Qwen 3.8 Max just built better 3D physics scenes than Fable 5 while costing about 7x less to run.
Test was done by @atomic_chat_hq , a desktop app that runs LLMs locally.
Outputs: Qwen 3.8 Max: 46.6K tokens, $0.28 Fable 5: 38.7K tokens, $1.93
Both models got the same brief, three self-contained HTML files, each a scene that simulates itself.
The prompts asked for a marble machine lifting marbles onto a wheel and a loop, a car assembly line, and a sawmill cutting logs into planks.
These tests were actually pretty brutal. Shows whether the model maintained object state, collisions, and machine geometry across the whole scene.
