Chatbox API: Add FreeTheAI as a Custom Provider
Chatbox adds FreeTheAI as a custom provider in OpenAI API Compatible mode. It works on desktop, mobile, and the web app.
Steps
Add a provider
Open Settings, then Model Provider, and press Add. Enter the name and choose OpenAI API Compatible.
Enter the connection
Paste your key, the API Host, and keep the API Path as /chat/completions. The preview should show https://api.freetheai.org/v1/chat/completions.
Add models and check
Fetch the model list or add a model ID by hand, then press Check.

Tips
- Chatbox needs at least one model added before Check works.
Troubleshooting
What should the Chatbox preview URL look like?
https://api.freetheai.org/v1/chat/completions. If it shows /v1 twice, remove it from the API Path.
