PKaI-Nano-1

PKaI Nano 1

PKaI Nano 1 is a 120M-class base language model from PowderKeg Intelligence. It is a compact LLaMA-style decoder model trained from scratch with a Mistral tokenizer and released as a PKaI-native artifact.

This repository contains PKaI-native weights and metadata, not a drop-in transformers.AutoModelForCausalLM package.
