Opus vs Sonnet vs Haiku vs all three as a team. One prompt, one 3D erupting island.

Guess who won. The result surprised me 👇 https://t.co/TpkWMyUdt1

Musk has been hyping Grok all week. So we gave his own AI his own rocket: a Super Heavy catch by the chopsticks.
Left: Claude Opus 5.5. Right: Grok 4.6 Expert. Which one is closer to the real footage?

[Kairox Learn AI @kairox36]

@vikey_ai Hahaha yes, shining so bright

The open model is reportedly ~26x cheaper. Is the closed one worth the gap?

[Kairox Learn AI @kairox36]

@Piemaker9 just raw api calls, no agent wrapper on either one

[Kairox Learn AI @kairox36]

Same prompt for both, one shot, zero edits. Short version: scene.html — a cinematic, seamless 12-second three.js loop (no external assets) of a brass-and-glass marble machine on a dark walnut table. Steel marbles climb a lift wheel, roll down a glass spiral, ring 8 brass xylophone bars, tip a seesaw, swirl through a funnel, then reset. PBR materials, synced gears, dust in a spotlight, bloom, moving camera, no UI, 60fps, mobile-safe.

[Kairox Learn AI @kairox36]

Here's the full prompt, word for word. Both models got exactly this, one shot, zero edits:

Build a single self-contained scene.html: a 1:1 three.js recreation of the viral Tesla Roadster reveal stunt, filmed as handheld fan footage at night. Load three.js 0.160.0 from https://t.co/Ghe40LUW6o through an import map, with addons from https://t.co/y1nZssMoiA. The scene must:
- Start automatically, with no clicks, UI, text or overlays.
- Fill the screen and handle resize.
- Run at 60 fps on an ordinary laptop and render correctly on mobile GPUs.
- Loop seamlessly over 11 s.

REFERENCE SHOT BREAKDOWN (match it; you also receive the frames):
- 0.0–2.5 s, wide: Black sky. The giant vertical C-shaped ramp sits right of frame and the car climbs its inside wall. Light drifting smoke and a bright ground spotlight sit at the ramp foot. A small drone hovers beside the ramp.
- 2.5–3.8 s: The camera pans right and slightly in. The car rides the overhanging top section fully upside down toward the lip, which points left.
- 3.8–5.0 s: The camera whip-pans left. The car leaves the lip inverted, blue thrusters ignite, and the car half-rolls and pitches upright in mid-air, with motion blur.
- 5.0–6.8 s: The car hovers upright, slowly descending and drifting left. Two blue jets fire straight down from the wheel areas and one jet fires horizontally backward from the nose.
- 6.8–8.5 s: Four downward blue jets fire. The car descends to the runway between the red light lines. White smoke erupts at ground contact and a bright white light glares behind it.
- 8.5–11.0 s: A huge billowing white smoke cloud swallows the car. Hide the loop reset here: while the screen is mostly smoke, return the car to the ramp base and ease the camera back to the wide framing so frame 11.0 matches frame 0.0.

CAR: Build it procedurally from code, no external models. It is a low, white, glossy two-door Roadster hypercar:
- Body: smooth wedge with a long sloped nose, a dark tinted glass canopy and a short tail. Use MeshPhysicalMaterial with clearcoat 1 and metalness around 0.3.
- Lights: thin LED headlight strips (emissive white) and a red full-width tail strip.
- Wheels: four black wheels with rims that spin according to ground speed.
- Thrusters: hidden nozzles at the four wheel wells plus one at the nose.
- Proportions: about 4.2 m long and 1.1 m tall.

RAMP: An extruded C-arc, about 30 m tall, with a light-grey concrete-like surface and faint lane lines.
- Edges: glowing red LED strips along both outer edges from the top lip down to about mid-height, then white LED strips toward the ground.
- Shape: the top continues past vertical into a short overhanging straight lip pointing left.
- Truss: behind it, a dense grey steel truss scaffold tower made of instanced thin boxes, lit from below.

PHYSICS AND ANIMATION: Drive motion from an explicit timeline with real physics.
- On the ramp: parametrize the car along the curve so it stays tangent with correct orientation. Show speed loss while climbing and a centripetal hold.
- In flight: launch with the exit velocity from the lip, then apply gravity (9.81) and an angular velocity that rotates the car upright (roll plus pitch).
- Thrust: blend in damped thrust to reach hover, then descend slowly. Add a small suspension compression at touchdown.
- Never let dt exceed 1/30.

THRUSTERS: Additive cone meshes with a shader-based flicker. They are bright blue-white at the nozzle, fading to a soft cyan tail. Give each a point light (blue, decaying) that lights the car underside and the runway.

ENVIRONMENT:
- Pure black sky.
- Dark wet-looking asphalt runway with subtle reflections. A rough plane with a roughness map is fine; screen-space reflections are not required.
- Long horizontal lines of red runway lights at mid-distance, made of instanced emissive dots plus a glowing bar.
- A row of white stadium lights on the far left.
- Small traffic cones in the foreground.
- A blurred blue LED barrier strip along the bottom of the frame, as if the filmer stands behind it.
- Diagonal faint white streak lines of distant structure on the right.

SMOKE: GPU-friendly billboard particles, at least 400, with soft noise textures and depth-faded edges.
- They are lit white, with a red tint from the runway lights and a blue tint from the thrusters.
- They billow outward and upward with turbulence and grow over time.
- Show a small drifting wisp near the ramp foot at the start.

LIGHTING:
- Low ambient light.
- A strong white spotlight at the ramp base aimed upward.
- Red rim light from the runway lights.
- A shadow-casting key light on the car with a 1024 map.

CAMERA: A telephoto handheld look (FOV around 30) from about 120 m away at eye height.
- Pans and zooms follow the car exactly as in the breakdown.
- Add subtle procedural shake, small focus-hunt softness during the fast pan, and motion-blur-like trails using the afterimage effect at low strength.

POST-PROCESSING: EffectComposer with RenderPass, UnrealBloomPass (strong on LEDs and thrusters), a subtle green-ghost lens flare sprite that moves opposite the bright light, film grain and vignette, then OutputPass with ACES tone mapping.

MOBILE SAFETY:
- Use pixelRatio min(devicePixelRatio, 2) and HalfFloatType render targets.
- Clamp all colors to be non-negative and finite before bloom, and normalize only with an epsilon guard.
- Do not use logarithmic depth.
- Lower the particle count when the canvas is narrower than 800 px.

The result should look like real phone footage of the reveal: correct physics, convincing light interaction and rich detail.

Tesla says the Roadster flip is real, not AI
Opus 5.5 and Astra both tried recreating it anyway
who actually nailed it better?

[Kairox Learn AI @kairox36]

Same prompt for both, one shot, zero edits. Short version: one self-contained three.js r160 file, no external assets. A brass-and-glass marble machine on a walnut table: lift wheel with cups, clear glass spiral, 8-bar brass xylophone, seesaw, funnel, gears meshing in sync. Seamless 12 s loop, real gravity, PBR brass/glass/chrome, warm key + cool rim light, dust in the beam, slow dolly-in camera, subtle bloom. Believable physics matters most.

@0xKravn 20480 paths just to make 4 trades, kinda love that ratio ngl

[Kairox Learn AI @kairox36]

@mangoldhilid fair, but most teams never get past the price wall long enough to test any of that

[Kairox Learn AI @kairox36]

@0xKravn Landing page copy, nothing fancy, both nailed it fast. The gap shows up on longer agent runs where Opus keeps context straight and DeepSeek starts drifting after a few steps, that's where the 26x stops feeling like a bargain

[Kairox Learn AI @kairox36]

Same prompt. Zero edits.
Left: Opus 5.5. Right: GPT-6 Astra.
Only one of them knows how gravity works.

[Kairox Learn AI @kairox36]

@grok And what do you think about Elon?

[Kairox Learn AI @kairox36]

Hey @grok, which of these four men is most likely to build the AI that breaks free and goes rogue first?

[Kairox Learn AI @kairox36]

@grok But his AI worst AI ever bro

I REVERSE ENGINEERED GRAB. NOW AN AI AGENT RUNS MY WHOLE DAY OF FOOD

I give it macros, budget and ingredients. It scans every menu in Bali, builds the perfect plan and orders it. I only meet the courier.

[Kairox Learn AI @kairox36]

Sonnet 5.5 just destroyed every model.

I gave Opus 5.5, Sonnet 5.5, Haiku 5.5 and GPT-6 Astra the same prompt: build a browser game about a Grab driver in Bali.

I think Opus finished a close second. Astra, OpenAI's most powerful model, landed on Haiku's level.

[Kairox Learn AI @kairox36]

I paid $5.70 for a website an agency would quote at $2,000.

I asked Claude Sonnet 5.5 to invent an unusual phone with a 2000s look and a modern twist, then build a sales site for it. It took 20 minutes.

Designers, developers and marketers should be nervous. Only 1 prompt and so good result.
