# Baby Llama

Our submission to the `strict-small` track of the [BabyLM challenge](https://babylm.github.io/index.html).

Baby Llama is a 58M-parameter model, distilled from an ensemble consisting of LLaMA-360M and GPT2-705M, both trained on the `babylm_10M` dataset.

See the associated paper (arXiv number **TBA**) for a detailed discussion of the training procedure and of the model performance.
The training code is available at [https://github.com/timinar/BabyLlama](https://github.com/timinar/BabyLlama).

### Hyperparameters for the tasks that require fine-tuning

When evaluating the model on the [tasks that require fine-tuning](https://github.com/babylm/evaluation-pipeline/tree/main#fine-tuning),
we noticed that the [default hyperparameters](https://github.com/babylm/evaluation-pipeline/tree/main#hyperparameters)
suggested by the BabyLM organizers lead to severe overfitting in a number of tasks.
To avoid this issue, we have re-tuned those hyperparameters.
The sets of hyperparameters selected for each task are listed in the table below.
