A whale breaching a cel-shaded ocean

From the post

🚨 Fable 5.5 TESTING Part 7 🐋 I asked Claude to make a whale breach a cel-shaded ocean. One prompt. I never touched the code. 🤯 ⏱️ 154 minutes 💸 $17.85 in API costs 🤖 Claude Fable 5.5 Xhigh in Claude Code What it did on its own 👇 💧 Ran a 16.9 million particle fluid sim at 1,200 steps per simulated second 🌊 Built the ocean from 3 FFT wave cascades, then cut it into crisp cel tones 🐋 Modelled the whale in code: 1,094,000 triangles, zero source art 🧠 Worked out the body displaces only ~70 m³, too little for a real slam, so it added the trapped-air blast 🫧 Went underwater: sun shafts, Snell's window, 165,400 bubble records 🔎 Zoomed 2× into its own frames, caught a faint cross-hatch in the spray and re-rendered 🎵 Wrote and synthesised the score and all the sound 📦 31 s · 1080p60 · 1,860 frames · 8 shots

Author’s claim. Posted before Fable 5.2 came out. The author called it Fable 5.5, the name rumors gave the next Fable. We can’t verify which model ran.
