I been using open models for 100% of my coding. 1/2 of the time I'm using local open models like qwen 3.6 or Dwarfstar if it's sensitive code I don't want the internet learning from.

I don't miss using frontier models at all. GLM5.2 and Deepseek V4 pro are both equal or beats sonnet. I haven't had to use Opus for awhile now.
