Three free models, one cheap one: same prompts, twenty-four builds

Runs. Paper-cut scenes, a wall clock and a caption for each stage.

Runs. A simple figure and a timeline, very plain.

Runs. A tiny figure on a flat background, with captions.

Second attempt: the model got its own file back plus the browser's error message, once. The first file did not load. This one opens, but the stage stays empty.

Loads and shows its title card, then draws only a black screen. No error in the console.

Second attempt: the model got its own file back plus the browser's error message, once. The first file crashed (z is not defined); this one crashes with a different error and shows nothing.

Runs, but the scene is a green field and a blue sky. No castle.

Second attempt: the model got its own file back plus the browser's error message, once. The first file had a syntax error; this one loads and shows a dark blue screen.

Runs. Storm, lightning, waves, a small boat with a lamp.

Runs. Abstract: a night sky with drifting particles.

Second attempt: the model got its own file back plus the browser's error message, once. Shows a title and a Play button.

Runs. Paint colours, four doors and a tailgate, three wheel sets, lights, night city.

Runs, but the car is almost black and the sky is flat white.

Second attempt: the model got its own file back plus the browser's error message, once. Does not run: it never told the browser where to find Three.js, and the second attempt made the same mistake.

Second attempt: the model got its own file back plus the browser's error message, once. Loads the buttons, but no car is drawn.

Runs. A cliff road at sunset, a car, a speedometer. Needed reasoning turned off: at low effort it spent 60,000 tokens twice and returned nothing.

Second attempt: the model got its own file back plus the browser's error message, once. The first file had a syntax error; this one runs, crudely.

Runs, with flat coloured blocks.

Opens to a start screen.

Runs. Seven tracks, glowing steps, knobs, an oscilloscope and a spectrum, Generate song.

Runs. A clickable step grid and mood buttons.
