Gemstone-384x36_lr_ablation is part of the Gemstone Suite of Models. 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 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 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-384x36_lr_ablation
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.
