Claude Fable 5.2 is now live in fal Agent, turning a game you describe into one you can play.

Describe the game you want, and fal Agent generates the assets and writes the code. You then play the result right beside the chat. The agent also picks the right model on fal and writes the prompts itself.

fal shared two sample games, Skyfarer and Autumn Wind, as public chats where you can follow every step. Each one opens by asking for a gameplay video, then has the agent turn that video into a playable browser game built with Three.js.

fal Agent runs on fal credits. You can pay as you go or pick a monthly plan from $50, and plan credits roll over each month. The $200 Pro and $1,000 Max plans take 5% and 10% off fal Agent credits.
