General purpose

We wrote about the implications of the model in a separate post. Aside from that, the model is different from other models and cannot be a drop-in replacement for Llama or Qwen in typical pipelines. It can be used as a substitute for o4-mini-like tasks when given appropriate tools - a reasoning engine with limited world knowledge. While the scores suggest a strong multilingual model, it fell short in our usage, with others on social media reporting similar experiences.
