QWEN3.5-Next-Coder does wonders. It's drawbacks are time to first token is 30 seconds to load the model and OpenCode has an unsolved timeout issue on this load, but otherwise once it's warmed up, it's entirely serviceable.

I've got a AMD395+ with 128GB, so running a ~46GB model gives me about 85k tokens, which gives me easily copy/paste/find/replace behavior; it mocks up new components; it can wire in some functionality, but that's usually at it's limits and requires more debugging.

I've been looking at how to schedule it using systemd to keep a wiki up to date with a long loaded project and breaks the "blank page" issue with extending behaviors in a side project.

I understand some of these larger models can do things faster and smarter, but I don't see how they can implement novel functionality required for the type of app I'm concerned with. If I just wanted to make endless CRUD or TODO apps, I'm betting I could figure out a loop that's mostly hands off.
