Google's Gemini 4 Argon is now on the API. So the same six short prompts (a life animation, a voxel castle, a short film, a 3D car showroom, a driving game, a music studio) went to Gemini 4 Argon, Claude Opus 5.5 and GPT-6.1 Sol, one request each. Everything runs in your browser.
A human life from first heartbeat to old age, every frame drawn by JavaScript on one canvas, with a score synthesised in the browser.
Paper-cut chapters on a timeline, eight stages in sixty seconds. Ran first time, no edits.
Opus 5.5, from the video-24 run. No edits.
GPT-6.1 Sol, from the video-24 run. No edits.
Thousands of instanced blocks, a day and night cycle and a fly camera.
About 294,000 instanced voxels, a time-of-day slider and a cinematic fly-around. It opens at dusk and is very dark at night: press High Noon. Ran first time. One marked text edit: its subtitle line was shortened to 'Voxel Academy of Wizardry'; the code is otherwise exactly what the model wrote.
Opus 5.5, from the video-24 run. No edits.
GPT-6.1 Sol, from the video-24 run. No edits.
The Last Lighthouse: a storm, a sweeping beam, a boat fighting for the harbour, dawn. Sound is synthesised too.
A title card with the line 'When the compass drowns, look for the stone that burns.' One marked fix: two words ran together (constLH_POS), which stopped the script. After the fix it plays, but the text cards render as big black boxes over the scene.
Opus 5.5, from the video-24 run, with that run's one marked fix.
GPT-6.1 Sol, from the video-24 run. No edits.
An original electric crossover modelled entirely in code: paint, doors, lights, wheels, a night city.
A dark-blue crossover on a studio turntable: paint finishes, four doors and a tailgate, three wheel styles, lights. Ran first time, no edits.
Opus 5.5, from the video-24 run. No edits.
GPT-6.1 Sol, from the video-24 run. No edits.
A stylised driving game with a convertible, traffic, a speedometer and engine sound.
A retro-neon coast road with a speedometer, drifting smoke and a Wiped Out screen when you hit the cliffs. It ran first time, no edits. One bug: the restart key on that screen throws an error, so reload the page to play again.
Opus 5.5, from the video-24 run, with that run's one marked fix.
GPT-6.1 Sol, from the video-24 run. No edits.
A step sequencer, synths, drums, effects and a button that composes a song.
Seven tracks, glowing steps, knobs, a live oscilloscope and spectrum, and Generate song. Ran first time, no edits.
Opus 5.5, from the video-24 run. No edits.
GPT-6.1 Sol, from the video-24 run. No edits.
