Summary for GPT Image 1.5
GPT Image 1.5 demonstrates exceptional capability in text rendering, graphic design, and photorealistic architecture, securing the #2 spot on the leaderboard. It is a highly polished model that produces "safe," commercial-grade imagery with excellent resolution.
However, its performance is significantly bifurcated. While it scores consistently high (9.0+) in Graphic Design, it suffers from an aggressive safety filter that resulted in an 11% refusal rate overall. This is most notable in the Ghibli style category, where it refused 7 out of 10 prompts.
Key Takeaways:
- ✅ Top Tier: Unmatched in integrating text into images and creating clean vector-style graphics.
- ✅ High Fidelity: Excellent lighting and texture work in architectural and product photography.
- ☕️ Safety Constraints: The model is overly sensitive to copyright or style mimicry (e.g., "Studio Ghibli"), making it unreliable for specific artistic pastiches.
- ⚠️ Anatomy: Still struggles with complex hand interactions, mirroring the limitations of many current models.
General Analysis
GPT Image 1.5 exhibits a distinct personality: it is a precision instrument for commercial and typographic work but a rigid one for artistic mimicry.
🎨 Strengths: Precision and Polish
The model's greatest asset is its technical adherence to prompts involving structure and text.
- Text Rendering: It achieved an average of 8.6 in Text in Images. Examples like the Neon Sign and the Magical Book Cover show flawless spelling and integration of text into complex lighting environments.
- Visual Logic: The model excels at logical, structural prompts. The Cutaway architectural drawing scored a 9, demonstrating a deep understanding of spatial organization and labeling.
🚫 Weaknesses: The Safety Filter & Anatomy
- Aggressive Refusals: The model has the highest refusal rate among top contenders (11%). In the Ghibli style category, requests for specific styles (e.g., Kiki's Delivery Service style or Totoro style) were consistently rejected by the safety system. This severely limits its utility for fan art or specific style studies.
- Anatomical Struggles: In the Hands & Anatomy category, the model averaged a score of 6.44. It failed significantly on dynamic interactions, such as the High-fiving hands, where it hallucinated thumb anatomy, and the Yoga practitioner, which was refused entirely (likely due to a safety false positive).
🔍 Stylistic Patterns
The model tends toward a "commercial stock photo" aesthetic. In the Photorealistic People & Portraits category, evaluations noted a "slightly waxiness" or "too perfect" skin texture (seen in Toddler Portrait). While visually pleasing, it sometimes lacks the gritty texture of raw photography.
Best Model Analysis by Use Case
🏆 Best Use Case: Graphic Design & Branding
GPT Image 1.5 is the undisputed champion for design professionals.
- Why: It understands abstract concepts and layout composition better than competitors.
- Proof: The Quantum Leap Logo achieved a perfect 10/10 for capturing abstract concepts of speed and connection with high-quality 3D rendering.
- Recommendation: Use this model for logos, app icons, social media assets, and any task requiring legible text.
🏢 Excellent Use Case: Architecture & Interiors
For architects and interior designers, this model offers near-perfect visualization.
- Why: It handles lighting, materials, and perspective with photorealistic accuracy.
- Proof: The Scandinavian Living Room scored a 10/10, indistinguishable from a real photograph.
⚠️ Use with Caution: Character Anatomy
- Issue: While simple portraits are fine, complex poses break the model.
- Example: The High-fiving image (Score: 3) and Lecture Hall (Score: 5) both suffered from severe hand/limb hallucinations.
🚫 Avoid: Copyrighted Art Styles
- Issue: Do not use this model if you need to mimic a specific copyrighted animation style (e.g., Studio Ghibli, Disney).
- Reason: You will likely encounter safety refusals, as seen in the failure to generate the Ponyo style sea creature and Princess Mononoke style.
