Complete Setup Guide
Get Your OpenAI API Key
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.
- Visit OpenAI's API console
- Sign up or log in to your account
- Navigate to the API keys section
- Generate a new API key (copy it immediately as some providers only show it once)
- Save your API key in a secure password manager or encrypted note
Sometimes, this provider will require you to add a payment method to your account before you can use your API key to chat with AI. So, to avoid any hiccups, make sure you've got a payment method set up and ready to go!
Important: Keep your API key secure and never share it publicly. Store it safely as you'll need it to connect with TypingMind.
Configure TypingMind with OpenAI API Key
Option 1: Use the built-in OpenAI provider (recommended)
The quickest way. TypingMind already has OpenAI set up, so you only need to add your API key.
- Open TypingMind and click "Models" in the left sidebar.
- Search for OpenAI.
- Click the settings (gear) button next to OpenAI.
- Paste your API key and save.
Option 2: Add the model manually
If you can't find the provider or model ID in the official list, you can add the model manually:
Open the Models page
Open TypingMind, click "Models" in the left sidebar, then click "Add custom model" in the top right corner.
Enter the model details
Keep "Create Manually" selected and fill in the model details:
Name:o1-preview via OpenAI(or your preferred name)Model ID:o1-previewContext Length: Enter the model's context window (e.g., 128000 for o1-preview)

In the "Authentication" tab, set the connection details:
API Type:OpenAI Chat Completions APIEndpoint URL:https://api.openai.com/v1/chat/completionsAuthentication Type:API Key via HTTP HeaderHeader Key:AuthorizationHeader Value:Bearer <OPENAI_API_KEY>
Add pricing (optional)
Open the "Pricing" tab and enter the model's input, output, and cache prices per 1M tokens so TypingMind can estimate your usage costs.
Check the capabilities
In the "Capabilities" tab, keep "Auto check capabilities on save" on so TypingMind detects supported features like plugins, image input, and thinking, or enable them manually.
Test and save
Click "Test & Save" to verify the connection and add the model.
