Three arcade classics in 3D — Kimi K3 vs Claude Fable 5
Three one-line briefs — a Pac-Man maze with four hunting ghosts, Nokia Snake in 3D, a retro space pinball table — handed to an open-weight model running on the author's own GPUs and to the strongest cloud model of the moment. Kimi K3 spent roughly 237K tokens on the set, Fable 5 spent 92K. Both shipped all six playable scenes; the clips below are the Pac-Man maze, one half of the author's split screen each.
"Three arcade classics in 3D — Kimi K3 vs Claude Fable 5" is one prompt run by 2 models: Kimi K3 and Fable 5. 2 of 2 finished, on figures reported by the author.

Figures reported by Atomic Agent. Not independently verified.
Numbers on this page were reported by the author. We did not run this comparison and cannot verify them.
Token counts are the author's own figures, published in the post and burnt live into the video; we did not run this and cannot reconcile them against a harness log, and the Kimi figure is given as an approximation. The prompt above is not verbatim — the author published three one-line briefs, not the exact string sent to each model, which is why no hash is recorded. No cost is recorded here: the author states $0 for Kimi because the run was on his own 8x B300 GPUs, and a zero on this site would read as 'this model was free'; he gives $3.60 as the Moonshot API equivalent and $4.50 for Fable 5, neither of which we can verify. Read the post knowing who wrote it: Atomic Agent sells the local-model runner the open-weight side of this comparison runs on, so the test is a vendor's own. Its build is still the author's, and the video shows both artefacts rather than a claim about them. A repost of it by @testingcatalog carries a paid-partnership label; the post credited here does not.
