The model's own page, run in a sandboxed frame only when you ask (a page that needs its own origin opens in a new tab on a separate demo site). Phones get a full-screen player capped at 1.5x pixel density (2x on larger screens) so it stays smooth; the original page runs uncapped. Tap inside for sound.

No rubric for this prompt
Visitor votes and reviewer grades are not available yet.
- AI judge
- AI judge: the test runner (model claude-opus-5-5), scoring by visual review of the 1600 px render against the pre-registered rubric. No AI-judge score exists for this result: there is no rubric for this prompt, so no score is shown and none is made up.
- Visitors
- Public voting with a blind reveal is coming: you score the output first, then see the other scores.
- Reviewer
- The reviewer's own grade appears here once it is added.
Scores compare results for the same prompt only. AI-judge boards rank runs within one prompt, equal totals sharing a rank; scores from different prompts are never averaged.

The exact prompt
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.

Run notes
- frozen prompt (written): written 2026-10-01 for the MR new-categories expansion (owner request: expand model review with new kinds of tests); category algorithm_visualizers; zero results
- plain CODEX_HOME copy (config.toml only, run work/ trusted; no AGENTS.md/skills/state)
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Isolation audit: outside paths seen
- Renderer: inline SVG + DOM/CSS, no canvas (first <svg> at index.html line 324; SVG elements created with createElementNS); single self-contained index.html, no CDN and no external assets.
- Card video: the run's own 8 s session capture (headless Chromium, no GPU), re-encoded as H.264. Poster: the run's own render.png.
- 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.
