First, you'll need to obtain an API key from OpenAI. This key allows you to access their AI models directly and pay only for what you use.

1. Visit OpenAI's API console
2. Sign up or log in to your account
3. Navigate to the API keys section
4. Generate a new API key (copy it immediately as some providers only show it once)
5. Save your API key in a secure password manager or encrypted note

1. Open TypingMind in your browser
2. Click the "Settings" icon (gear symbol)
3. Navigate to "Models" section
4. Click "Add Custom Model"
5. Fill in the model information:
   Name: gpt-4-turbo via OpenAI (or your preferred name)

   Endpoint: https://api.openai.com/v1/chat/completions

   Model ID: gpt-4-turbo

   Context Length: Enter the model's context window (e.g., 128000 for gpt-4-turbo)
   gpt-4-turbohttps://api.openai.com/v1/chat/completionsgpt-4-turbo via OpenAIhttps://www.typingmind.com/model-logo.webp128000
6. Add custom headers by clicking "Add Custom Headers" in the Advanced Settings section:
   Authorization: Bearer <OPENAI_API_KEY>:

   X-Title: typingmind.com

   HTTP-Referer: https://www.typingmind.com
7. Enable "Support Plugins (via OpenAI Functions)" if the model supports the "functions" or "tool_calls" parameter, or enable "Support OpenAI Vision" if the model supports vision.
8. Click "Test" to verify the configuration
9. If you see "Nice, the endpoint is working!", click "Add Model"

Now you can start chatting with GPT-4 Turbo through TypingMind:

• Select GPT-4 Turbo from the model dropdown menu
• Start typing your message in the chat input
