# CoLMLM-360M-FW

The 360M-parameter, SmolLM2-based **Co-LMLM** retriever from the paper
[**Co-LMLM: Continuous-Query Limited Memory Language Models**](https://arxiv.org/abs/2607.07707),
trained on FineWeb-Edu.

Co-LMLM is a retrieval-aware language model: at each `<FACT>` position it emits a continuous query
from its hidden state that retrieves the fact's content from an external index at inference time,
instead of storing it in its weights.

## Usage

The model is used together with a released retrieval index. See the code repository for setup,
index downloads, and a copy-pasteable quick start:

This model is part of the [**Co-LMLM** collection](https://huggingface.co/collections/lil-lab/co-lmlm-6a4e8216d55eae83af348f57).
