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, 1,997 characters. Every result for this prompt
Build a dynamic programming visualizer centred on edit distance (Levenshtein). Show two words and the full DP table between them; fill it one cell per tick, for each cell highlighting the three neighbours it reads (left, up, diagonal), showing the candidate costs for insert, delete and substitute or match, and writing the minimum with a small pop. Colour the table as a heatmap as it fills. When the table is complete, trace back the optimal path from the bottom-right corner with a glowing line, then animate the alignment below: the first word morphing into the second letter by letter, with insertions, deletions and substitutions coloured and labelled, ending on the final distance. Beside it show a second, smaller panel solving the 0/1 knapsack problem (8 items, capacity 15) with the same cell-by-cell filling and a traceback that lights up the chosen items. Controls: two text inputs for the words, word-pair presets (kitten/sitting, intention/execution, sunday/saturday, algorithm/altruistic), speed slider, play, pause, step, reset, and a toggle to show the recurrence formula for the current cell. So the page is alive without input, on load it starts solving the first preset automatically and then cycles through the presets with a 3 second pause between them, forever, until the user touches a control. Make it the clearest explanation of dynamic programming anyone has seen. 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.

Cost breakdown
Headline cost $0.12, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $0.12.

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 (38,844 visible + 85,976 reasoning), and both bill at the output rate.

Run notes
- frozen prompt (written): written 2026-10-05 for the MR category expansion (owner request: 500 finished runs in every category); category algorithm_visualizers; 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: outside paths seen
- Renderer: DOM + CSS with inline SVG (no canvas); single self-contained index.html, no CDN and no external assets.
- Card video: the run's own 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.
