How to Use Stable Diffusion 3.5 Medium
Getting Started with SD 3.5 Medium
- Choose Your Platform: Select from cloud-based services like Replicate, Vast AI, or install locally using ComfyUI or Automatic1111 interfaces. Cloud platforms require no setup, while local installation offers more control and privacy.
- Prepare Your Prompt: Write a detailed text description of the image you want to create. Be specific about subjects, style, lighting, composition, and artistic elements. SD 3.5 Medium excels at understanding complex, detailed prompts.
- Configure Generation Parameters: Set your desired resolution (the model supports multiple aspect ratios), number of inference steps (typically 20-50), and guidance scale (controls how closely the output follows your prompt).
- Generate and Refine: Execute the generation process and review results. Use the model’s strong customization capabilities to fine-tune outputs through iterative prompting or parameter adjustments.
- Apply Advanced Techniques: Leverage features like ControlNet for precise composition control, LoRA models for style customization, or img2img workflows for image-to-image transformations.
Best Practices for Optimal Results
- Use descriptive, structured prompts with clear subject-verb-object relationships
- Specify artistic style, medium, and technical details (e.g., “oil painting,” “cinematic lighting,” “8K resolution”)
- Experiment with different sampling methods and step counts to balance quality and generation speed
- Take advantage of the model’s superior typography capabilities by clearly specifying text elements in your prompts
- Utilize negative prompts to exclude unwanted elements from generated images
