Code Generation Showdown: Gemma 4 vs Qwen 3.6 on a Consumer GPU — Same Prompt, Four Models, One Shot

All models share a common base: full GPU offload, flash attention, q4_0 KV cache, context-shift enabled, single slot. Gemma models get additional tuning flags.

Key flags: -ngl 99 (full GPU offload), -fa on (flash attention), -np 1 (single slot), -ctk/-ctv q4_0 (quantized KV cache to fit larger context windows), --context-shift (handles context overflow gracefully). Gemma models use --kv-unified for its iSWA architecture. See the Gemma 4 context window post for why Gemma MoE gets 262K while Dense is limited to 65K.

Create a single standalone index.html file that simulates the solar system using Three.js loaded from a CDN.

Requirements:

• Sun at the center with emissive glow
• All 8 planets orbiting at different speeds and distances
• Earth has a Moon orbiting it
• Saturn has visible rings
• Realistic relative sizes (not to scale with distances — make it visually appealing)
• Ambient starfield background
• Smooth orbital animation
• OrbitControls for camera (zoom, pan, rotate)
• Dark background, good lighting
• Labels for each planet (HTML overlay or sprite)
• Responsive, fills the full viewport

Output ONLY the complete HTML file, no explanation before or after.

Create a single standalone index.html file that renders a realistic 3D model of a Formula 1 car using Three.js loaded from a CDN.

Requirements:

• Build the car geometry procedurally (no external model files) — use combined Three.js geometries (boxes, cylinders, spheres, extrusions, etc.)
• Realistic F1 proportions: long narrow nose, wide front and rear wings, side pods, cockpit opening, rear diffuser, halo device, large rear wing with DRS-style flap
• Four low-profile tires with visible rims
• Red livery with white/black accents (Ferrari-inspired)
• Metallic/glossy materials with proper lighting reflections
• Ground plane with subtle grid or shadow
• Environment lighting (HDR-style) for realistic reflections — use PMREMGenerator or similar
• Smooth camera orbit (OrbitControls) with good default angle
• Responsive, fills the full viewport, dark background
• The car should be centered and properly scaled

Create a single standalone index.html file that shows an animated panda eating bamboo using p5.js loaded from a CDN.

p5.js quick reference:

• Load via: <script src="https://cdn.jsdelivr.net/npm/p5@1.9.4/lib/p5.min.js"></script>
• Define setup() to initialize canvas: createCanvas(windowWidth, windowHeight)
• Define draw() for the animation loop (runs ~60fps)
• Drawing primitives: ellipse(x,y,w,h), rect(x,y,w,h), arc(x,y,w,h,start,stop), triangle(), line(), bezier(), quad()
• Colors: fill(r,g,b), stroke(r,g,b), noStroke(), strokeWeight(n), background(r,g,b)
• Transforms: push()/pop(), translate(x,y), rotate(angle), scale(s)
• Math: sin(), cos(), map(), lerp(), noise(), random(), millis(), frameCount
• Text: textSize(n), textAlign(CENTER), text(str,x,y)
• Use windowResized() with resizeCanvas() for responsive sizing

Requirements:

• A cute cartoon panda character (black and white, round body, ears, eye patches, arms, legs)
• The panda is sitting and holding a bamboo stalk
• Animate the panda chewing: mouth opens and closes rhythmically, head bobs slightly
• The panda’s arm moves the bamboo toward/away from the mouth in sync with chewing
• Bamboo stalk drawn with segments, nodes, and a few leaves
• Peaceful background scene: soft gradient sky, rolling green hills, a few bamboo stalks in the background
• Subtle ambient animations: leaves swaying, clouds drifting, maybe butterflies or fireflies
• Smooth, looping animation using sin/cos for organic movement
• Responsive canvas that fills the viewport
• No external assets — everything drawn procedurally with p5.js primitives

Create a single standalone index.html file that renders a 3D scene of a cartoon giraffe riding a bicycle using Three.js loaded from a CDN.

Three.js quick reference (r160+, ES modules only):

• Import map: <script type="importmap">{"imports":{"three":"https://unpkg.com/three@0.160.0/build/three.module.js","three/addons/":"https://unpkg.com/three@0.160.0/examples/jsm/"}}</script>
• Use <script type="module"> with: import * as THREE from 'three'; import { OrbitControls } from 'three/addons/controls/OrbitControls.js';
• Geometries: BoxGeometry, SphereGeometry, CylinderGeometry, TorusGeometry, TubeGeometry(curve, segments, radius, radialSegments, closed), RingGeometry, ConeGeometry, LatheGeometry(points, segments)
• Curves for tubes: CatmullRomCurve3([Vector3, …]), QuadraticBezierCurve3(v1,v2,v3)
• Materials: MeshStandardMaterial({color, roughness, metalness}), MeshPhysicalMaterial({…clearcoat})
• Environment: use PMREMGenerator + RoomEnvironment from ‘three/addons/environments/RoomEnvironment.js’ — call pmremGenerator.fromScene(new RoomEnvironment()).texture, do NOT call compile() or compileEquirectangularShader()
• Groups: new THREE.Group(), group.add(mesh)
• Transforms: mesh.position.set(x,y,z), mesh.rotation.set(x,y,z), mesh.scale.set(x,y,z)
• Shadows: renderer.shadowMap.enabled=true, light.castShadow=true, mesh.castShadow=true, ground.receiveShadow=true
• Animation: use requestAnimationFrame loop, THREE.Clock for elapsed time
• IMPORTANT: In ES modules (strict mode), never assign to undeclared variables. Never redeclare const/let variables. Declare all variables before use.

Requirements:

• Build everything procedurally (no external model files) — use combined Three.js geometries
• GIRAFFE character (cartoon style):
  • Tall long neck made of cylinders/tubes, yellow-orange body color with brown spots (use small brown sphere/box meshes scattered on the body and neck)
  • Rounded body (ellipsoid/scaled sphere), four legs with hooves
  • Head with two small ossicones (horns), ears, big friendly eyes, snout
  • The giraffe is SITTING on the bicycle saddle, legs reaching down to pedals
  • Legs should animate: pedaling motion (rotating with the cranks)
• BICYCLE:
  • Simple bicycle frame (diamond shape from tubes/cylinders)
  • Two wheels with spokes (TorusGeometry for tires, CylinderGeometry for spokes radiating from hub)
  • Handlebars, saddle, pedals with cranks
  • Wheels should spin as the giraffe pedals
  • The giraffe’s front legs/hooves grip the handlebars
• ANIMATION:
  • Pedaling animation: cranks rotate, giraffe legs follow, wheels spin in sync
  • Gentle swaying/bobbing of the giraffe’s body as it pedals
  • Optional: slight head bob, tail swish
• SCENE:
  • Green ground plane (grass-like color)
  • Soft lighting with shadows
  • Light blue or gradient sky background
  • OrbitControls for camera
  • Responsive viewport
  • The scene should be cheerful and whimsical
