Difficulties advocating Groq

I’m supporting Groq in a WordPress plugin (among the usual suspects: OpenAI, xAI, DeepSeek, etc.) and I want to promote it, but I feel I have to explain the free-tier rate limiting to users. I think this could lead to the perception that Groq is inferior or involves extra hassle to set up when the opposite is the case, effectively penalizing Groq for offering a free tier instead of showcasing it as a selling point.

To clarify, the primary use of the plugin can be supported by a free-tier account, but certain advanced features cannot. Currently, I do not permit users with a Groq key to access advanced features, not only because they would fail before completion for free-tier users, but also because they would disable the primary use of the plugin by hitting the rate limit.

If there were a way to distinguish between free/paid accounts (e.g., based on the user’s API key) I could avoid this. Please let me know.
