based on the specific prompts, source images, and test conditions used in this evaluation, so performance may vary across different workflows and use cases. With only 10 samples, results can vary – different prompts, different base images, or even differences in model behavior from one generation to another. can shift the outcome. So take this as a helpful guide, not gospel.

Lingxi – The Fidelity Leader
Across the 10 test cases, Lingxi ranked first or tied for first in prompt fidelity in 8 cases. Whether it's a detailed model or a simple massing, interior or bird's‑eye, close‑up or wide shot – building form, proportions, and perspective stay true to the original.
If your base image is already solid and you don't want the AI to significantly alter the original design – you just want polishing, re‑rendering, or a mood boost – pick Lingxi.
Best for:
● Polishing high‑detail renders (structure locked, quality only)
● Photo‑realistic image enhancement (lighting + atmosphere)
● Atmosphere upgrades that preserve architectural proportions
● Fast iteration (approximately 20 seconds per generation)

Banana Pro – The Visual Powerhouse
Banana Pro ranked first or tied for first in creativity in 7 of the 10 test cases, and tied with Lingxi on realism and atmosphere more often than not. Punchy visuals, fresh design language, crisp material textures – well‑rounded with no major weak spots.
One notable exception was the extra-large coastal town scene in Case 8, where Banana Pro ranked behind the other two models across all five evaluated dimensions. Once the scene hits a town‑scale, it starts to struggle.
For everyday rendering needs, Banana Pro is a solid all‑rounder. Go for it when you want eye‑candy and creative flair – just don't push it to city‑scale.
Best for:
● Everyday rendering (small to large scenes)
● Facade design explorations that need creative sparks
● High‑impact presentation visuals
● Interiors and material‑rich renderings

GPTimage2 – Strongest for Large-Scale Scenes & Text
GPTimage2 has two killer moves: extra‑large scenes and text rendering.
In Case 8 (extra‑large bird's‑eye), GPTimage2 swept the board – creativity, realism, atmosphere, and material texture all ranked first. In Case 10 (cover design), it took top spot for both creativity and text rendering.
One possible explanation is GPTimage2's ability to handle complex spatial relationships, detailed instructions, and text-heavy compositions. In our tests, it performed particularly well when the image required complex spatial organization or accurate text placement.
For sprawling views, text‑heavy layouts, infographics, and analytical diagrams – let GPTimage2 handle the thinking.
Best for:
● Extra‑large bird's‑eye views (town‑level or regional planning)
● Cover designs, analytical diagrams, and 2D presentations
● Outputs requiring text layout and information display
● Polishing fine‑detail renders
● Complex scenes that demand logical coherence
