What’s the best AI app stack for startups?

Low-code like Bubble with mid-tier models (Sonnet, 4o mini) for most MVPs — ships fast, scales later.

Do I need frontier models like GPT-4o for every AI feature?

No, only complex reasoning or high-stakes accuracy. Mid/lightweight handle 80% cheaper.

Is low-code good enough for production AI apps?

Yes for standard use cases — faster, cheaper. Custom if latency or custom logic demands it.
