We tested Fable 5, Grok 4.5, GPT 5.6 Sol Ultra, and GLM 5.2 on the same arcade game prompt. This was the result : Claude Fable 5 - the smoothest gameplay of the four. fluid movement, no jank. Grok 4.5 - nailed the screen shake, particle explosions, neon cinematics. most visually dramatic build. GPT 5.6 Sol - the all-rounder. genuinely great gameplay experience, nothing broken, everything solid. GLM 5.2 - an open-weight model shipping a complete, playable build that held its own against three closed frontier models. Which one did you like the most?

prompt : Create a complete Space Invaders-inspired arcade game using ONLY a single HTML file. Requirements: - Everything must be contained in one HTML file (HTML, CSS, and JavaScript). - Do not use any external libraries, frameworks, assets, or CDN resources. - Use the HTML5 Canvas API for rendering. - The game should run immediately when the HTML file is opened in a browser. Gameplay: - Player controls a spaceship at the bottom of the screen. - Move left/right with A/D or Arrow keys. - Shoot with Spacebar. - Multiple rows of alien enemies move horizontally and descend after reaching screen edges. - Enemies fire projectiles at random intervals. - Player has 3 lives. - Score increases when enemies are destroyed. - Game ends when lives reach zero or enemies reach the bottom. - Winning occurs when all enemies are destroyed. Visuals: - Modern neon sci-fi aesthetic. - Smooth animations (60 FPS target). - Particle explosion effects when enemies are destroyed. - Background starfield with subtle movement. - HUD displaying: - Score - Lives - Current Level - Responsive canvas that scales with browser size. - Screen shake effect on explosions. - Flashing effects for hits. - Animated menu and Game Over screen. Audio: - Generate simple retro sound effects using the Web Audio API. - No external audio files. Game Features: - Increasing difficulty every level. - Faster enemies each round. - Occasional bonus UFO crossing the top of the screen. - Pause with P. - Restart after Game Over. - High score stored using localStorage. - Delta-time based game loop for smooth gameplay. - Clean object-oriented or modular JavaScript architecture. Code Quality: - Well commented. - Organized into logical sections. - Avoid global variables where possible. - Maintain good performance. Output: Return ONLY the complete HTML document enclosed in one ```html``` code block. Do not include explanations or markdown outside the code block. make a small version of the prompt

Fable does look the best. I like that grok's aliens are different characters and not just different colours but no animation & the screen shake would drive me nuts, i'd be turning that off or down. Interesting that GPT and GLM's aliens look the exactly the same even the animation, just size diff.

@BuildFastWithAI How long did each one take?

@BuildFastWithAI A year ago I made a bunch of arcade games with claude. I think it is time to revisit them with 5.6 and see if I can polish them up a bit.

@BuildFastWithAI What about time? Grok is extremely fast compared to the others on my tests.

@BuildFastWithAI Ngl GLM 5.2 did the best.

@BuildFastWithAI Can you share the prompt?

@BuildFastWithAI Fableは敵の色が少なく再現性が低く見えます。 Grokは偽物っぽさを感じます。 GPTが比較的インベーダーっぽいです

@BuildFastWithAI Run all four AI fables to use the best of each to create the optimal version. Using exactly what you perceived in your taste, you would come to a result that no other AI would match, precisely because it's the best of each AI.

@BuildFastWithAI why are glm and gpt the exact same except gpt is stretched
