Day 18: Vibe Coding a Thailand Trip Planner with Claude Fable 5 LIVE

Testing Claude Fable 5 LIVE, Anthropic's brand new Mythos-class model that just dropped. I'm vibe coding a full Thailand itinerary planner from scratch with zero formal coding experience, and Fable 5 is the AI doing the heavy lifting. Project 2 starts NOW. Last project (Thailand Cost Calculator) took me 7 days to build live on stream. This time I'm leveling up: a full trip planner that helps travelers build custom Thailand itineraries, from Bangkok to the islands and everywhere in between, and I'm testing the newest Claude model to do it. Why Fable 5? It's Anthropic's most powerful publicly available model, it's Mythos-class, and free access only runs for a limited window before it moves to credits. So I'm putting it to work while I can. What this app will do: Pick your travel style, budget, and trip length Get a full Thailand itinerary with cities, islands, and transport Island hopping routes built in Day-by-day plans based on your preferences This is project 2 in my vibe coding series where I build real travel tools live as a complete beginner. If you missed project 1, go check it out. If you're new here, jump in. Every stream is a fresh start.
