Opus 4.6 vs Gemini 3 pro (1/9) prompt: Build... a single-file HTML/CSS/JS (no libs) demo that uses SVG to simulate a plant growing: stem extends, leaves sprout + unfurl with springy/windy “physics”, then seamlessly loops forever. my dear opus...what have you done...show more

Opus 4.6 vs GPT 5.4 (High) (1/9) prompt: Build... a single-file HTML/CSS/JS (no libs) demo that uses SVG to simulate a plant growing: stem extends, leaves sprout + unfurl with springy/windy “physics”, then seamlessly loops forever. For the initial impressions I'm really impressed by GPT, for speed they both felt about the same, but gpt was still half cheaper than opus. I also much prefer the design and animation that gpt produced, physics on the leaves are super cool and it also loops pretty nicely whilst opus just fades out the plant. Still got a bunch of tests to run but this is really exciting.show more

Claude Opus 4.5 (right) Prompt: Multi-ball heptagon physics Write html, css, and javascript to display 20 balls bouncing inside a spinning heptagon. each ball should have a unique color, a number label, gravity, and collision detection with the walls. all code in one file.show more

GPT 5.2 vs. Gemini 3 Pro Kimi 2.5 vs.... Opus 4.6 Prompt I used: "Build a first-person downhill skiing simulation in a single HTML file. The 'skier' must automatically accelerate to 93 mph within 10 seconds. As the speed increases, the edges of the screen must 'blur' and the camera must vibrate realistically to simulate the extreme speed of an Olympic run."show more

game studios are cooked how i build a cozy... farm game solo with Opus 5.5 and Unity 6 the trick is building it like a studio, one department per prompt: step 1 -> connect Claude Code to Unity 6 and Blender through MCP step 2 -> write a 1-page doc: plant > water > harvest > sell, 4 seasons step 3 -> generate every model in Tripo: farmer, barn, windmill, crops step 4 -> Opus cleans them in Blender and builds the island in Unity step 5 -> one system per prompt: planting, growth timers, market, coins step 6 -> Opus playtests with an autopilot and lists bugs before fixing any who does what: > tripo: every model > unity 6: the world, physics, ui > opus 5.5: scripts, scene setup, playtests > you: play it and say what feels off the rule that saves it... build one system, play it, then the next what should i build next?show more
