# Manage models for GPT for Docs

[Models](https://autosheet.com/docs/resources/guides/concepts#model) are the engines that power GPT for Docs. GPT for Docs supports models from [OpenAI](https://openai.com/) and [Anthropic](https://www.anthropic.com/).

> **Info**
>
> As a space owner or admin, you can control which models are available to users in your space through the [AI configuration section](https://autosheet.com/docs/admin/ai-configuration/manage-models) in the Autosheet dashboard.

Which model is the right one depends on your specific needs in terms of response quality, speed, privacy, and cost. The following table summarizes the kinds of models available in GPT for Docs, from zero setup to more advanced options:
