Ruben Hassid

An AI consultant and newsletter author (“How to AI” on Substack) who translates developer-facing AI documentation for general/business audiences. By his own account non-technical — a university dropout who managed a techno music label before AI consulting — which frames his output as accessible advice rather than primary/benchmark reporting. In this spoke he wrote “Don’t use Claude Fable 5”, a buyer’s-guide take on Fable 5 pricing, model choice, and prompting. Treat his claims as T3 practitioner opinion.
