Key Parameters

Best Practices

1. Write Detailed Design Prompts

✗ Bad: "modern room"
✓ Good: "Modern minimalist living room with Scandinavian furniture, white walls, oak floor, large windows, indoor plants"

Include: Style, furniture, colors, lighting, materials, atmosphere

2. Use Appropriate Strength Values

# Subtle changes
strength = 0.5

# Moderate redesign
strength = 0.7

# Complete transformation
strength = 0.9

3. Quality vs Speed

# Fast (21 steps)
num_inference_steps = 21

# Balanced (31 steps) - Recommended
num_inference_steps = 31

# Best quality (41 steps)
num_inference_steps = 41

4. Use High-Quality Input Images

• Well-lit room photos
• Clear view of the space
• Minimal distortion
• High resolution preferred

Common Use Cases

Virtual Staging

def stage_empty_room(room_image, style, api_key):
    """Stage an empty room for real estate listing."""
    return decorate_room(
        room_image,
        f"{style} furnished room with modern furniture, well-lit, professional",
        api_key
    )

# Stage for listing
staged = stage_empty_room(
    "https://example.com/empty-apartment.jpg",
    "Modern luxury",
    api_key
)

Design Variations

def create_design_variations(room_image, styles, api_key):
    """Generate multiple design style variations."""
    variations = []

    for style in styles:
        variant = redesign_interior(
            room_image,
            f"{style} interior design style",
            api_key
        )
        variations.append(variant)
        print(f"{style}: {variant}")

    return variations

# Generate variations
designs = create_design_variations(
    "https://example.com/room.jpg",
    ["Modern Scandinavian", "Industrial Loft", "Classic Traditional", "Bohemian"],
    api_key
)

Renovation Planning

def plan_renovation(current_room, desired_style, api_key):
    """Plan room renovation with before/after."""
    before = current_room

    after = redesign_interior(
        before,
        f"Renovated {desired_style} room with updated fixtures and furniture",
        api_key
    )

    return {"before": before, "after": after}

# Plan kitchen renovation
plan = plan_renovation(
    "https://example.com/old-kitchen.jpg",
    "modern farmhouse kitchen",
    api_key
)

Complete Room Makeover

def complete_room_makeover(room_image, api_key):
    """Full room transformation workflow."""

    # Step 1: Remove unwanted items
    cleaned = remove_interior_object(
        room_image,
        "old furniture and clutter",
        api_key
    )

    # Step 2: Redesign space
    redesigned = redesign_interior(
        cleaned,
        "Modern minimalist interior with natural materials",
        api_key
    )

    # Step 3: Add specific decor
    final = decorate_room(
        redesigned,
        "Add cozy lighting and indoor plants",
        api_key,
        specific_object="pendant lamp"
    )

    return final

Before/After Scenarios

# Day to night transformation
day_room = "https://example.com/daytime.jpg"

night = change_room_scenario(
    day_room,
    "Evening ambiance with warm lighting, twilight outside windows",
    api_key
)

# Summer to winter
winter = change_room_scenario(
    day_room,
    "Winter scene with snow outside, cozy fireplace, warm interior",
    api_key
)

Error Handling

try:
    design = redesign_interior(room_image, prompt, api_key)
    print(f"Design created: {design}")
except Exception as e:
    print(f"Design generation failed: {e}")
    # Log error, try different prompt, notify user

Performance Tips

1. Use Appropriate Inference Steps: 31 steps balances quality and speed
2. Optimize Prompts: Clear, detailed prompts work best
3. Batch Similar Requests: Generate multiple variations together
4. Cache Results: Store generated designs
5. Monitor Quality: Adjust strength and guidance_scale as needed
