A: Hi franzundsissi, great to know that Kua.ai is useful. "Bring your own API key" feature is available from Tier 3 and up. And if you use your own key (meaning no token is used on Kua.ai side), there no limit - you can use AI workflow as many times as you want. One thing to note is that: some workflows use GPT 4, so you will need GPT 4 keys to run them.
