The $200 question: GPT-6.1 Sol vs Claude Opus 5.5
SemiAnalysis says Claude Max gives you about five times more API-equivalent usage than ChatGPT Pro for the same $200. More usage only matters if the output is good, so we gave the models behind the two plans, GPT-6.1 Sol and Claude Opus 5.5, the same four prompts, in the style of the leaked GPT-Next tests. One request each, word for word. Everything runs in your browser.
A racing game
A neon hover-racing game with five AI rivals, three laps, boost pads and a minimap.
A floating neon circuit with a tunnel of rings, banked turns, five rivals, a minimap and a boost meter. No edits.
Fast, with drifting and boost pads; the glow is so strong that much of the screen burns white. Second run (reasoning low): on medium, Opus spent its whole 64k output on thinking and returned no file. No edits.
A kitchen that works
A 3D kitchen where everything important works when you click it: fridge, oven, hob, tap, kettle, toaster, blinds.
A realistic room with daylight and pendant lights, 32 parts you can click. Second run (reasoning low): on medium, Opus spent its whole output on thinking and returned no file. No edits.
A dollhouse-style diorama with 17 working parts. One edit: two things were both called "frame", a syntax error that stopped the page; we renamed one (marked in the source). Nothing else touched.
A voxel pagoda
The kind of test the leaked GPT-Next outputs showed: a five-storey pagoda on a floating island, with a time-of-day slider.
Koi pond, torii gate, falling petals, a waterfall into the clouds; at night the lanterns glow and fireflies come out. No edits (the first request died with a provider error and was simply sent again).
Detailed, with a lovely starry night, but the camera starts close and you never see the whole island. Second run (reasoning low): on medium the file was cut off by the 64k output limit. No edits.
A card machine
An isometric SVG card terminal: swipe, PIN, approved, receipt, on a loop.
Card swipe, processing, approved, a curling receipt, a speed slider. No edits.
A keypad that types a PIN, sound waves, a receipt with line items. No edits (reasoning medium, 8 minutes).
