Astra kept making the cars look ridiculous, so I gave in and used free 3D models made by actual artists 😂
This is Spline Rush now. 6 cars, 6 tracks, 3 minutes of gameplay.
Built with ChatGPT 6 Astra Ultra, @threejs and @WebGPU.
@blueemi99 What is good in having a extremely powerful model but not being able to use it as it using all your usage in few prompts?
OpenAI direction is genius, you can basically use sol 6 with 20x plan in heavy mode and you will last more than just 2 freaking day's 😂
Building ToolBraid Companion: an open-source WebMCP extension + Windows companion that lets Codex/MCP agents work across real pages, desktop controls, files and repeatable workflows. One measured X task used 83.9% less context. I’d use Devin to take it from RC to production.

@bridgemindai Best decision 👏🏻
Grok was over hyped and now is just another flop...
I don't understand why the fk they don't just release something good already instead of these low quality models. Opensource models are way better then Grok
👀New Azure AI Playground entries spotted:
GPT-6 Sol
GPT-6 Luna
GPT-6 Astra Minor
Nothing official yet, but it sure looks like OpenAI is preparing the next GPT-6 lineup. 🔥
@thsottiaux@OpenAI@OpenAIDevs
Things might get interesting very soon. 🔥

This is Spline Rush now. 6 cars, 6 tracks, 3 minutes of gameplay.
Built with ChatGPT 6 Astra Ultra, @threejs and @WebGPU.
Build a complete, production-quality browser racing game called Spline Rush using the latest Three.js (WebGPURenderer + TSL where possible). 100% procedural: no external models, textures, audio files or fonts. Everything generated in code at runtime.
CORE GAME
- 6 unique tracks with elevation, banking, tunnels, hairpins, named corners and distinct biomes (coastal day, mountain dusk, desert sunset, forest rain, night city neon, high-speed oval).
- Championship mode (qualifying + 3 races), Time Trial with ghosts, Quick Race.
- 8 AI opponents with personality, racing line, braking points, overtaking and defending.
- Best lap records, sector times, live event feed, replay camera.
- Garage: 5 parametric cars with clearcoat + metal-flake paint, panel gaps, working lights, animated suspension, damage states.
GRAPHICS TARGET (Ultra, worthy of RTX 5090 at 4K)
Renderer: THREE.WebGPURenderer. Physically based pipeline.
Lighting:
- Rayleigh/Mie physically based sky + starfield + moon + dynamic sun that drives a full day/night cycle.
- Cascaded shadow maps (4 cascades, stable texel snapping, high-res).
- IBL via PMREM updated with time of day.
- Volumetric fog + god rays + heat haze.
Materials:
- MeshPhysicalMaterial / TSL nodes: clearcoat, anisotropy, transmission on glass, metal-flake paint, wet-road shader that reacts to rain.
Post-processing chain (RenderPipeline / TSL or postprocessing library):
GTAO or high-quality SSAO → SSR → bloom (Karis) → motion blur (velocity) → DOF → god rays → auto-exposure → color grading + film grain + vignette → SMAA or TAA.
Effects:
- GPU particle pools: tyre smoke, sparks, dust, rain spray, grass/gravel kick-up, heat distortion.
- Skid marks that persist and fade.
- Dynamic wetness and puddle reflections when raining.
PHYSICS & FEEL
- Fixed-step 120 Hz simulation.
- Raycast or strut suspension, load transfer, combined-slip tyres, ABS/TC, surface types (asphalt, kerb, grass, gravel, wet).
- Camera: cinematic chase + hood + onboard with motion and collision shake.
AUDIO
- Fully synthesised Web Audio: multi-layer engine by RPM/load, wind, tyre screech, kerb rumble, crowd, dynamic music.
QUALITY SYSTEM
- Presets: Low / Medium / High / Ultra.
- Ultra assumes RTX 5090-class GPU: 4K, high shadow maps, max particles, all post effects on, no aggressive LOD.
- Adaptive quality that can drop effects if frame time exceeds target.
Start with a playable first version (one track, one car, basic lighting), then iterate feature-by-feature exactly as requested. Keep everything in a single clean HTML/JS (or Vite) project that runs locally. Comment major systems. Make it look expensive, not cute.
I received many messages about "what prompt have i used" to have this results with Astra.
Now maybe some of you will understand why for some the game is lagging 😅
Prompt is below:
