GLM-5.3 in OpenCode 1.18.32

Poster frame of GLM-5.3's page
Open the original page

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. It starts in its auto-tour (T switches to play mode on a keyboard).

No verdict yet.

The full review

Stopped by us. Stopped by us (box row cap reached (2841s); stopped by the box lane so the run ships as partial); not a model failure.

Not scored: only runs that finished on their own are scored.

The exact prompt

as run, 971 characters. Every result for this prompt

Design a giant desert sandworm re-engineered as a robot, presented as an engineering blueprint. Deliver ONE self-contained index.html (SVG and/or canvas, inline CSS and JS, no external assets, libraries or fonts). It must include: an animated robotic worm that moves through sand, with segments that articulate as it burrows and surfaces; a labelled segment-by-segment mechanical breakdown (for example head and mouth assembly, drive segments, sensor ring, power core, tail) with callouts naming each part and what it does; a cross-section diagram of the mouth showing the grinding and intake mechanism; and a terrain and operations map showing the worm's route, depth and working zones. Everything must share one cohesive blueprint style: blueprint-blue background, white and cyan line work, grid, dimension lines, title block and technical lettering. It must look good on desktop and phone. Write everything into the working directory and finish with a short README.md.

Cost breakdown

Headline cost $2.67, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $2.67.

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 (39,106 visible + 101,359 reasoning), and both bill at the output rate.
