Obtain your OpenAI API key:

1. Sign up for an OpenAI enterprise account:
   • Go to the OpenAI Developer Platform at https://platform.openai.com.
   • Sign up for an account or log in if you already have one.
   • NOTE: This OpenAI enterprise account is not the same as a ChatGPT account. Even if you already have a paid subscription to ChatGPT, you will still need to create and set up an enterprise account as described below.
2. Access the OpenAI settings:
   • Once logged in, navigate to the “Settings” section of your OpenAI account. At the time of preparing these instructions, the “Settings” icon is shaped like a gear and is located in the top-right corner of the screen.
3. Add billing information:
   • OpenAI provides a small initial credit (e.g., $5), which can be used with some basic models to process a small amount of data. However, to get continuous use and to have access to the latest models, you’ll need to put some money (e.g., $5-10) into your account.
   • Therefore, we recommend you enter your billing information by going to “Billing” to enter your desired payment method.
   • OPTIONAL 1: Set up an auto-recharge option to automatically top up your balance (e.g., when it drops below $5, add $25).
   • OPTIONAL 2: Set a usage limit to control monthly spending (e.g., $10/month).
   • NOTE: Your OpenAI balance will expire after a year of non-use. If you’re not sure how much data you will use, start with a small balance, even as low as $5-10.
4. Create an API key:
   • After logging in to your account, click on “Dashboard” in the top menu.
   • Next, click “API keys” in the left menu.
   • Making sure the text at the top-left of the screen says “Default project”, click the “Create New Secret Key” button.
   • Name the API key (e.g., “Test Key”).
   • Click “Create secret key.”
   • Upon generation, copy the API key immediately. It will not be displayed again after you close the window. Keep the API key on your Windows clipboard or paste it temporarily into a text editor to be ready for the next step.
   • NOTE 1: Even though you can never access an API key a second time, you can still regenerate new ones as often as you want.
   • NOTE 2: The OpenAI API key interface supports advanced API key management on a project basis. However, the simple instructions here bypass the complex project-based API approach and should be adequate for most users.

Enter your OpenAI API key into CotranslatorAI:

1. Open the Options window:
   • If prompted, enter your OpenAI API key into CotranslatorAI by following the on-screen directions.
   • Alternatively, navigate manually in CotranslatorAI to the Options window: “Tools” > “Options”.
2. Enter your API key:
   • In the “OpenAI API” tab, click “View/Update”
   • Paste your API key into the pop-up window and click “OK”.
3. Select the AI model:
   • Choose the default model to use.
   • Click “Save” to apply the model choice.
   • NOTE: If you haven’t yet put any money into your OpenAI enterprise account, then you should select the recommended model; some of the others may not work.
4. Verify the API setup:
   • Test the setup by entering a prompt to verify that it works. If you get a response, the setup was successful and you can begin using the AI immediately in CotranslatorAI.
