# FFT config for Llama 3.2 1B Instruct.
# Borrows param values from:
# https://github.com/pytorch/torchtune/blob/main/recipes/configs/llama3_2/1B_full.yaml
#
# Requirements:
#   - Log into WandB (`wandb login`) or disable `enable_wandb`
#   - Log into HF: `hf auth login`
#   - Request access to Llama 3.2: https://huggingface.co/meta-llama/Llama-3.2-1B-Instruct
#
# Usage:
#   oumi train -c configs/recipes/llama3_2/sft/1b_full/train.yaml
