For lots of use cases you don't want the BEST model, you want the model that gets the job done for as little money as possible.
I disagree, I always reach for the best model when I’m at work. For normal questions I do use the default ChatGPT model.
Fundamentally, people underestimate the marginal increase in utility for marginal increase in “intelligence” as measured in benchmarks. Like I’d pay 5x for a model that has 2 units higher in AA intelligence.
And that's almost always another OpenAI or Anthropic model, which are cheaper and more reasoning-efficient
