This powerful AI integration allows you to generate custom visuals directly in your workflows, enabling creative content generation, visual prototyping, and automated image creation based on textual descriptions.
Key Features
- • AI-Powered Generation: Uses Together AI for high-quality image creation
- • Text-to-Image: Converts descriptive prompts into visual content
- • Creative Flexibility: Generate any type of image from text descriptions
- • URL Output: Returns generated images as accessible URLs
- • Workflow Integration: Seamlessly fits into automated creative processes
- • Prompt-Based Control: Full control over image generation through text input
Prerequisites
AI Service Access
Must have access to Together AI image generation service
Creative Requirements
Technical Requirements
Node Configuration
Required Fields
Prompt
The text prompt describing the image you want to generate. Be specific and detailed about the subject, style, composition, colors, and any other visual elements you want to see in the generated image.
Technical Details
Image Generation Process
How the node processes inputs and generates images using Together AI
Input Processing
The node processes the text prompt input:
- • Prompt Parsing: Extracts and validates the text prompt input
- • Template Processing: Resolves any template variables in the prompt
- • Input Validation: Ensures the prompt is provided and valid
AI Service Integration
Creates a new TogetherAI instance and calls the createImagemethod with the processed prompt. The service handles the actual AI model interaction and image generation process.
Response Handling
How the node processes the AI service response and formats outputs
Image URL Extraction
The node extracts the URL from the first generated image in the response array. Currently accesses (images[0] as any).url to get the image URL from the Together AI response structure.
Output Formatting
Returns the image URL in the standard output format with the field keyIMAGE and the URL as the value. The output is structured as an array of strings for consistency with the field definition.
Error Handling
How the node handles potential failures and errors
API Failures
If the Together AI service fails or returns an error, the node will throw an exception. This includes network failures, authentication errors, rate limiting, or service unavailability.
Response Validation
The node assumes the response contains an array with at least one image object that has a URL property. If the response structure is unexpected, this could cause runtime errors.
Examples & Use Cases
Simple Object Generation
Generate a basic image of a specific object
{
"prompt": "A red apple on a white background, photorealistic style"
}This will generate a photorealistic image of a red apple placed on a clean white background, perfect for product photography or educational content.
Artistic Style Generation
Create images in specific artistic styles
{
"prompt": "A futuristic city skyline at sunset, painted in the style of Van Gogh with swirling clouds and vibrant colors"
}This will generate an artistic interpretation of a futuristic cityscape using Van Gogh's distinctive painting style with swirling brushstrokes and vibrant color palette.
Character Design
Generate character illustrations and designs
{
"prompt": "A friendly robot character with round blue eyes, silver metallic body, cartoon style, holding a flower"
}This will create a cute, cartoon-style robot character with the specified features, perfect for game design, storytelling, or branding purposes.
Landscape Generation
Create natural and fantasy landscapes
{
"prompt": "A mystical forest with glowing mushrooms, ancient trees, and soft mist, fantasy art style, magical atmosphere"
}This will generate a fantasy landscape with magical elements, perfect for book covers, game backgrounds, or creative inspiration.

Best Practices
Do's
- • Be specific and detailed in your image descriptions
- • Include style, composition, and mood in your prompts
- • Use descriptive adjectives for colors, lighting, and atmosphere
- • Specify artistic styles when you want particular aesthetics
- • Test different prompt variations to find what works best
- • Consider the intended use case when writing prompts
- • Use template variables for dynamic content generation
Don'ts
- • Don't use overly vague or ambiguous descriptions
- • Avoid conflicting style instructions in the same prompt
- • Don't expect exact replication of copyrighted characters
- • Avoid overly complex prompts that may confuse the AI
- • Don't forget to specify important visual elements
- • Avoid using technical jargon the AI may not understand
- • Don't assume the AI will understand cultural references
Troubleshooting
Common Issues
API Authentication Failures
Symptoms: Node fails with authentication or authorization errors
Solution: Verify your Together AI API key is valid and has the necessary permissions for image generation. Check if your account has sufficient credits and is not suspended.
Poor Image Quality
Symptoms: Generated images are low quality or don't match the prompt
Solution: Improve your prompt by being more specific about style, composition, lighting, and artistic direction. Use clear, descriptive language and avoid ambiguous terms.
Service Unavailable Errors
Symptoms: Node fails with service unavailable or timeout errors
Solution: Check your internet connection and Together AI service status. The service may be experiencing high load or maintenance. Try again later or check Together AI's status page.
Unexpected Output Format
Symptoms: Node returns errors or unexpected data structure
Solution: This may indicate changes in the Together AI API response format. Check the API documentation for updates or contact support if the issue persists.
