Claude Fable 5 is BACK

Synopsis

Solo episode on tactical Fable 5 use cases: an Anthropic employee uses Fable to cut a launch video from 17 takes across four scenes (transcribe, subagent picks best shots, FFmpeg stitch, color grade); Greg runs tournaments for copy and landing pages scored by AI judge panels, an interview-before-build prompt that pushes back on the spec, prompts for negotiation, contract review, second-brain digests and 'find the gaps worth filling', and closes with three startup ideas — synthetic focus-group firm, 48-hour custom software, contract refund firm — plus the prompts behind each.
