DeepSeek V4.1 Flash in OpenCode 1.18.32

Zoom, inline player and more ways to view
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, 1,815 characters. Every result for this prompt
Build a working 1990s-style desktop operating system inside one web page. It needs a desktop with a wallpaper and icons, a taskbar with a start button, a start menu and a live clock, and real windows: each window can be dragged by its title bar, resized from its corner, minimised to the taskbar, maximised, restored and closed, and clicking a window brings it to the front. Include three working apps that open in those windows: a Notepad that edits text and saves to and reopens from localStorage under a file name; a Paint app with a pencil, brush sizes, a 16-colour palette, a flood fill and an eraser on a canvas; and a Calculator with the four operations, decimals, clear and a keyboard input path. Double-clicking a desktop icon or choosing an app from the start menu opens it. Several windows of the same app can be open at once. Everything is drawn with HTML and CSS (no images): bevelled grey buttons, a classic title-bar gradient and pixel-crisp borders. So the first view is not an empty desktop, on load the system shows a short boot screen (about 2 seconds) and then opens Notepad with a welcome note and the Calculator, cascaded. On a phone, windows open maximised and the taskbar stays usable. 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.

OpenCode 1.18.32 reported its own total; token counts x list prices shown beside it. The harness reports reasoning tokens separately from output; here output includes them (30,345 visible + 59,975 reasoning), and both bill at the output rate.

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 app_clones; zero results
- plain OpenCode config copy (providers only; no ECC instructions/agents)
- opencode export written to a file (not piped)
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Isolation audit: none
- Renderer: DOM + CSS desktop with a Canvas 2D drawing surface (getContext('2d') at index.html line 699); 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.
