Introducing message credits, a new default model, and new pricing plans

As you already know, we used to calculate chatbot usage limits using tokens. However, since this is a quite complicated metric, it wasn't easy for most non-technical people to understand. Mevo is not for technical people; it is for everyone who wants to build a chatbot, so we decided to replace tokens with message credits.

How was the conversion done?

After many complicated calculations, including the average token size per message in Mevo's database and the average input and output token spending per conversation, we found the perfect value for the equivalent of 1M tokens and 1500 messages.

It will count user and AI responses as single message credits; some messages longer than the average word count can spend multiple credits. We'll also work on some features so that you can easily see all the credit spending in a conversation.

New default model, GPT-4o-mini

Another important topic is the default model. We were using GPT-3.5-turbo as a default model from the beginning. However, there are more powerful and accessible models now. They have more input and output token limits and better benchmark values compared to GPT-3.5-turbo, which is a relatively old model.

Newly created AI chatbots will use GPT-4o-mini starting today. In the upcoming days, we'll also automatically migrate all chatbots to GPT-4o-mini from GPT-3.5-turbo. If you use another model, you should not do anything; this change will only affect chatbots using the default model.

New pricing plans

We're also introducing three new subscription plans. You can check and see the details from our upgrade window, which you can access within the Mevo dashboard. Our landing page also will be updated soon.
