Ethan Mollick (@emollick.bsky.social): I had Fable build another thing I always wanted, a full procedural fantasy kingdom generator with economics, trade routes, population growth, wars, lineages, and occasional dragons. First, I worked wi

AI researcher Ethan Mollick collaborated with Fable to create The Annals, a procedural fantasy kingdom generator that simulates economics, trade routes, population dynamics, wars, and royal lineages using AI. Users can manipulate various world parameters and trigger events like plagues, dragon attacks, or royal marriages, with the system maintaining a persistent chronicle of all actions. This demonstrates how AI can create complex, interactive world-building simulations for storytelling and gaming applications.

Simon Willison (@simonwillison.net): Somewhat humbling to have Claude Fable do a final review of some software that you're about to release and have it then find (and fix) FIVE release blockers, for an estimated (unsubsidized) cost of $1

Developer Simon Willison used Claude Fable (a coding agent) to conduct a final review of sqlite-utils 4.0rc2 before release, where the AI identified and fixed five release-blocking bugs, including a serious data loss bug in transaction handling. The entire review and fix process cost an estimated $1 in unsubsidized API usage. This case demonstrates how AI coding agents can be used for comprehensive pre-release quality assurance at minimal cost.
