Qwen 3.8 Max in OpenCode 1.18.35

as run, 1,796 characters. Every result for this prompt

Build a sorting algorithm race: six panels side by side (a grid on narrow screens), each sorting its own copy of the same 60-element array drawn as vertical bars, with bubble sort, insertion sort, selection sort, merge sort, quicksort and heapsort running at the same time, one comparison or write per tick. Highlight the bars being compared and the bars being written in each step, and show live counters for comparisons and array writes in every panel. When a panel finishes, play a quick sweep across its bars and stamp its finishing place (1st to 6th). Controls: input presets (random, nearly sorted, reversed, few unique values), a speed slider, play, pause, single step and reset; an optional soft tone per comparison through WebAudio that is off by default, with a mute toggle. After every race, show a small table of comparisons and writes per algorithm for that input. So the page is alive without input, on load it shuffles and starts a race on the random preset automatically, and after each finish it waits 3 seconds and races the next preset in turn, forever, until the user touches a control. Make it clear and beautiful, the kind of visual a teacher would put on a projector.

Save it as index.html in the current directory: one self-contained file with inline CSS and JavaScript only, no libraries or frameworks, and no external requests of any kind (no CDNs, web fonts, images or audio files). It must work when opened directly from disk, fit any window from a 390 px wide phone to a desktop, and run without console errors. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.

Headline cost $0.81, as reported by OpenCode (its own bill for the run).

Total reported by the harness

$0.8055

OpenCode 1.18.35 reported its own total; token counts x list prices shown beside it. No list price for qwen3.8-max in config/prices.json; no estimate computed. The harness reports reasoning tokens separately from output; here output includes them (13,483 visible + 38,320 reasoning), and both bill at the output rate.

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

• frozen prompt (written): core requirements sha256 3bebef2fdf85, full harness prompt sha256 3bebef2fdf85; exact prompt text used by the existing harness rows of this test on the runs branch (copied from algoviz_sorting_race__claude-code__haiku-5-5__attempt1/meta.json, sha256 verified); Beta half of the MR
• 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: canvas 2D (the sorting race is drawn on a <canvas> with getContext('2d') by the page's own script); sound through WebAudio; no library, nothing loaded from a CDN (single self-contained file).
• Card video: the run's own video.mp4 (H.264 yuv420p, unchanged). Poster: the run's own render.png.
• Skills on: the run had 54 skills installed (33 video + 21 web/Three.js), as its meta records.
• Qwen 3.8 Max 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.
