273* Cloud sessions, on [Claude Code on the web](/docs/en/claude-code-on-the-web) or in the Desktop app, run on Anthropic-managed VMs by default: settings deployed to your device do not reach them, so deliver the allowlist through server-managed settings. Sessions your organization routes to a [self-hosted environment](/docs/en/self-hosted-environments) run on your own compute and also read the managed settings file in the runner image. [How Claude Code combines managed sources](/docs/en/managed-settings#how-claude-code-combines-managed-sources) says when that file applies. A mid-session model switch in a cloud session is rejected when the requested model is excluded by the allowlist. When the `availableModels` list in your server-managed settings is non-empty, the server rejects a user's request to start a cloud session on a model the list excludes.
273* [Cloud sessions](/docs/en/claude-code-on-the-web), including those you start from the Desktop app, run on Anthropic-managed VMs by default: settings deployed to your device do not reach them, so deliver the allowlist through server-managed settings. Sessions your organization routes to a [self-hosted environment](/docs/en/self-hosted-environments) run on your own compute and also read the managed settings file in the runner image. [How Claude Code combines managed sources](/docs/en/managed-settings#how-claude-code-combines-managed-sources) says when that file applies.

274274* Cowork, the agentic-work tab in the Claude Desktop app, runs its sessions on Claude Code but, by design, does not receive server-managed settings from the claude.ai admin console. A managed settings file applies to Cowork sessions when it is present where the session runs; remote Cowork sessions run on Anthropic-managed VMs, where a device-deployed file is not present.
275275* Sessions on [third-party providers](/docs/en/server-managed-settings#platform-availability) such as Amazon Bedrock, Google Cloud's Agent Platform, Microsoft Foundry, and [Claude Platform on AWS](/docs/en/claude-platform-on-aws) do not receive server-managed settings, so deliver the allowlist through MDM or managed settings files there.
276276* Server-managed delivery also requires the session to authenticate with an [eligible login or key](/docs/en/server-managed-settings#platform-availability). Fleets that generate keys only through an [`apiKeyHelper`](/docs/en/settings-reference#apikeyhelper) script should deliver the allowlist through MDM or managed settings files.

494494* When the flagged category has no fallback model, such as a biology flag on Opus 5, Claude Code doesn't show the prompt and the request ends with the refusal.
495495* If both models flag the same request, you can edit the prompt and retry, or start a new session.
496* On mobile [Claude Code on the web](/docs/en/claude-code-on-the-web) sessions, editing and retrying is not supported. Switch models, or continue the session from a desktop browser or the desktop app.
496* In [cloud sessions](/docs/en/claude-code-on-the-web) on the mobile app, editing and retrying is not supported. Switch models, or continue the session from a desktop browser or the desktop app.
497497* In [non-interactive mode](/docs/en/cli-reference#cli-flags) and SDK integrations that can't show the prompt, a flagged request ends the turn with a refusal instead.
498498* When the fallback target is blocked by [`availableModels`](#restrict-model-selection), Claude Code doesn't show the prompt. The flagged request ends with the refusal, the same as automatic fallback when the target is blocked.
