# Gemstone-512x16_lr_ablation
Gemstone-512x16_lr_ablation is part of the [Gemstone Suite of Models](https://huggingface.co/collections/tomg-group-umd/gemstone-models-679408ee3f19f1d4d00e8b10). A set of models trained with varying widths and depths. This particular version, denoted by the `_lr_ablation` postfix, corresponds to an ablation detailed in the paper where we train the same suite of models but with a learning rate that is half of the original.

## Training
We train using [litgpt](https://github.com/Lightning-AI/litgpt) and [AxoNN](https://github.com/axonn-ai/litgpt) using AMD MI250X GPUs on [Frontier](https://www.olcf.ornl.gov/olcf-resources/compute-systems/frontier/) at Oak Ridge National Laboratory with a global batch size of 2048.

## Data
Train and validation data is taken from non-overlapping subsets of [dolma](https://huggingface.co/datasets/allenai/dolma). As such it is _not_ an instruction model.
This model is trained for 100 billion tokens (in contrast to the main suite, which is trained to 350 billion tokens), we upload checkpoints every 2 billion tokens (477 steps).

## Using Gemstone-512x16_lr_ablation
The Gemstones are based on the [gemma-2b](https://huggingface.co/google/gemma-2b) architecture and use [modeling_gemma.py](https://github.com/huggingface/transformers/blob/main/src/transformers/models/gemma/modeling_gemma.py) to run using the transformers library.

## Licence
This model is released under the [apache-2.0](https://choosealicense.com/licenses/apache-2.0/) licence.
