Top AI Models for Interior Design in 2025
With the explosion of AI tools for interior design, it can be challenging to determine which one delivers the best results. We've tested and compared the leading AI models to help you make an informed decision for your next room redesign project.
General-Purpose AI Image Generators
Midjourney
Strengths: Midjourney excels at creating aesthetically pleasing interior designs with impressive lighting effects and textures. Its outputs are often artistic and visually striking.
Weaknesses: Limited control over room layout preservation, which can result in structural impossibilities. Designs often prioritize aesthetics over practicality, and there's no shopping list integration.
Best for: Inspiration and mood board creation rather than practical redesigns.
DALL-E 3
Strengths: DALL-E 3 produces clean, coherent interior designs with reasonable spatial awareness. It handles text instructions well and generates diverse style options.
Weaknesses: Struggles with preserving exact room dimensions and sometimes produces unrealistic furniture arrangements. No shopping recommendations or practical implementation guidance.
Best for: Quick visualization of different interior styles.
Stable Diffusion
Strengths: Highly customizable with various fine-tuned models specifically for interiors. Open-source nature allows for community improvements and specialized applications.
Weaknesses: Requires technical knowledge to achieve optimal results. Quality varies widely depending on the specific model and parameters used. No built-in furniture recommendations.
Best for: Technical users who want to customize the AI generation process.
Specialized AI Interior Design Tools
ControlNet-Based Solutions
Strengths: Maintains structural integrity of rooms by preserving layouts while changing styles. Better spatial awareness than general AI models.
Weaknesses: Often requires multiple steps and technical knowledge to implement properly. Results can look artificial without proper tuning.
Best for: Users who want to maintain exact room proportions and layouts.
Interior-Specific Diffusion Models
Strengths: Trained specifically on interior design data, these models better understand design principles, furniture placement, and style cohesion.
Weaknesses: Less accessible to average users and often require subscription to specialized platforms.
Best for: Professional designers looking for AI assistance with realistic room transformations.
What Makes the Best AI for Interior Design?
After extensive testing, we've identified these key factors that separate the best AI interior design tools from the rest:
1. Spatial Awareness
Top-tier AI must understand room dimensions, preserve architectural features, and place furniture in physically possible arrangements.
2. Style Consistency
The AI should maintain a cohesive design language across all elements in the room, from furniture to decor.
3. Practical Implementation
Beyond just pretty pictures, the best tools provide shopping recommendations, furniture specifications, and implementation guidance.
4. User-Friendly Interface
Technical AI capabilities must be wrapped in an accessible interface that doesn't require prompt engineering expertise.
5. Speed and Cost
Professional-quality results should be delivered quickly and at a reasonable price point compared to traditional interior design services.
Our Solution: Combining the Best AI Technologies
At InstantInterior AI, we've built our platform using a proprietary combination of specialized interior design AI models, enhanced with ControlNet for layout preservation and custom-trained on thousands of professional interior designs.
Unlike general-purpose AI image generators that produce pretty but impractical designs, our system:
- Preserves original room architecture and dimensions
- Generates designs that can be implemented in the real world
- Provides curated shopping lists for furniture and decor
- Delivers results in minutes rather than days
- Costs a fraction of traditional interior design services
