Common questions
Which AI is best for interior design?
Suede 2.5 (by Room AI) leads the Q2 2026 Interior Design Benchmark with an ELO of 1147 and a composite score of 8.78 / 10, ranking ahead of Midjourney v6.1 (8.45) and Flux.1 Pro (8.33). Suede 2.5 was the highest-scoring model on style fidelity (9.1), spatial coherence (8.9), and consistency (8.7) across the 60-prompt evaluation set covering 10 room types and 6 design styles.
How does Room AI compare to Midjourney?
On the Q2 2026 Interior Design Benchmark, Room AI's latest advanced model Suede 2.5 ranks #1 with an ELO of 1147 and Midjourney v6.1 ranks #2 with an ELO of 1119. Suede 2.5 generates images in an average of 4.8 seconds vs. Midjourney's 12.4 seconds, while scoring higher on style fidelity (9.1 vs 8.7) and spatial coherence (8.9 vs 8.5). Midjourney remains a strong general-purpose generator; Suede 2.5 is purpose-tuned for interior visualisation.
What's the fastest AI for room design?
Linen 1.0, Room AI's legacy fast model, has the fastest average generation time on the Q2 2026 benchmark at 2.9 seconds — faster than Ochre (4.3s), Suede 2.5 (4.8s), Imagen 3 (5.4s), Adobe Firefly 3 (5.8s), and Midjourney v6.1 (12.4s). Linen 1.0 trades some fidelity for speed and is best when you need quick iteration across mainstream room types and styles.
How was the benchmark conducted?
The Room AI Interior Design Benchmark uses a 60-prompt dataset spanning 10 room types and 6 design styles. Each model is scored across 5 dimensions — style fidelity, spatial coherence, style consistency, edge case handling, and generation time — with ELO ratings derived from 1,200+ pairwise blind comparisons by interior design professionals. The full methodology is published at /benchmarks/methodology.
Which Room AI model should I use?
Use Suede 2.5 when you want flagship quality for client-ready or final renders — it's the latest advanced model and the highest-scoring on every interior dimension. Use Linen 1.0 (legacy fast model) when you want speed for quick exploration of multiple ideas; it generates in 2.9 seconds. Use Ochre when you need standalone images, mood boards, or decor concepts that don't require a full room layout.
What's the difference between Linen 1.0 and Suede 2.5?
Linen 1.0 is the original Linen release — Room AI's legacy fast model, kept available for users who prefer its 2.9-second generation time. Suede 2.5 is the latest advanced model, released as a separate flagship line; it ranks #1 on the Q2 2026 benchmark with composite 8.78 / 10 and is purpose-tuned for high-fidelity, precise redesigns.
Is the benchmark dataset available?
The 60-prompt benchmark dataset is available on request for academic and partner use. Reach out via the contact form on the methodology page and reference the Q2 2026 dataset version. We update the benchmark each quarter as new models are released.
