What hasn't been shown

  • Runs on the CPU only today. Not eligible to live on a GPU.
  • goinfer can't download it for you: this family only loads from safetensors, which come as several files. That's planned (checkpoint fetch, P1–P9).
  • No vetted checkpoint, so there's no fit verdict, no speed and no tool-calling result for this family.
