Llama-3.2-non-recurrent-posttrained

Llama-3.2-non-recurrent-posttrained is a non-recurrent meta-llama/Llama-3.2-1B based baseline for the Retrofitting Recurrence set of models. A set of depth recurrent models trained by taking layers from pretrained feedforward language models (link to paper).

Training

We train using https://github.com/mcleish7/retrofitting-recurrence using AMD MI300A GPUs on Tuolumne at Lawrence Livermore National Laboratory.

Data

Train and validation data is taken from non-overlapping subsets of raw text data. As such it is not an instruction model.

Licence

This model is released under the apache-2.0 licence.
