Summary

A comparison of four AI models (Fable 5, Opus 4.8, GLM 5.2, GPT 5.5) on generating HTML5 canvas physics demos shows Fable 5 outperforms others in quality but costs significantly more per test.

Fable 5 absolutely crushed the HTML5 physics contest, but cost 6x more than Opus 4.8 and 39× more than GLM 5.2 in that test. Test was done on atomic[.]chat, a desktop app that runs LLMs locally. The test asked 4 models to generate self-contained canvas demos with believable motion and collisions. The scenes were not simple animations because every crash needed gravity, force, timing, and contact handling. Outputs: - Fable 5: 62,158 tokens, $3.12 - GPT 5.5: 37,753 tokens, $1.14 - Opus 4.8: 22,280 tokens, $0.56 - GLM 5.2: 36,246 tokens, $0.08

Fable 5 absolutely crushed the HTML5 physics contest, but cost 6x more than Opus 4.8 and 39× more than GLM 5.2 in that test.

Test was done on atomic[.]chat, a desktop app that runs LLMs locally.

The test asked 4 models to generate self-contained canvas demos with believable motion and collisions.

The scenes were not simple animations because every crash needed gravity, force, timing, and contact handling.

Outputs:

  • Fable 5: 62,158 tokens, $3.12
  • GPT 5.5: 37,753 tokens, $1.14
  • Opus 4.8: 22,280 tokens, $0.56
  • GLM 5.2: 36,246 tokens, $0.08
