Qwen might be useful to bring out for a second opinion on some more focused details that are largely information complete. Like, use Glimmer to bring together all the relevant critical data and evaluate what the actual problems are, then maybe prototype a solution. If it's still acting up, maybe throw the resulting context at Qwen and let it meditate on it.
I think there was some study done where ideally you would want to throw a bunch of different models at a problem since they don't all have the same perspective or diagnosis on what the problems or the solutions are.
From my testing so far, Qwen 3.8 is better at code but it tends to meander and take forever if it has to look in a lot of places. Glimmer will use like ~1k tokens to formulate a plan and Qwen 3.8 will routinely go over 10k
LM Studio isn't exposing a dropdown for this, at least with the unsloth build.
Unsloth Studio / Desktop does.
For some usages that speedup more than makes up for it being inferior to Qwen intelligence wise.
