Best Practices for Text Generation

To achieve optimal text rendering results:

Be Specific: Clearly specify the exact text you want rendered
- Example: "A blue sign with white text saying 'OPEN 24 HOURS'"
Context Matters: Describe where and how the text should appear
- Example: "A vintage coffee shop storefront with a wooden sign reading 'The Daily Grind' in elegant script"
Style Guidance: Specify font characteristics
- Example: "A minimalist poster with bold sans-serif text 'INNOVATION' in black on white background"
Use Quotes: Enclose desired text in quotes within your prompt
- Example: "Create a motivational poster with the text 'Dream Big' in gold letters"

Limitations and Workarounds

While impressive, text rendering has some limitations:

Very long paragraphs may have inconsistencies
Extremely complex layouts might require multiple iterations

Best Practices and Prompting Tips

Maximize your results with Seedream 4.5 by following these proven techniques:

Effective Prompt Structure

The Formula: [Subject] + [Action/Pose] + [Environment/Setting] + [Style] + [Technical Details] + [Text Content]

Example:

A professional businessman (subject) presenting at a conference (action) in a modern auditorium (environment), photorealistic style (style), with a slide behind him showing the text 'Q4 RESULTS' (text content), cinematic lighting, sharp focus (technical)

Prompting Best Practices

1. Be Specific and Descriptive

Vague: “A nice poster”
Better: “A minimalist movie poster with bold typography, dark blue background, dramatic lighting”

2. Use Style Keywords

Photography: “cinematic”, “portrait”, “bokeh”, “golden hour”, “studio lighting”
Art: “oil painting”, “watercolor”, “digital art”, “impressionist”, “art nouveau”
Design: “minimalist”, “flat design”, “isometric”, “material design”, “retro”

3. Specify Text Clearly

Always use quotes around desired text
Specify font characteristics: “bold”, “serif”, “handwritten”, “elegant”
Describe text placement: “centered”, “top of image”, “on a sign”, “as a logo”

4. Control Composition

Specify viewpoint: “aerial view”, “close-up”, “wide shot”, “eye-level”
Define framing: “centered composition”, “rule of thirds”, “symmetrical”
Set focus: “shallow depth of field”, “everything in focus”, “blurred background”

5. Manage Color and Mood

Color palettes: “vibrant colors”, “muted tones”, “monochromatic”, “pastel”
Lighting: “soft lighting”, “dramatic shadows”, “backlit”, “neon glow”
Atmosphere: “moody”, “cheerful”, “mysterious”, “energetic”

Common Mistakes to Avoid

1. Overcomplicating Prompts

Don’t: “A photo of a cat sitting on a chair in a room with blue walls and a window showing a sunny day with clouds and a tree outside and there’s also a lamp and a book…”
Do: “A tabby cat sitting on a vintage armchair in a cozy room, soft natural window light, minimalist interior”

2. Conflicting Instructions

Don’t: “Photorealistic cartoon character” (contradictory)
Do: “3D rendered character with realistic textures” or “Stylized illustration with detailed shading”

3. Neglecting Negative Prompts

Use negative prompts to exclude unwanted elements
Example: negative_prompt: "blurry, low quality, distorted, watermark, signature"

4. Ignoring Aspect Ratio for Use Case

Match dimensions to your needs
Social posts: Square (1024x1024)
Stories/Reels: Portrait (1024x1536)
Headers/Banners: Landscape (2048x1024)

Advanced Techniques

Seed-Based Iteration

# Generate variations of a successful image
base_prompt = "A modern tech startup office, collaborative workspace"
seed = 42  # Use seed from successful generation

# Create variations by slightly modifying prompt
variations = [
    f"{base_prompt}, morning light",
    f"{base_prompt}, evening atmosphere",
    f"{base_prompt}, minimalist design"
]

for variation in variations:
    generate_image(variation, seed=seed)

Layered Prompt Building

# Build complex prompts progressively
subject = "A vintage bookshop"
environment = "with floor-to-ceiling wooden shelves"
atmosphere = "warm ambient lighting, cozy atmosphere"
details = "a sign reading 'RARE BOOKS' above the entrance"
style = "photorealistic, architectural photography style"

full_prompt = f"{subject} {environment}, {atmosphere}, {details}, {style}"

Style Consistency Across Series

# Define consistent style base
style_base = "minimalist digital illustration, flat colors, geometric shapes, modern design"

# Apply to different subjects
subjects = [
    "a coffee cup",
    "a laptop",
    "a desk plant"
]

for subject in subjects:
    prompt = f"{subject}, {style_base}"
    generate_image(prompt)

Quality Optimization Checklist

Before generating, verify:

Prompt clearly describes the subject
Style and mood are specified
Resolution matches intended use
Text content is in quotes and clearly specified
Technical details (lighting, composition) are included
Negative prompt excludes unwanted elements
Aspect ratio is appropriate for use case

A: Seedream 4.5 supports up to 2048x2048 pixels, providing 4K-quality output suitable for professional use.

Q: How long does image generation take?

A: Generation typically takes 5-15 seconds depending on resolution and complexity. Higher resolutions and quality settings may take longer.

Q: Can I use custom aspect ratios?

A: The model supports predefined aspect ratios including square, portrait, and landscape orientations. Custom ratios must be selected from available size options.

Text Rendering Questions

Q: Can Seedream 4.5 render text in any language?

A: Seedream 4.5 performs best with English text but can handle other Latin-script languages. Non-Latin scripts (Chinese, Japanese, Arabic, etc.) may have varying results depending on complexity.

Q: Why doesn’t my text appear exactly as specified?

A: AI image generation is probabilistic. For best results:

Use quotes around exact text
Be specific about font style and placement
Generate multiple versions and select the best
Keep text concise and clear

Q: Can I control font style?
