**Note: internal model, not ready for use**

This is an intermediate model used as base-model for further pythia 12b SFT-8 experiments. 
It was trained on a wider set of instruction-tuning datasets for >12.5k steps with batch-size 128 and a context size of 2048.
The gpt4all dataset had "as a language model" *contamination* (>1.8k entries). We added filtering later, but this model (pre-v8) was trained on the raw unfildered gpt4all dataset.
