Kimi K3 in OpenCode 1.18.35

as run, 1,074 characters. Every result for this prompt

Build a real-time 3D world in Three.js that looks like a living impressionist oil painting (one HTML file, CDN imports only, no external assets or textures; everything procedural). The whole frame must read as painted, not as a 3D render with a filter: a brush-stroke post-process (oriented, varied-size strokes that follow surface direction and color, visible canvas grain), a painterly sky with broken-color clouds, water with dappled reflections of the sky and shore, and a small landscape (garden, footbridge or shoreline, trees, flowers). Add falling snow that is painted too, and flocks of birds flying through the scene. Include two or three painted figures; clicking one opens a short in-world dialogue in a hand-lettered caption style. Interactive camera (orbit plus a gentle walk mode), a time-of-day slider that shifts the palette from cool morning to warm dusk, and a toggle that compares the painted view with the plain render. Must stay smooth on a laptop and usable on a phone (touch controls, adaptive quality). It should feel like stepping into a painting.

Headline cost $2.10, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $2.10.

OpenCode 1.18.35 reported its own total; token counts x list prices shown beside it. The harness reports reasoning tokens separately from output; here output includes them (42,366 visible + 38,221 reasoning), and both bill at the output rate.

one prompt, agentic harness (self-review allowed)skills=on

• frozen prompt (written): core requirements sha256 1ddb514daa65, full harness prompt sha256 1ddb514daa65; exact prompt text used by the existing harness rows of this test on the runs branch (copied from threejs_impressionist_world__claude-code__opus-5-5-high__attempt1/meta.json, sha256 verified); Beta hal
• no TUI: the harness ran in its non-interactive mode, so there are no TUI screenshots; the timelapse is built from version renders only
• OpenCode config (providers only, permission allow-all except question; no agents/instructions) + both default skill kits in xdg/config/opencode/skill (skills=on)
• infra retries: 0
• in the published transcript the sandbox HOME directory is shown as <HOME>
• skills=on: 54 skills installed in the harness skill directory before launch (video-33 remotion-dev/skills + heygen-com/hyperframes@0b5db9da + f; web-threejs-21 [redacted]/ai-AI Model Reviewer skills/ (alpha/mr-homebar)@7521074d98c9).
• Mode: headless run mode (opencode run --format json), inside bubblewrap sandbox
• Isolation audit: none
• Renderer: three.js r160 WebGL (ES module via an importmap) loaded from the jsDelivr CDN plus Google Fonts, so the page is not fully self-contained; custom shaders; canvas 2D only for textures.
• Status: stopped by us. Stopped at the row cap (45 min) before the harness declared it finished; the page shown is what it had built by then.
• Skills on: the run had 54 skills installed (33 video + 21 web/Three.js), as its meta records.
• Kimi K3 served via Fireworks (OpenCode provider fireworks-ai).
• Same frozen prompt as the other rows on this test; configurations differ and all rows are unscored, so this is not a head-to-head result.
• Live demo: not published. The page it had written by the stop throws a WebGL shader compile error on load in any browser: its own fragment shader defines RRTAndODTFit, which three.js r160 already injects for ACESFilmicToneMapping, so the scene does not render. Poster: a headless-Chromium screenshot of that page taken at import (the run folder has no render.png).
