Llama 3.1 Storm 8B Model Variants:

1. Llama 3.1 Storm 8B: The primary, fine-tuned model.
2. Llama 3.1 Storm 8B FP8 Dynamic: An optimized version utilizing FP8 quantization for reduced memory footprint and storage requirements (approximately 50% reduction).
3. Llama 3.1 Storm 8B GGUF: A GGUF-quantized version compatible with llama.cpp.

The Development Methodology:

The superior performance of Llama 3.1 Storm 8B is a result of a three-pronged approach:

Self-Curation: This involved selecting high-quality training examples from five open-source datasets (The-Tome, agent-data, Magpie-Llama-3.1-Pro-300K-Filtered, openhermes_200k_unfiltered, Llama-3-Magpie-PO-100K-SML) using Llama 3.1 8B Instruct to assess their educational value and difficulty. This resulted in a curated dataset of approximately 975,000 examples.

Targeted Supervised Fine-Tuning: The curated dataset was used to fine-tune the model using the Spectrum method, which accelerates training by focusing on high signal-to-noise ratio layers.

Model Merging: The fine-tuned model was then merged with the Llama Spark model (a Llama 3.1 8B Instruct derivative) using SLERP (Spherical Linear Interpolation) to combine the strengths of both.

Impact of Self-Curation and Model Merging:
