GLM-5.3 beat Space Bunny Alpha (the new stealth model launched today) on Newton’s cradle in a 5-scene physics test done by @aimlapi .
Space Bunny Alpha is currently stealth, launched on OpenRouter/OpenCode, with a 1-mn token context window, native multimodal input, strong coding performance.
The tornado and water drop were even harder. Neither model handled those well.
visual result is constrained by the dynamics. you can’t compensate for incorrect collision timing or momentum transfer by adding more detail to the environment.
AI/ML API (@aimlapi): Space Bunny performs TERRIBLE in physics 💀
we tested Space Bunny against GLM 5.3 in a task with a single focus scenes: an explosion in a desert, a tornado, a balloon pop, a water drop fall, and the Newton’s cradle
here’s what we got:
- the Newton’s cradle is where GLM 5.3
