118118* **Anthropic API or subscription only**: fast mode is available through the Anthropic Console API and for Claude subscription plans using usage credits. It is not available on Amazon Bedrock, Google Cloud's Agent Platform, Microsoft Foundry, or Claude Platform on AWS. Console organizations must also have [fast mode access provisioned](#enable-fast-mode-for-your-organization).
119119* **Usage credits turned on for subscription plans**: on a Pro, Max, Team, or Enterprise plan, your account must have [usage credits](/docs/en/costs#add-usage-credits-to-your-subscription) turned on, which allows billing beyond your plan's included usage. Until they're on, `/fast` reports "Fast mode requires usage credits". How you turn them on depends on your plan:
120120 * On Pro and Max, turn them on in the **Usage credits** section of [**Settings > Usage**](https://claude.ai/settings/usage) on claude.ai, or run `/usage-credits` to open that page.
121 * On Team and Enterprise, a member with billing access turns them on for the organization at [**Admin settings > Usage**](https://claude.ai/admin-settings/usage), and a member without it runs `/usage-credits` to send the organization's admins a request.
121 * On Team and Enterprise, a member with billing access turns them on for the organization at [**Organization settings > Usage**](https://claude.ai/admin-settings/usage), and a member without it runs `/usage-credits` to send the organization's admins a request.

123123<Note>
124124 Fast mode usage draws directly from usage credits, even if you have remaining usage on your plan.

143143* **Console** (API customers): an admin enables it in [Claude Code preferences](https://platform.claude.com/claude-code/preferences). Fast mode is in [research preview](#research-preview), so your organization must also have fast mode access provisioned before fast mode requests succeed. To get access, contact your account manager or join the waitlist, as described in [fast mode on the Claude API](https://platform.claude.com/docs/en/build-with-claude/fast-mode).

145145 Without provisioned access, the API rejects each fast mode request with a 429, and Claude Code treats each rejection as a [fast mode rate limit](#handle-rate-limits). Unlike a rate limit's cooldown, the rejections continue until access is provisioned.
146* **Claude AI** (Team and Enterprise): an Owner enables it at [Admin Settings > Claude Code](https://claude.ai/admin-settings/claude-code)
146* **Claude AI** (Team and Enterprise): an Owner enables it at [**Organization settings > Claude Code**](https://claude.ai/admin-settings/claude-code)
