Introduction: The Era of App-Building Models
In the ever-evolving tech landscape, AI models continue to push the boundaries of what's possible. With the recent launch of Grok 4.5 and updates to GPT-5.5 and Claude, it's time to explore how these models perform when tasked with building the same application. This comparative test highlights each model's strengths and weaknesses, focusing on three application scenarios.
First Challenge: The Interactive 3D Rubik's Cube
The first challenge was to create a 3D Rubik's Cube with 'scramble' and 'solve' buttons. This project required complex 3D math and smooth animations. The results? Claude Opus 4.8 and Fable 5 excelled, producing a correctly colored and animated cube on the first try. Grok 4.5 needed a second chance but eventually delivered a clean, colorful cube. GPT-5.5, however, failed to render a complete cube, showing only a dark face.
Key Points:
- Grok 4.5: Needed a second attempt
- GPT-5.5: Failed to render a complete cube
- Claude Opus 4.8 & Fable 5: Immediate success
Second Challenge: The Particle Sandbox
The second challenge was to create an interactive particle sandbox. This project aimed to produce a visually captivating simulation with particles and attractors. GPT-5.5 shone here, with neon attractors and colorful trails, while Grok 4.5 took a more orderly approach with attractor rings. Fable 5 leaned into glowing orbs, and Opus 4.8 delivered an intense physical simulation but was less visually appealing.
Key Points:
- GPT-5.5: Winner on visual appeal
- Grok 4.5: Orderly approach
- Claude Opus 4.8: Intense physics
Third Challenge: The Playable Breakout Game
The last challenge was to develop a Breakout game where the paddle follows the mouse and the ball breaks colorful bricks. Each model produced a playable version, but differences emerged in gameplay fluidity and aesthetics. Performance details will be analyzed in a future article.
Conclusion: Choosing the Right Model
Each model has its own strengths. Claude stands out for handling complex animations, while GPT-5.5 excels in creating visually captivating interfaces. Grok 4.5, though slightly behind, shows promising potential with some adjustments.
