[P] Discover AstraQuasar-4B: a NEW LLaMA-based arch | First training implementation of the self layer calling (Duplicate Trick)

Hey r/MachineLearning,

I'm reaching out to this incredible community because we've got something unique on our hands, and it's a bit of a diamond in the rough. Meet [AstraQuasar-4B](https://huggingface.co/AstraMindAI/AstraQuasar-4B), a fresh take on language models with a twist – it's ambitiously undertrained but holds a secret sauce called the duplicate trick (also rocking in backprop!).

AstraQuasar-4B is built on the robust Phi-2 architecture, yet it's not your run-of-the-mill model. The duplicate trick is its standout feature, significantly reducing loss with …
