From scratch pretraining on english only no synthetic data, no code, 3 epochs of 1 gig of data for the ~125M param model.

Test network using [Tensor Product Attention](https://arxiv.org/abs/2501.06425). Other than some alterations to the attention, such as 16 heads insted of 9 and using TPA, this is the same setup as https://huggingface.co/HuggingFaceTB/SmolLM2-135M-Instruct

# Scripts:
- `inference.py` to run the model with some test prompts
- `test_train.py` runs with the exact configurations used to train this model and is the reproduction script. Data is assumed to be in JSONL format with `"text":"example text", "text":"..."`

# Notes:
One of the primary reported benefits for TPA are for inference which are not really being leveraged at all, although you can probably fit a larger bsz than traditional MHA/GQA with this. This did save about 5% on params, that amount should scale much more as the network size increases. The run time is very similar to MHA/GQA at this scale.
