We really shouldn't be even mentioning the OpenAI calls in pricing since we equate Gemini-pro calls and perplexity-70b to GPT-3.5. We need to come up with new categories for the AI calls included in pricing that make more sense.
We also notice that the bigger our users get, the more they want to consider open source models and fine tuning. Open AI will be removed from the pricing description in the next few weeks once we come up with a better way of equating AI costs between models with a credit based system.
