# About default availability of Copilot models

A policy controls whether unconfigured models default to enabled or disabled.

For enterprises with Copilot Business or Copilot Enterprise plans, the **Default availability for released models** policy controls whether unconfigured generally available (GA) models default to enabled or disabled. If this policy is enabled, users benefit from the latest models without the need for administrator intervention.

## Which models follow the policy?

默认策略适用于未显式配置的模型。 这些模型在贵企业或组织的模型设置中标记为 **“委托给默认策略”**。 当新模型发布时，它会继承默认设置，除非你明确对其进行配置。

以下模型**不**在范围内。 默认情况下，无论“默认可用性”策略设置如何，它们都会被禁用。

* 正式发布前的模型
* 开放式重量模型 （DeepSeek， Kimi K2.7 Code， Kimi K3）
* 数据保留协议未涵盖 GitHub的模型 （Claude Fable 5， Claude Fable 5.1）
* 对于已将模型限制为数据驻留模型或符合 FedRAMP 要求的模型的企业，任何不遵循这些策略的模型

## How do I prevent default enablement?

To disable default enablement entirely, disable the **Default availability for released models** policy in your enterprise or organization's models policies. You can set a policy for the entire enterprise, or disable the policy only in organizations with stricter compliance requirements.

If you keep the **Default availability for released models** policy enabled, you can explicitly disable individual models so that they are not eligible for automatic enablement.

## How do I prepare for new models?

We recommend keeping up with new model releases so you can choose your enablement settings for each one. New models are announced on GitHub's changelog.
