+# 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](https://huggingface.co/oopere)
+
+These models are part of the study "[Exploring GLU Expansion Ratios: Structured Pruning in Llama-3.2 Models](https://doi.org/10.31219/osf.io/qgxea)". 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.

+
+### Performance on Standard Benchmarks
+
+| Benchmark | Original Model | Pruned Model | Relative Change |
+| ---- | ---- | ---- | ---- |
+| ARC-Easy | 65.19% | 40.19% | -38.7% |
+| BoolQ | 64.16% | 62.11% | -3.2% |
+| LAMBADA-OpenAI | 62.20% | 29.85% | -52.0% |
+| LAMBADA-Standard | 53.46% | 24.78% | -53.6% |
+
+### Key Findings
+- Remarkably maintains strong performance on binary classification tasks (BoolQ)
+- Significant degradation on reasoning tasks (ARC-Easy)
+- Substantial impact on long-range comprehension (LAMBADA)
+- Notable increase in perplexity for language modeling tasks
+
+### Limitations
+- Considerable reduction in performance on complex language understanding tasks
+- Significant degradation in long-range dependency handling
+- May not be suitable for applications requiring high accuracy on language completion tasks
+- Best suited for simpler classification tasks
