在 atomic.chat（本地 LLM 桌面应用）的 HTML5 物理竞赛中，Fable 5 以 A+ 成绩完成全部三个场景（火车脱轨、汽车空中碰撞、怪物卡车碾压），消耗 62,158 token，成本 $3.12。相比之下，Opus 4.8 消耗 22,280 token/$0.56，GPT 5.5 消耗 37,753 token/$1.14（在怪物卡车场景中略胜 Fable），GLM 5.2 消耗 36,246 token/$0.08 但未赢得任何场景。Fable 5 质量最佳但成本最高。
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 totally crushed our new contest, but it cost 6x more than Opus 4.8! We gave 4 models the same prompt: build three self-contained HTML5 canvas scenes with real physics demos Prompts: — A train derailing off a broken bridge into the water — Two cars jumping off ramps and colliding mid-air over a canyon — A monster truck crushing a row of parked cars 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 did all three scenes at A+. The crashes looked real, things fell and broke the right way, and nothing went through the ground or floated. GPT 5.5 was the closest to Fable. In the Bigfoot show, we think GPT was even a little better. GLM 5.2 did not win any scene, but it was the cheapest by far. Fable is the best pick for quality, but you pay more for it.在 X 查看被引用的帖子
