Choosing the Right AI Tools for Account Scoring and Research

One of my use cases for Clay is to score and tier my list of 2,000 accounts. I likely need 3 columns requiring AI usage (two for advanced web research, one for basic AI usage). Im thinking about using Argon for the advanced research and Helium for basic, but I’ve heard that using an OpenAPI key can be less expensive overall. Any insight on how this might work in terms of cost, and if using OpenAPI keys, is the process much more complicated?
