This is Fujii. In this article, I will explain how to use your own API key in Afforai.

I got a question on YouTube.

It says "Bring Your Own Key via OpenRouter (GPT4, Claude, Sonnet, Gemini, etc)" but I don't know how to set it up. I would appreciate it if you could explain it to me.

Normal use of Afforai does not require BYOK settings. If you wish to set up your own, please continue reading below.

This article first explains BYOK. Then,

What is Bring Your Own Key (BYOK)?

First, the acronym for Bring Your Own Key.BYOKIt is.

Afforai's chat function is unlimited.

*There is a fair use policy, though, so you may be banned if you use the service in a way that breaks the service.

But what if you want to use an AI model that is not supported by Afforai?

That is BYOK. Use your own API key,That's what I mean.

You can use the encrypted OpenRouter API key (rest assured that the API key is not viewed by Afforai's management).

Tips for setting up BYOK in Afforai

Afforai can use its own API key. This option is not necessary for normal users, but by connecting the API key with BYOK, you can use AI models that are not normally available in Afforai.

Here is some advice before you set it up. The following advice from Afforai is pasted below.

• Initially, start with the Afforai selection to understand how to use the keys.
• If you want to choose your own model, we recommend that you change only the Query Model and leave the others as GPT-3.5.
• If you want to customize the model significantly, choose the cheapest option possible for each model, and gradually increase the performance of the model to find the cosmetics that are best suited to your needs.

Note: It is strongly recommended to select a model with at least 16,000 tokens in the context window. This will help maintain AI performance.

Selecting a model with less than 16,000 tokens will degrade the quality of the AI output and may not generate citations.

We hope this will be helpful to those who use BYOK in Afforai.
