How It Works

This node transforms text descriptions into images using advanced AI image generation models. When you provide a detailed prompt describing what you want to create, the AI model interprets your description and generates a corresponding image. The negative prompt helps refine results by specifying unwanted elements, allowing for more precise control over the output. You can choose from different providers (Runware, DALL-E, Stable Diffusion), each with unique characteristics and strengths. Advanced users can specify particular models and apply LoRA modifications for style customization when using Runware.

Usage Examples

Example 1: Product Photography

Input:

provider: "Runware"
prompt: "Professional product photo of a sleek wireless headphone in matte black, floating on white background, studio lighting, high resolution, commercial photography, detailed texture"
negative_prompt: "blurry, low quality, distorted, cluttered background, watermark, text"
aspect_ratio: "1:1_FHD"

Output:

image: "https://storage.pixelml.com/images/headphones-product-abc123.png"

Example 2: Landscape Artwork

Input:

provider: "Stable Diffusion"
prompt: "Breathtaking mountain landscape at golden hour, snow-capped peaks, alpine lake reflection, dramatic clouds, vibrant sunset colors, photorealistic, 8k quality, nature photography"
negative_prompt: "people, buildings, cars, urban, artificial, cartoonish, oversaturated"
aspect_ratio: "16:9_HD"

Output:

image: "https://storage.pixelml.com/images/mountain-sunset-def456.png"

Example 3: Character Illustration

Input:

provider: "Dall-e"
prompt: "Fantasy character portrait, elegant elven warrior with silver armor, flowing purple cape, magical aura, detailed face, digital art, concept art style, dramatic lighting"
negative_prompt: "realistic, photograph, blurry, deformed, low quality, text, watermark"
aspect_ratio: "3:4_HD"

Output:

Error Handling

Error Type	Cause	Solution
Empty Prompt	Prompt parameter is missing or empty	Provide a detailed description of what you want to generate
Invalid Provider	Selected provider is not available or misspelled	Choose from valid providers: Runware, Dall-e, or Stable Diffusion
Content Policy Violation	Prompt contains prohibited content or keywords	Review and revise prompt to comply with content policies
Generation Timeout	Image generation taking longer than expected	Simplify the prompt or try again after a few minutes
Invalid Aspect Ratio	Aspect ratio not supported by selected provider	Choose a supported aspect ratio from the available options
Model ID Error	Specified model_id doesn't exist (Runware)	Verify the model ID is correct or leave blank for default
API Connection Failed	Cannot connect to PixelML API	Check your PixelML connection credentials and network status

Notes

• Provider Selection: Runware offers fast generation with model flexibility, DALL-E excels at following complex prompts, Stable Diffusion provides artistic control

• Prompt Engineering: Be specific about style, lighting, colors, composition, and details. More descriptive prompts yield better results

• Negative Prompts: Use negative prompts to avoid common unwanted elements like blur, distortion, watermarks, and low quality

• Aspect Ratios: Choose aspect ratios based on use case (1:1 for social media, 16:9 for presentations, 3:4 for portraits)

• Quality Settings: HD and FHD suffixes indicate higher resolution. FHD takes longer but produces superior quality for professional use

• LoRA Models: Advanced Runware feature that applies specific artistic styles or modifications to the base model

• Iteration: Image generation is often iterative. Try different prompts, negative prompts, and settings to achieve desired results

• Cost Consideration: Higher resolution (FHD) images consume more credits. Balance quality needs with budget constraints
