The Claw-Machine Challenge: Over an Hour of Grinding, a Solid Build, and a Speed Problem

Published Nov 13, 2026 · Last updated Nov 13, 2026

"Generate a playable claw machine from one prompt" is a favourite product-community stress test: it taxes physics simulation, interaction logic and UI polish at once. Woshipm (人人都是产品经理) ran it against Qwen4-Max-Preview on November 12, and the result was a study in contrasts — a painfully slow process that produced a surprisingly solid machine.

The process: 1+ hour at ~33 tokens/second

The build took over an hour, with output measured at roughly 33 tokens per second. For a model running its highest reasoning tier that is not shocking, but as a lived experience — watching a mini-game assemble — it is a long wait. The figure is a single-session anecdote and may reflect entry point and load; still, several independent tests land near the same number (see our Alibaba Cloud developer write-up), so slowness looks like a trait of this preview, not an accident.

The product: all the physics is there

The slow work paid off in the artifact: claw force feedback, rope sway, doll-on-doll collision and a scoring system are all present, and the delivery was judged solid. Multi-subsystem builds like this usually fail halfway — one wrong physics step cascades. Finishing in one pass is real evidence of long-horizon coherence.

The coordinate: "on par with Kimi K3.1"

The tester's lateral verdict was "on par with Kimi K3.1." That is a product reviewer's feel, not a benchmark, but it is a useful anchor: Qwen4-Max-Preview sits on the first-tier domestic flagship line, not above it.

Our take: this challenge captures the model's personality precisely — patient, capable of assembling a complex system end-to-end, and genuinely slow. For "a demoable prototype by end of day" it passes; for rapid-fire iteration, budget the waiting time first.
