Hey Guys,

I am thinking about switching from Opus 4.7 to Qwen-35B-A3B for my daily coding agent driver.

Has anyone done this yet? If so, what has your experience been like?

I would love to hear the communities take on this. I know Opus may have the edge on complex reasoning, but will Qwen-35B-A3B suffice for most tasks?
