MiniMax Image-01

MiniMax Image-01 Image-to-Image

MiniMax Image-01 Image-to-Image is an advanced AI model that transforms existing images using text prompts. Part of the MiniMax image-01 family, this model enables you to generate variations, apply style transfers, modify compositions, and create character-consistent images from reference photos. Perfect for creative workflows, product visualization, and content creation.

Key Features

• Image-Based Generation Generate new images based on an existing image input combined with text prompts. The model intelligently understands the reference image and applies your text description to create variations.

• Character Reference Support Use portrait photos as character references to maintain consistent character appearance across generated images. Ideal for creating character variations, different poses, or placing characters in new scenes.

• Flexible Image Dimensions Specify custom dimensions from 512×512 to 2048×2048 pixels (must be divisible by 8) for precise control over output size. Common sizes include 1024×1024, 1280×720, 1152×864, and more.

• Prompt Optimization Built-in prompt optimizer automatically enhances your text descriptions for better generation results, helping you achieve the desired output even with simple prompts.

• Batch Generation Generate up to 9 images in a single request, perfect for exploring variations and selecting the best result.

• Reproducible Results Use seed values to generate consistent results across multiple runs, essential for iterative refinement and production workflows.

Use Cases

• Product Visualization: Transform product photos into different contexts, backgrounds, or styles
• Character Art: Create consistent character variations with different poses, outfits, or environments
• Style Transfer: Apply artistic styles or visual treatments to existing images
• Image Editing: Modify specific aspects of an image through natural language descriptions
• Creative Exploration: Generate multiple variations of a concept for selection and refinement
• Content Creation: Quickly produce social media content, marketing materials, or creative assets

How to Use

Basic Image-to-Image Generation

1. Upload Reference Image

   • Provide a public URL or Base64-encoded image in the image field
   • Ensure the image is in JPG, JPEG, or PNG format and under 10MB

2. Write Your Prompt

   • Describe the desired output in the prompt field (max 1500 characters)
   • Example: "Transform this photo into a watercolor painting style with soft pastel colors"

3. Select Image Size

   • Specify dimensions using the size parameter like "10241024" or "1280720"
   • Choose dimensions that match your use case (square for social media, widescreen for presentations, etc.)

4. Configure Options

   • num_images: Set 1-9 to generate multiple variations
   • prompt_optimizer: Enable for automatic prompt enhancement
   • seed: Use for reproducible results

5. Generate

   • Submit your request and receive generated images as URLs or Base64 strings

Character Reference Generation

For consistent character appearance:

1. Prepare Portrait Photo

   • Use a clear, front-facing portrait with good lighting
   • Single person in frame works best

2. Configure Character Reference

   • Use the subject_reference parameter with type "character"
   • Provide the portrait image URL or Base64 data

3. Describe the Scene

   • Write a prompt describing the desired scene, pose, or context
   • Example: "The character standing on a mountain peak at sunset"

API Parameters

• prompt (required): Text description of desired output (max 1500 chars)
• image (required): Reference image as URL or Base64 string
• size: Image dimensions (e.g., "1024 * 1024", "1280 * 720")
• num_images: Number of images to generate (1-9, default: 1)
• seed: Random seed for reproducible results
• prompt_optimizer: Enable automatic prompt enhancement (boolean)
• enable_base64_output: Return Base64 instead of URLs (boolean)
• enable_sync_mode: Wait for generation to complete before returning (boolean)
• subject_reference: Array of character reference images (optional)

Pricing

• $0.0035 per image
• Generate multiple images in one request for efficient batch processing
• Total cost = $0.0035 × number of images generated

Output Format

Generations return as:

• URLs (default): Direct links to generated images hosted on WaveSpeedAI
• Base64 (optional): Encoded image data for direct embedding

Response includes:

• Unique request ID for tracking
• Generation status (created, processing, completed, failed)
• Output array with generated image URLs or Base64 data
• NSFW content detection flags
• Creation timestamp

Best Practices

• Use clear, well-lit reference images for best results
• For character references, front-facing portraits work best
• Enable prompt optimizer if you're new to prompt writing
• Use seed values when iterating on a specific result
• Generate multiple variations (num_images > 1) to select the best output
• Keep prompts descriptive but concise for optimal results
