Yep, fully satisfied with DS 4.1 Flash or GLM 5.3 Flash. I prefer using one chat at a time, actually thinking through things with it, as opposed to the YOLO run all night multi-agent thing. I mean I’m still okay with subagents if my main thread needs to explore a few options and then report back, but all on the same idea.
How are you running these? Not locally, I assume?
You might enjoy Cecli, the successor to Aider. It's made for the kind of workflow you are describing (full hands off yolo and recursive sub-agents also an option, but not the default)
