# Super Arbor AI Interior Design Benchmark Tested September 30, 2026; published October 1, 2026. https://leaderboard.superarbor.com/ 51 requests across 17 endpoints and three scenes; 45 images; total measured usage $6.3678 USD. Two interiors determine the interior score; exterior is separate. ## Results | Model | Interior /100 | Exterior /100 | USD/image | Median seconds | Returned | |---|---:|---:|---:|---:|---:| | GPT Image 2.5 Sunburst | 89.8 | 87.8 | $0.2769 | 90.327 | 3/3 | | GPT Image 2.5 Flare | 88.5 | 88.2 | $0.2769 | 50.442 | 3/3 | | GPT Image 2 | 86.9 | 87.0 | $0.2768 | 105.056 | 3/3 | | Grok Imagine Image 2.0 | 86.5 | 85.5 | $0.0900 | 25.088 | 3/3 | | Grok Imagine Image Quality | 84.8 | 87.5 | $0.0800 | 17.038 | 3/3 | | Muse Image | 84.6 | 90.5 | $0.0100 | 17.223 | 3/3 | | Hunyuan Image 3.0 Instruct | 84.1 | 81.0 | $0.0900 | 54.247 | 3/3 | | Seedream 5.0 Pro | 82.6 | 86.2 | $0.1350 | 127.935 | 3/3 | | Nano Banana Pro | 81.9 | 92.5 | $0.1500 | 25.345 | 3/3 | | Seedream 5.0 Lite | 80.8 | 77.0 | $0.0350 | 52.784 | 3/3 | | Ideogram 4.5 | 79.1 | 83.0 | $0.2200 | 37.494 | 3/3 | | Grok Imagine Image | 78.0 | 84.2 | $0.0220 | 23.213 | 3/3 | | Qwen Image 3 Pro | 77.5 | 85.5 | $0.0780 | 150.813 | 3/3 | | Nano Banana 2 | 76.5 | 90.5 | $0.1220 | 31.485 | 3/3 | | GPT Image 1.5 | 75.9 | 82.0 | $0.2600 | 54.324 | 3/3 | | MAI Image 2.5 | Not ranked | Not ranked | — | — | 0/3 | | MAI Image 2.5 Pro | Not ranked | Not ranked | — | — | 0/3 | ## Interpretation Sunburst max led the pilot, with Flare max a practical quality tie and faster median. Grok 2.0 offered a quality/cost balance; Muse was lowest cost. Nano Banana Pro led the separate exterior case. ## Method and limitations One AI assistant scored structure/camera preservation (35%), design (25%), instruction adherence (25%), and realism (15%). Two interior scenes, one sample each. No independent blind review, crowd voting, Elo, or confidence intervals. Output sizes and quality settings differ. Small score differences are practical ties. This does not test exact catalog SKU reproduction or construction feasibility. Cost is response billable units times saved authenticated unit price; not invoice reconciliation. Timing includes queue and polling, excludes shared uploads and output download. Both MAI endpoints failed all three cases with zero reported billable units. Exterior prompt ambiguity: the door plaque was called a third glazed inset; exact door-pane count was not a scoring discriminator. ## Not tested in the connected fal catalog - MAI-Image-2.6 - MAI-Image-2.6-Flash - MAI-Image-2.5-Flash - HunyuanImage 3.5 Preview - Qwen-Image-2.1 - Luma UNI1 Max - HiDream-O1-Edit-15 ## Sources and full data https://leaderboard.superarbor.com/methodology/ https://leaderboard.superarbor.com/data/benchmark.json https://leaderboard.superarbor.com/data/leaderboard.csv ## Frozen prompts ### Conservatory restaurant Act as a senior interior designer creating a buildable, high-end renovation visualization of this exact photograph.
