# Select a model for bulk tools in Sheets

[GPT for Sheets – Autosheet](https://autosheet.com/docs/gpt-for-sheets) supports a [range of models](https://autosheet.com/docs/resources/models/ai-providers-and-models) that you can use with the [bulk tools](https://autosheet.com/docs/gpt-for-sheets/bulk-tools). To help you find the model that offers the best balance of accuracy, speed, and cost for your use case, see our [recommended models](https://autosheet.com/docs/resources/models/recommended-models).

The available models depend on:

- **The API keys set for your current space.** Autosheet 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-sheets/setup/manage-models/manage-api-keys).
- **The model settings for your current space.** Space owners and admins can [control which models are available in Autosheet](https://autosheet.com/docs/admin/ai-configuration/manage-models?platform=google).
