What are the best AI tools for interior design image generation in 2025?

The best AI tools for interior design image generation in 2025 are Seedream 5.0 Pro for precision room editing — changing wall colors from a palette and adding furniture from a menu — Nano Banana 2 Lite for high-volume concept exploration at 3 cents per image, and Nano Banana Pro for final client-ready renders. All three run inside invideo.

Match the tool to the design task rather than picking one model for everything. invideo is an agentic creation platform with all of these image models available, so you route each task to the right one instead of choosing a platform per model.

Seedream 5.0 Pro — edit and restyle an actual room. Use its precision editing to iterate on a real space: change wall colors via a color palette and populate the room with furniture from a pop-up menu, all in one interface without exporting between tools. Its multi-image fusion takes three or more source images — individual furniture pieces, props, and the room itself — and combines them into a single cohesive scene, which is how you preview a specific sofa in a specific living room. It also renders realistic materials and lighting, including directional shadow work and real-world lens characteristics like fisheye and split diopter, so outputs read as photographs rather than renders.

Nano Banana 2 Lite — explore concepts in volume. At 3 cents per image and roughly 4-second generation — 1,000 images for $30 — generate 20 to 50 style variants of a room instead of 3, then shortlist. It runs 2.5x faster than Nano Banana 2 at half the cost, and its 1K resolution is a deliberate trade-off for that speed, which is fine for mood boards and direction-finding. Per Google's own benchmarks, the cheapest model is no longer the worst model, so treat exploration as effectively free.

Nano Banana Pro — finalize the chosen concept. Escalate only the selected direction to Nano Banana Pro for the highest-quality output: client presentations, listing images, portfolio renders. The working principle is that only the chosen concepts get escalated — Lite for everything exploratory, Pro for the handful that ship. At 1,000-image volume, Lite runs four times cheaper than Pro, so this two-tier routing is where the economics come from.

Hold the design brief across the session. When you run dozens of variants, the bottleneck is not generation speed but losing track of what you told the model three images ago. Load the client's palette, style references, and room photos into the invideo agent once — its persistent memory carries that context across the whole session and routes each request to the right model, so generation 40 still matches the brief from generation 3.

Routing in short: restyling an existing room photo → Seedream 5.0 Pro precision editing; exploring styles and mood boards → Nano Banana 2 Lite; final presentation-grade images → Nano Banana Pro.

Watch some of these to see what works for you:

Realism, cinematic lighting, precise skin textures, lens understanding, precision editing, and multi-image fusion. All of it, natively inside invideo.
