Can you elaborate on this "Sonnet and Haiku are almost always less capability-per-dollar than open models"?
Much of Claude Code's internal model routing ends up delegating tasks to Sonnet or Haiku, so by intercepting those calls and using open models instead, we often see better performance at a better price.
If geography is important, we can restrict which geos inference takes place in. And if you don't want to use Chinese-trained models, you can use others like Mistral, Neomotron, Google's, or OpenAI's.
