About

This repository contains the xLSTM checkpoints of the token/param scaling law configuration from our xLSTM scaling law analysis.

Using the checkpoint collection

To run inference with our scaling law checkpoints, we use the huggingface transformers xLSTM-7B implementation.

We refer to the Readme.md of our xLSTM scaling law github repository for more details.
