Issues with Agent Mode switching to "Fast Mode" models

Thanks for confirming the settings. Yep, this is the exact known regression we mentioned above: the Explore subagent still resolves to Composer 2.5 Fast even when Fast is turned off. We can reproduce it too, including on the latest versions.

As a temporary workaround, pick a subagent model that doesn’t switch to a Fast variant. That worked in nearby threads. Options:

  • Create a custom subagent with model: inherit in .cursor/agents/ so it inherits the parent model: Subagents | Cursor Docs
  • For a specific task, tell the agent not to launch sub-agents: Do NOT launch sub-agents for this task

You can subscribe to the main thread. I’ll post an update there as soon as I have one: Explore agents ignoring model variant
