A: Hi!

15.000 messages per month on Tier 1 means how many AI responses you can generate per month using your own OpenAI API Key.

Even when you bring your API key, there are still limits in place, this is because Tiny Talk is still in between your visitor and OpenAI, providing value added services like chat history and search which requires compute and storage. The limit helps us providing fair usage of our platform for all customers in respect to their tiers.

Let us know if we can answer any other question you might have.
Cheers!
