How did GPT-5.6 change the ambition or scope of what you shipped?

Maker

I built this entire project using OpenAI Codex as my co-developer, running GPT-5.6 Sol on Extra High effort. It was a wild experience. I used plan mode to design the architecture, especially the tricky parts like the secure iframe sandbox and the Brain routing, and then Codex helped me grind through the implementation to ship a working Next.js app fast. For the actual app runtime, I built a custom routing engine for GPT-5.6. Simple questions or straightforward tool builds get routed to Terra because it's fast. But complex planning, independent code reviews, or if a build fails and needs fixing, that gets automatically bumped up to Sol. Basically, Codex helped me build the factory, and GPT-5.6 runs it for the user.

Finance is deeply personal, but personal finance apps aren't. Every budgeting app I've tried forces you into their specific way of thinking about money. If your brain doesn't work that way, the app feels useless. I wanted to build something where the user doesn't have to adjust to the tool, the tool adjusts to the user. Instead of hardcoding a bunch of fixed dashboards, I realized it made more sense to let users just ask for the exact tool they want, based on their own data. Also, data silos are incredibly frustrating. I wanted my spending, income, and portfolio all in one place so I could actually forecast my cash flow. FinDex was built to solve both of these problems: keeping all your financial data under one roof, and letting AI build the perfect interface for you to interact with it.
