You must have different use cases than me.
I find even Deepseek Flash v4 0731 even outperforms Opus for me (at 10x the speed two).
Using Sol, Fable, Kimi 3 and other recent models has been unbelievable for me. I didn’t think we’d get to this level for years.
I’m using them for Ruby, TypeScript and Python. In large existing codebases but also lots of tiny tools.
