I have to get my own api right? And then I choose the models right?

I want to get the exact output as I do when i use perplexity.ai free model. So I'm wondering which model that would be and if I'd get the exact same output?

I asked perplexity.ai this exact question (as in the perplexity chat) and it said:

"If you want to get the same results as when using the free version of Perplexity.ai, you should use the pplx-api with the pplx-default model. This will give you access to the same model that powers the free Perplexity.ai experience."

However, I couldn't find much info about the pplx-deffault model so I"m not sure if that answer is true. Thanks
