Chatbox is a desktop AI client that supports the OpenAI-compatible interface; connect it to this service through the "OpenAI API Compatible" mode.

Open the settings

Click the Settings icon in the left sidebar and go to the Model tab.

Select the AI provider

Choose OpenAI API Compatible in the Model Provider dropdown.

Fill in the following fields:

Field	Value
API Key	Your `codex_...` or `sk-...` key
API Host	`https://aicentos.com`
Model	`gpt-5-codex-mini` or another available model

Note: the Chatbox API Host field only takes the service root address — do not add the /v1 suffix. Example: https://aicentos.com

After saving, start a conversation and confirm it returns normally.

Enter the service root path without /v1 in the API Host field; Chatbox appends the API path automatically
Available models are determined by the list returned by GET /v1/models
