PKaI-Nano-1.1

PKaI Nano 1.1

PKaI Nano 1.1 is a 200M-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.

📖 For the full writeup, benchmarks, and evaluation details, see the announcement post: Introducing PKaI Nano 1.1: A Stronger From-Scratch Model.
