Language model

BarunLM is a 35M-parameter decoder-only base model, built to study how architecture, data quality and evaluation interact under hard compute limits. Twelve layers repeat three local-attention blocks and one global one. It is a measuring instrument, not a chatbot.

Purpose

A measuring instrument, not a chatbot.

BarunLM is an English-centric base completion model. It is designed for architecture research, controlled evaluation, and local experimentation rather than instruction-following chat.

Design

Local attention, then global context.

The twelve-layer network repeats a three-local, one-global attention pattern. This creates a useful laboratory for studying efficiency and information flow.

Release standard

Evidence travels with the artifact.

Weights, configuration, evaluation details, limitations, and usage guidance are treated as one release surface.
