Fable 5.2 and other four models tested on the same question Fable
Fable 5.2 and other four models tested on the same question Fable: less than 6 minutes, weekly quota 6% Opus: about 5 minutes Sol: 1 minute 53 seconds Astra: 2 minutes 01 seconds Fable's fire is the word burning, and fly is the word spelled out by a thousand birds; Opus is the same style, with less details. Sol is the most elegant, burned into piles of fallen leaves by fire; Astra is left with only particles.

I have the script, editing, songs, and even the 3D footage created. I feel like it might be possible to do it with Opus 5.5 though. tools Editing: Claude Fable 5.2 / Voice: Gemini TTS / Avatar: LTX 2.3 / Image: GPT Image /
