Claims
- Qwen 3.8 Max produced higher-quality 3D physics simulations than Fable 5 across three distinct scene types.
- Qwen 3.8 Max cost $0.28 per task using 46.6K tokens versus Fable 5's $1.93 using 38.7K tokens, a roughly 7x price difference.
- Qwen's output demonstrated correct object state management, collision handling, and geometric accuracy that Fable 5's output lacked.
- Fable 5 generated faster, working prototypes but with physics errors such as marbles appearing at the top of a wheel rather than being lifted.
Key quotes
Qwen 3.8 Max beat Fable 5 at building 3D physics scenes for 7x cheaper!
Qwen worked much harder on the details. Its textures and shadows look real. Fable 5 built a fast prototype that works and left it there.
In the marble machine, Fable's marbles show up from nowhere at the top of the wheel. In Qwen's, you can see them go up.
