Haiku 5.5 vs Sonnet 5.5: same 3D animation task, 11 min vs 33 min, bugs reported
iamfakhrealam · x · 2026-10-08
iamfakhrealam reshares rubenssotoai's head-to-head test of Haiku 5.5 vs Sonnet 5.5: the same prompt asked both models to build a cinematic 3D animation explaining how a Tesla-style electric motor works. Haiku 5.5 finished in 11m 13s while Sonnet 5.5 took 33m 3s — roughly 3x slower — though repliers claim Haiku's output has some bugs. A useful hands-on data point on the speed/quality tradeoff between Anthropic's latest models.
