Model Card for oopere/pruned40-llama-1b

<!-- Provide a quick summary of what the model is/does. -->

This model is a pruned version of the Llama-3.2 architecture, with a parameter reduction of 40% in the MLP Layers. The pruning process aims to enhance computational efficiency while maintaining acceptable performance across specific tasks. This model is not intended to be used directly, but rather to be fine-tuned for specific tasks where it can achieve equal or superior performance compared to fine-tuning the base model for the same task.

Model Details

• Model Type: Pruned version of LLaMA-1.2B using structured pruning
• Original Model: meta-llama/Llama-3.2-1B
• Pruning Method: Structured pruning of MLP layers using importance scores based on absolute maximum weights
• Size Reduction: 26.3% (from 1.24B to 914M parameters)
• Architecture: Same as original LLaMA but with reduced MLP layer sizes
• Language(s): Same as original model
• License: Same as original model
• Developed by: Pere Martra

These models are part of the study "Exploring GLU Expansion Ratios: Structured Pruning in Llama-3.2 Models". They explore structured pruning in GLU-based architectures using Llama-3.2 (1B and 3B variants). The pruning experiments target optimal expansion ratios to balance performance, computational efficiency, and environmental sustainability. The models were evaluated across multiple benchmarks, including BoolQ, ARC-Easy, and MUSR, and demonstrate significant efficiency gains while maintaining robust task performance.
