Hey, thanks for the report. There are two separate things here. First, Claude Sonnet 5 and most third-party models being turned off by default in the model list is expected after a recent change. We reduced the recommended set, and you now need to enable the rest manually. Second, an enabled model not staying enabled after restarting Cursor should not happen, and it’s not related to your settings. Same for non-recommended models that sometimes show up and then disappear from the list. I shared this with the team and we’re tracking it. I can’t share a timeline yet, but I’ll post an update here once I have one. For now, the only workaround is to re-enable the model each time. Let me know if you notice any extra details, like whether it’s tied to specific models or only Sonnet 5. ---

Hey @Evan_Lee, As promised, I’m back with an update. The issue where re-enabled models like Claude Sonnet 5 would become disabled again after restarting Cursor was fixed in one of the recent releases. Models you enable in Settings should now stay enabled across restarts. Please update Cursor to the latest version. That should fix it. Let me know if any model still turns itself off after the update.
