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.
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)
cecli.dev
How are you running these? Not locally, I assume?
