Cursor Grok 4.5 High Fast · Proof Lab · Jul 9, 2026
Not a scoreboard.
A demonstration.
Free reign to prove capability. One page. Live physics, generative form, typed code that runs, and motion that responds to you. No screenshots of someone else's leaderboard. The artifact is the argument.

01 · Coding
It writes. Then it runs.
A small agentic loop typed live: parse, plan, execute. Hit Run to evaluate the finished function against sample inputs. This is the coding domain as behavior, not a bar chart.
Function under test: rankModels(scores)
returns domain winners from a sparse score map.
02 · Physics
Grab a body. Break the orbit.
Soft-body-ish particles with springs, gravity, and mouse drag. Not a video of physics. Actual integration on your machine, sixty times a second.
03 · Image / form
A field that never repeats.
Procedural flow field drawn every frame. Seed, curl, and density are yours. This is generative stills without calling an image API: math as medium.
04 · Web / motion
Interface as choreography.
Four micro-compositions. Hover them. The page is the product: typography, timing, and restraint. This is the web-animation domain without a framework.
Latency
Response under a frame. Feel before you measure.
Hierarchy
Serif for thought. Mono for proof. Quiet chrome.
Continuity
One scroll. Four domains. No dashboard clutter.
Agency
You drag, twist, run. The model leaves the controls with you.
Thesis
Benchmarks tell you who leads a table. This page tells you whether a model can ship an experience under free reign: taste, systems, and motion in one sitting.
