Opus 5.5 vs Kimi K3: stretchy slime goldfish animation test
Given the same taffy-pull goldfish brief, Opus 5.5 took 40 minutes and $5.70 to get snapping motion, while Kimi K3 finished in 2 minutes for 24 cents but the fish melted flat.
Both models named their slime goldfish after taffy. Claude Opus 5.5 went with Glossfin Taffy, Kimi K3 with Taffy Fins. Opus ran 40 minutes and cost $5.70. Kimi built its page in 2 minutes for 24 cents - about 24x cheaper. The brief: four neon slime goldfish you grab and pull like taffy. Let go and they snap back. At 0:00 the Kimi fish are four glowing balls with fan tails. By 0:01 they have melted into flat puddles, eyes lying next to them. The cursor pulls three times and lifts only a thin thread. The Stretch counter sits at ×1.0 the whole video. Up top, the orange fish stretches into a long ribbon and snaps back at 0:04. Kimi even wrote "pull one and watch it snap back" on its page. Nothing on its side ever snaps back. https://x.com/buzzhive_ai/status/2113417898165178525
