Eric Siu explains when to use your best AI models. Deploy frontier models like Fable and ChatGPT for planning, strategy, and app development. Save cheaper models for routine tasks as open-weight options get stronger.
When you're working on planning work or when you're working on strategic work, you want to be using the best models out there. It could be a Fable model, it can be a SOL model from ChatGPT, but you want to be using one of the frontier models. Okay, so let's say you're planning something out. Let's say you're building an app. Let's say you are planning out strategy. Maybe you're planning out something around financials, you're planning out something around marketing, business strategy, whatever it is exactly. You want to use the frontier models because those are the smartest for planning. And then you can use something like a lower tier model, like a, you know, Opus 4.8, or you can use like a regular lower version of ChatGPT, maybe 5.5, or you can use the open weight model because open weight models are getting really, really strong now.
