Many do not give Sonnet or even Opus full reign where it really pushes ahead of over models.
If you're asking for tightly constrained single functions at a time it really doesn't make a huge difference.
I.e. the more vibe you do the better you need the model especially over long running and large contexts. Claude is heading and shoulders above everyone else in that setting.
For sure, but the coolest thing about qwen3.5-plus is the 1mil context length on a $3 coding plan, super neat. But the model isn't really powerful enough to take real advantage of it I've found. Still super neat though!
You may want to look at the AGENTS.md file too so you can include your stock style things if it’s repeatedly screwing up in the same way.
The Pi framework is probably right up your alley btw! Very extensible
