Developer considers switching from Claude Opus 4.7 to open-source Qwen-35B-A3B for local coding tasks on high-end Mac hardware.

A user running Opus 4.7 on an M5 Max with 128GB RAM is evaluating Qwen-35B-A3B as a potential alternative for their daily coding agent.

The developer acknowledges that Opus may have superior complex reasoning capabilities but questions whether Qwen-35B-A3B can handle most practical tasks adequately.

The post seeks community feedback from the LocalLLaMA subreddit on experiences migrating between these two models for coding applications.
