同一座天空岛四模型对比：V4.1 Flash 3 美分 4 分钟，Opus 5.5 花 4.91 美元
同题生成天空岛视频：DeepSeek V4.1 Flash 1017 花 3 美分 4 分钟但画面全是浓雾，Gemini 4 Argon 15 美分效果第二好，Opus 5.5 花 4.91 美元跑 39 分钟最好。
3 cents, 15 cents, 34 cents, $4.91. One sky island, four models, one run each. The cheaper three were fast: 3 minutes for Gemini 4 Argon, 4 for DeepSeek V4.1 Flash 1017, 11 for Grok 4.7. Claude Opus 5.5 ran for 39 minutes and cost 182x as much as DeepSeek. At 3 cents the island spends the whole clip in thick fog. The windmill barely shows through. At 15 cents Gemini made a storybook: red-roofed windmill, smoking chimneys, a wide white waterfall, rocks floating in a purple sky. At 34 cents Grok put the village in a giant flower pot, and the waterfall pours out of its bottom. At $4.91 Opus has the most of everything: dense pines, glowing windows, a pond with a little bridge. The most expensive island is the best one. The second best cost 15 cents.
