A galloping zebra from a Fable 5.2 checkpoint

From the post

This is the best output I got from the Claude Fable 5.5 checkpoint on the zebra galloping. >Fable 5.5 is really very impressive. >Anthropic pls drop it as soon as possible

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.
