Professional digital artists face complex decisions when selecting AI models for their workflow

Architectural Foundations and Training Approaches

Seedream 4.5 operates on a transformer-based architecture with specialized attention mechanisms for spatial relationships. The model was trained on a curated dataset emphasizing architectural accuracy, geometric precision, and material representation. This training approach results in exceptional performance for technical illustrations, product visualization, and scenes requiring exact spatial relationships. The model demonstrates particular strength in:

• Geometric Consistency: Buildings, vehicles, and manufactured objects maintain proper proportions
• Material Accuracy: Differentiates between metal, glass, wood, fabric with realistic textures
• Spatial Awareness: Maintains consistent perspective and depth relationships

GPT Image 1.5 utilizes a diffusion-based approach combined with reinforcement learning from human feedback. The training data prioritizes artistic interpretation, emotional expression, and stylistic coherence. This foundation makes the model excel at:

• Stylistic Adaptation: Can mimic specific artistic movements or painterly techniques
• Emotional Expression: Conveys mood through color, composition, and lighting
• Narrative Cohesion: Maintains thematic consistency across complex scenes

💡 Key Insight: Seedream 4.5 treats image generation as an engineering problem—optimizing for accuracy and fidelity. GPT Image 1.5 approaches it as an artistic problem—prioritizing expression and interpretation.

Photorealistic Quality and Detail Resolution

The fundamental difference in approach: mathematical precision versus organic interpretation

Seedream 4.5 delivers exceptional detail resolution in technical domains. When generating architectural visualizations, the model produces:

• Crisp Edge Definition: Clean lines without artifacting or blurring
• Material Texture Accuracy: Realistic surface properties based on physical materials
• Consistent Lighting: Physically plausible illumination with proper shadows
• Scale Preservation: Objects maintain proper relative sizes throughout compositions

Performance Benchmarks for Technical Scenes:

GPT Image 1.5 excels in organic and natural scenes. For portraits, landscapes, and atmospheric compositions:

• Naturalistic Color Grading: Subtle, harmonious color relationships
• Organic Form Representation: Natural curves and flowing shapes
• Atmospheric Effects: Mist, fog, light diffusion with realistic scattering
• Emotional Color Palettes: Color choices that reinforce mood and theme

Artistic Style Interpretation and Adaptation

Neural network precision meets intuitive brushwork—different paths to creative expression

Seedream 4.5 interprets artistic styles through a technical lens. When instructed to generate "impressionist painting," the model:

• Maintains Structural Integrity: Buildings and objects retain proper form
• Applies Style as Surface Treatment: Brushstrokes overlay accurate underlying structures
• Preserves Spatial Relationships: Depth and perspective remain consistent
• Optimizes for Recognizability: Subjects remain clearly identifiable

GPT Image 1.5 approaches style as fundamental transformation. The same "impressionist painting" prompt yields:

• Form Adapts to Style: Objects may distort or soften to match artistic movement
• Style Informs Composition: Arrangement follows artistic conventions of the style
• Emphasis on Emotional Impact: Prioritizes mood over technical accuracy
• Coherent Stylistic Language: All elements follow consistent artistic rules

GPT Image 1.5 excels with artistic and emotional descriptions:

• Mood and Emotion: Understands "melancholic," "joyful," "tense atmospheric"
• Artistic References: Interprets "in the style of Turner's seascapes"
• Color Psychology: Responds to "warm autumn palette with golden undertones"
• Narrative Elements: Incorporates "storytelling through composition"

Effective Prompt Structure for GPT Image 1.5:

[Emotional/Mood Context] + [Artistic Style Reference] + [Color Palette] + [Composition Intent] + [Atmospheric Elements]
Example: "Melancholic portrait in the style of Rembrandt's chiaroscuro, warm golden light illuminating subject's face against dark background, intimate close-up capturing emotional depth"
