I was a Claude hater. Fable 5.2 changed my mind.

With Claire Vo · Monday, November 9, 2026

Host Claire Vo reviews Anthropic's newly released frontier model, Fable 5.2, explaining why it shifted her from being a Claude skeptic into an enthusiastic user. She compares Fable 5.2 to Opus 5.5, detailing its high speed, creative strengths in video animation and 3D rendering, and solid architecture capabilities. Vo also highlights significant drawbacks, particularly in unassisted web design and image generation, while showcasing projects like an animated marketing video, flat-pack assembly from photos, and a custom 3D ambient typewriter.
