No… mostly. They developed their “zero” model, which (they claim) is a from-scratch model. Base models are typically not fine-tuned for particular applications

No… mostly. They developed their “zero” model, which (they claim) is a from-scratch model. Base models are typically not fine-tuned for particular applications (eg chat). They trained their Zero model into a Chat+Reasoning model, which is what is attracting news. They ALSO fine-tuned small Qwen models using their big models as a teacher (distillation technique).
