Chatbox is a cross-platform AI chat client with custom model providers. Use AIOHub through Chatbox’s OpenAI-compatible provider mode. Chatbox is especially useful for using the AIOHub API on mobile devices. If you want to chat with your own AIOHub API key on iOS, Android, or a tablet, Chatbox is usually more direct than developer-tool clients.

​
Prerequisites

  • Chatbox installed, or access to the Chatbox web or mobile app
  • An AIOHub API key
  • A group assigned to the API key that can access the Chat Completions model you want to use
  • A positive account balance

​
Setup

1

Open model provider settings

Open Chatbox, click the settings entry in the sidebar, then open Model Provider.
2

Add a custom provider

Click Add or Add Custom Provider at the bottom of the provider list:
FieldValue
NameAIOHub
API ModeOpenAI API Compatible
3

Enter API settings

Fill in the fields used by your Chatbox version:
FieldValue
API Keysk-your-api-key
API Hosthttps://api.aiohub.org
API Path/v1/chat/completions
If your Chatbox version labels the field as Base URL and expects /v1 there, use https://api.aiohub.org/v1 and keep API Path as /chat/completions. Do not put /v1 in both fields.

Add models

Add or enable the models you want to use:
ModelGood for
gpt-4oEveryday chat, writing, translation
gpt-4o-miniLightweight and lower-cost chat
claude-sonnet-4-20250514Long-form analysis and complex writing
Available models depend on the group assigned to your API key. Use the console model list and /v1/models response as the source of truth.
5

Check the connection

Save the provider, then click Check. If the check succeeds, return to the chat page and select the configured model.
6

Start chatting

Create a new conversation and send a short message. You can then open the AIOHub console Logs page to review the request and cost.

​
Optional settings

  • If automatic chat title generation creates extra requests, disable it in Chatbox settings or use a cheaper helper model.
  • Vision, tool use, and image features depend on the Chatbox version, model capabilities, and the group assigned to the API key.
  • If you only need basic text chat, verify that works before enabling advanced features.

​
Troubleshooting

Confirm the API key starts with sk-, API Host includes https://, and API Path is /v1/chat/completions. If Host already includes /v1, use /chat/completions as the path.
The usual cause is putting /v1 in both API Host and API Path. The full AIOHub request URL should be https://api.aiohub.org/v1/chat/completions.
Check in the AIOHub console that the group assigned to the API key includes that model. You can also request /v1/models to see the models visible to the current API key.
Yes, when the model is available through the OpenAI Chat Completions-compatible path and visible to your API key. For native Claude Messages behavior, use a client with an Anthropic provider or Claude Cowork 3P.
