 - **CAIS** for the **MMLU** dataset used for auxiliary knowledge and reasoning supervision.
 - **HuggingFaceTB** for the **OpenHermes-2.5-H4** dataset used in the final instruction refinement phase.
 - **Weights & Biases (W&B)** for logging and visualization tools used to monitor training progress.
+- Additionally, we drew valuable insights from **The Smol Training Playbook: The Secrets to Building World-Class LLMs**, published by Hugging Face, which informed several practical decisions in our training and experimentation workflow.
