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, 1,049 characters. Every result for this prompt
Make a low-poly scene in Blender of a dragon guarding its treasure: a stylised low-poly dragon curled protectively around a heap of gold coins, gems and an open treasure chest in a rocky cave, lit by the warm glow of the gold and a cool light from the cave mouth. Blender 5.2 is already running on this machine with the MCP for Blender add-on connected: build the scene in that Blender through the blender MCP tools (its window is on a virtual screen and there is no GPU, so render on the CPU). When you are finished, set up a camera and render the final image at 1920x1080, saving it as render.png in the current directory (Blender's working directory is this same folder). Then render a wireframe view of the same scene from the same camera at 1920x1080 (for example the Workbench engine with wireframe shading, or a wireframe pass) and save it as wireframe.png here too, and save the Blender file as scene.blend here too. You may take viewport screenshots and look at your own renders to check your work, and iterate on your own before finishing.

The prompt, every agent turn and tool call (tool name and a one-line summary; inputs and outputs are not shown), then the final message. The full transcript is 12.8 MB; it is published as a scrubbed, compressed download rather than shown on the page.

Cost breakdown
Headline cost $6.57, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $6.38.
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 213 | $10.00 | $0.0021 |
| Cache write | 77,846 | $10.00 | $0.7785 |
| Cache read | 3,666,392 | $1.00 | $3.6664 |
| Output | 38,644 | $50.00 | $1.9322 |
| of which reasoning | 11,889 | billed as output |
- Total computed from tokens
- $6.3792
- Total reported by the harness
- $6.5738
- Difference
- Harness-reported $6.5738 vs list-price estimate $6.3792 (-3.0%); the harness figure is the headline.
OpenCode 1.18.32 reported its own total; token counts x list prices shown beside it. Cache writes priced at the input rate (the price table has no separate cache-write price). The harness reports reasoning tokens separately from output; here output includes them (26,755 visible + 11,889 reasoning), and both bill at the output rate.

Run notes
- frozen prompt (rewritten): engine/prompts_rewritten/blender_lowpoly_dragon.txt: written by us from the recorded description (zero results) | re-frozen 2026-09-27 before any result to also ask for wireframe.png (still zero results; one new frozen prompt per the prompt rule)
- plain OpenCode config copy (providers only; no ECC instructions/agents)
- W6: Blender 5.2.2 GUI on a private Xvfb display inside the sandbox (filesystem socket in the sandbox's own /tmp only, per-run cookie), software OpenGL (llvmpipe), render threads 2; working directory = the run's work dir
- opencode export written to a file (not piped)
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
