To use Chat Notebooks or other LLM-related functionality in Wolfram products, you need to:

• Create an account with a supported chat & generative model service provider,
• Provide your payment information on their platform if necessary,
• Generate an API key on their API platform and
• Save this API key to your Wolfram product.

Please note that the service providers typically charge for each API call.

Creating an account with the service provider

1. Go to the service provider’s website, such as:
   • OpenAI
   • Anthropic
   • GoogleGemini
   • AlephAlpha
   • Cohere
   • DeepSeek
   • Groq
   • MistralAI
   • TogetherAI
2. Follow any indicated steps to create your account.

Setting up your payment information with the service provider

Most providers offer free use of their services within specified limits. Using their services beyond these limits typically requires setting up a billing plan and providing them with your payment information. For details, please consult the providers’ respective pages.

Adding a service provider API key to your Wolfram desktop product

1. Select the menu item File ► New ► Chat-Enabled Notebook to start a chat-enabled notebook.
2. Navigate to the menu item Edit ► Preferences and click AI Settings.
3. Open the LLM Service dropdown and select the service provider with which you have registered.
   
4. Click Connect for model list. The WolframConnector window opens
   
5. Click the red “Go to (service provider)” button, where (service provider) is the service provider you selected.
6. In your service account, create a new API key.
7. Copy the new API key and paste it into the API Key field in the WolframConnector dialog. Choose “Save this connection” if you would like to reuse this key in the future.
   
8. Click the Agree and Continue button.
