LobeHub

Use AIOHub models through the LobeHub web chat interface, no coding required.

AIOHub provides a web chat interface through LobeHub. After signing up, you can start chatting with AI models in minutes, without writing code.

What is LobeHub

LobeHub is an open-source AI chat platform based on LobeChat. You can treat it as a web chat app where you choose the model provider yourself. AIOHub runs a hosted LobeHub instance at chat.aiohub.org, connected to AIOHub model routes so you do not need to deploy LobeHub yourself.

Conversation history is managed by LobeHub and the browser experience. AIOHub still receives model API requests through the configured provider URLs and records usage logs for billing and troubleshooting.

How is it different from the ChatGPT official site?

Area	ChatGPT official site	AIOHub + LobeHub
Model range	Mainly OpenAI models	Use GPT, Claude, Gemini, and open-source models through AIOHub
Billing	Usually monthly subscription plus limited usage-based options	AIOHub balance-based usage billing; subscription plans are also supported
Data storage	Conversation data is stored on OpenAI servers	Conversation history is stored locally in the browser. Model API requests still pass through AIOHub for billing and logs
Plugins and extensions	Supports GPTs and limited plugins	Open-source plugin ecosystem with knowledge base, TTS, agents, and more
Access	Some regions may need special network access	Direct access without special network access

Who is it for?

• You want to use GPT, Claude, Gemini, and open-source model families from one chat interface.
• You do not want a monthly subscription and prefer usage-based billing with flexible cost control.
• You want a ready-to-use web chat UI instead of writing API code.

Steps

1. Create an AIOHub account

   Open the console, sign up, and log in.

2. Add funds

   AI model calls consume account balance. After logging in, open wallet management to add funds. See Add funds for payment and billing details.

3. Create an API key

   An API key is the credential LobeHub uses to access AI models. AIOHub uses this key to identify your account and deduct usage from your balance or plan. You can view and manage created keys in the console at any time.

   Go to the console Token page and select New token:

   • Name: use any label that helps you identify the key.
   • Group: use auto for quick validation. For long-term use, choose specific groups based on Groups. Recommended examples are claude-kiro for Claude models and codex for OpenAI-compatible models.

   

   After the key is created, copy the generated sk- value.

   
4. Sign up and log in to LobeHub

   Go to https://chat.aiohub.org. Your LobeHub account is separate from your AIOHub account, so you need to register once.

   Click Continue with Auth0 on the page:

   

   On the login page, sign in if you already have an account. If not, choose the sign-up option:

   

   Enter your email and password to complete registration:

   
5. Configure AI providers

   After logging in, enter the LobeHub main screen. Click the avatar in the top-left corner, then choose Settings.

   

   Find AI provider in settings. Configure two providers when you want GPT/OpenAI-compatible models and Claude-compatible models:

   Provider	What it is	Example models
   OpenAI	Provider for GPT-family models	gpt-4o, gpt-5.4, o4-mini, gpt-5.5
   Anthropic	Provider for Claude-family models	claude-sonnet-4, claude-opus-4, claude-haiku-4

   Start with OpenAI:

   

   Fill in the fields below, choose the model you want to use, such as gpt-5.4, and click Check to verify the connection:

   Setting	Value
   API Key	sk-your-api-key
   API Proxy URL	https://api.aiohub.org/v1

   

   Next, go back to the AI provider list, find Anthropic, and configure it the same way. The Anthropic API Proxy URL does not include /v1:

   Setting	Value
   API Key	sk-your-api-key (the same key as OpenAI)
   API Proxy URL	https://api.aiohub.org

   

   OpenAI and Anthropic use different proxy URLs. OpenAI uses https://api.aiohub.org/v1; Anthropic uses https://api.aiohub.org without /v1. Mixing these URLs causes connection failures.

   Available models depend on the groups assigned to your API key. If a model is missing, go back to the AIOHub console and check whether the key group includes that model.
6. Start chatting

   Go back to the main screen, click New Conversation, and choose the configured model from the model dropdown. This example uses gpt-5.4:

   

   Type a message to start the conversation:

   

View usage

After sending a message, open the AIOHub console Logs page to view the calls created by that conversation:

One user message can produce several usage log entries, such as text-embedding-3-small, gpt-5.4-mini, and gpt-5.4. This is normal. LobeHub can call auxiliary models in the background:

• text-embedding-3-small: converts messages into vectors for knowledge base retrieval and context matching.
• gpt-5.4-mini: generates conversation titles and handles other helper tasks.
• gpt-5.4: the main chat model you selected, which answers your message.

These auxiliary calls are usually low cost, but you can reduce unnecessary usage by changing helper model settings in LobeHub. See Understand auxiliary models.

Use lower-cost groups

The guide above uses auto for quick setup. If you want lower cost, create an API key with more economical groups and replace the key in LobeHub.

1. Create an economical API key

   Go back to the AIOHub console Token page. Create a new key and select both codex for OpenAI-compatible routes and claude-kiro for Claude routes. Check Groups for current group ratios.

   

   After creation, the token list shows that this key includes both groups:

   
2. Replace the API key in LobeHub

   Go back to Settings -> AI provider in LobeHub. Replace the OpenAI API Key with the new economical key, then verify it:

   

   Replace the Anthropic API Key with the same new key:

   
3. Verify usage

   Choose a model and start a conversation:

   

   Return to the AIOHub console logs. You can confirm that calls now use the lower-cost group:

   

Understand auxiliary models

You may notice that one message creates multiple usage log entries. This happens because LobeHub can call helper models in addition to the main chat model:

Helper feature	Default model	Purpose
Topic naming	gpt-5.4-mini	Generates a title for new conversations so they are easier to identify in the conversation list
Translation helper	gpt-5.4-mini	Translates UI content or messages when needed
Knowledge base embedding	text-embedding-3-small	Converts messages into vectors for knowledge base retrieval and semantic matching

These auxiliary calls consume AIOHub balance, though each call is usually small because helper models are normally much cheaper than the main model.

See the LobeHub documentation for detailed feature settings.

Open LobeHub and start chatting

Go to the web chat interface.

FAQ

Connection test fails

Make sure the API Proxy URL is https://api.aiohub.org/v1 for OpenAI, and that the API Key starts with sk- and is valid.

Model list is empty or missing a model

Manually type the model name in the model list to add it. If it still does not work, check that the group assigned to your API key includes the model in the console. For example, GPT models need the openai or auto group.

Which group should I pick?

For normal chat, use auto for smart routing or openai for GPT and OpenAI-compatible models. See Groups.

Conversation errors or empty responses

Check that your console balance is sufficient and the API key has not expired. You can also check the Logs page in the console for specific error details.
