NextChat
NextChat uses FreeTheAI through its custom OpenAI endpoint. Add the model IDs to Custom Models so they appear in the picker.
Category: Chat apps. Before you start, you need a FreeTheAI account, an API key, and today's check-in.
Settings
| Setting | Value |
|---|---|
| Custom Endpoint | On |
| Model Provider | OpenAI |
| OpenAI Endpoint | https://api.freetheai.org |
| OpenAI API Key | Your FreeTheAI key (ftai_..., 53 characters) |

Steps
Turn on the custom endpoint
Open Settings and turn on Custom Endpoint. Set Model Provider to OpenAI.
Enter the endpoint and key
Set OpenAI Endpoint to api.freetheai.org (NextChat adds /v1/chat/completions) and paste your key.
Add your models
In Custom Models, list the models you want, separated by commas, then pick one in a chat.
Common questions
Why does NextChat call the wrong URL?
Enter the root address api.freetheai.org without /v1. NextChat appends v1/chat/completions itself.
