2525The same request works in a one-to-one direct message, where it applies to that conversation only. In a group DM, the switch applies to the thread you ask in.

35Claude sets the channel's default model. New threads in the channel start on it. A thread already underway switches to it at the next message anyone posts there, unless someone in that thread has already had Claude switch models. If an admin has set the scope's **Channel member edits** setting to **Block**, Claude declines to set the channel default; ask for the thread alone instead.
37Claude sets the channel's default model. New threads in the channel start on it. If you asked for a family rather than a version, the default keeps following that family: when your organization gets a newer model in it, new threads start on the newer model without anyone changing the setting. A thread already underway switches to it at the next message anyone posts there, unless someone in that thread has already had Claude switch models. If an admin has set the scope's **Channel member edits** setting to **Block**, Claude declines to set the channel default; ask for the thread alone instead.

3739Admins set the same default from claude.ai, per workspace or channel; see [choose the model for a scope](/docs/claude-tag/admins/customize#choose-the-model-for-a-scope).

41Open the Claude app's **Home** tab in Slack. When model selection is enabled for your organization, the tab includes a model selector for one-to-one direct messages. New direct message conversations you start with Claude use the model you pick there. The selector offers only the models your organization allows.
43Open the Claude app's **Home** tab in Slack. When model selection is enabled for your organization, the tab includes a model selector for one-to-one direct messages. New direct message conversations you start with Claude use the model you pick there. The selector offers only the models your organization allows, and lists each model family as an option such as **Opus (latest)** ahead of the specific versions; with a family option, each new direct message conversation starts on the newest model of that family.

4345The selector doesn't change a conversation already underway. To change one of those, ask Claude to switch in that conversation.
