Both models were given identical prompts, MCP servers, and skills to build a habit tracker app from scratch. GPT-5.6 delivered a comparable result at roughly half the cost ($5/$50 vs $10/$50 per million tokens), successfully implementing features like native widgets, haptics, dark mode, and sortable lists. GPT-5.6 edged out on first-try sortable list implementation and UI consistency, while Claude Fable 5 produced slightly better widgets. Both took about an hour to complete. The conclusion is that GPT-5.6 is the better value, delivering near-identical quality at significantly lower cost. ## Full article daily.dev links to this article rather than hosting it.
