Kimi K3: four real builds, four real prices - $0.035 to $2.90

Four separate /design runs with Kimi K3 in Command Code, posted on X as they happened: a developer portfolio for $0.035, a chase-cam racing game for $0.97, a first-person shooter for $2.10, and a voxel sandbox game for $2.90.

Four different one-shot /design sessions with Kimi K3 in Command Code, posted on X as they happened over the same couple of weeks. No cherry-picked "best of," just four real prices for four real briefs.

$0.035 - a developer portfolio

I'm so impressed with Kimi K3. The result is impressively good, only $0.035, and it produces an actual developer portfolio....

Prompt:

Design an Awwwards-winning personal portfolio website for a frontend developer/creative. Dark minimalist aesthetic, bold elegant typography, immersive hero section, smooth scroll animations, micro-interactions, and creative transitions. Sections: Hero, Selected Works (with filters), About, Process, Contact and gimme a downloadble .html file

$0.97 - a chase-cam racing game

kimi k3 + /design skill in command code is quite good. k3 builds and designs super well without wasting tokens when used with the right coding agent....

Prompt (trimmed):

Create a complete single HTML file for a fun modern car racing game using HTML5 Canvas with a wide canvas (700x700)... realistic car physics including acceleration, deceleration, braking, smooth steering with momentum and realistic drifting when turning at high speed... a smooth, cinematic third-person view directly behind the car. make it as realistic as you can, like a real car game from every aspect

$2.10 - a first-person shooter

WTF. Kimi K3 with /design in Command Code just made me a full fledge game for just $2.10. THIS IS INSANE!!! ...

2:02 PM·Jul 24, 2026

Prompt (trimmed):

Create a fun, complete first-person shooter game in the browser using JavaScript and Three.js... Smooth first-person movement (WASD, mouse look, jump, sprint) with Pointer Lock. Shooting system: Multiple weapons (pistol, rifle, shotgun, sniper) with recoil, different fire rates, ammo, and reload... Enemies: Several types that chase, shoot, or attack the player... Levels: 3-4 arenas or waves... Polish: Muzzle flashes, bullet impacts, simple lighting, background music, and sound effects.

$2.90 - a voxel sandbox world

Kimi K3 is impressively good. I built a COMMANDCRAFT games inspired from minecraft...

11:29 PM·Jul 17, 2026

Prompt (trimmed):

Build a playable voxel sandbox game as a browser-based web app using JavaScript + Three.js (WebGL)... Chunk-based procedural world (16x16x128 chunks) using Perlin/Simplex noise for terrain... Basic biomes (plains, forest, hills) with trees and surface variation... Voxel block system with 15-25 core blocks... First-person player: WASD + mouse look, jumping, gravity, block collision. Break blocks (left click) and place blocks (right click) with raycasting... Crafting: 2x2 inventory + 3x3 crafting table with 15+ basic recipes... Survival mode basics: Health/hunger, day/night cycle, simple mob spawning at night.

What this actually shows

None of these four is a controlled comparison - different briefs, different complexity, no re-rolls to check variance. What they do show, together, is a price curve: cost scaled roughly with scope. A static portfolio page cost fractions of a cent. A physics-heavy racing game with a scrolling road cost under a dollar. A full FPS with multiple weapons, enemy AI, and level progression cost a couple dollars. The most ambitious build - a chunked, proceduraly-generated 3D voxel world with crafting and a day/night cycle - cost the most, and still landed under $3.

For a coding agent that's routinely priced in fractions of a cent per interaction, a $2-3 ceiling on "build me an entire game genre from scratch, one shot" is the number worth remembering.
