Gemstone-1024x28

Gemstone-1024x28 is part of the Gemstone Suite of Models. A set of models trained with varying widths and depths.

Training

We train using litgpt and AxoNN using AMD MI250X GPUs on 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. As such it is not an instruction model. This model is trained for 350 billion tokens, we upload checkpoints every 2 billion tokens (477 steps).

Using Gemstone-1024x28

The Gemstones are based on the gemma-2b architecture and use modeling_gemma.py to run using the transformers library.

Licence

This model is released under the apache-2.0 licence.
