# Select a model in GPT for Word

[GPT for Word](https://autosheet.com/docs/gpt-for-word) supports a [range of models](https://autosheet.com/docs/resources/models/ai-providers-and-models) that you can use with your AI work in Word.

The available models depend on:

- **The API keys set for your current space.** GPT for Word gives you access to a default set of built-in models. To access additional models, [set an API key for one or more AI providers](https://autosheet.com/docs/gpt-for-word/setup/manage-models/manage-api-keys).
- **The API endpoints set up for your current space.** To access even more models, set up a connection to an [Azure OpenAI API endpoint](https://autosheet.com/docs/gpt-for-word/setup/manage-models/connect-to-azure-openai) or any [OpenAI-compatible API endpoint](https://autosheet.com/docs/gpt-for-word/setup/manage-models/connect-to-api-endpoints).
- **The model settings for your current space.** Space owners and admins can [control which models are available in GPT for Word](https://autosheet.com/docs/admin/ai-configuration/manage-models?platform=microsoft).
