# Sparse-Llama-3.1-8B-evolcodealpaca-2of4

## Model Overview
- **Model Architecture:** Llama-3.1-8B
  - **Input:** Text
  - **Output:** Text
- **Model Optimizations:**
  - **Sparsity:** 2:4
- **Release Date:** 11/21/2024
- **Version:** 1.0
- **License(s):** [llama3.1](https://huggingface.co/meta-llama/Meta-Llama-3.1-8B/blob/main/LICENSE)
- **Model Developers:** Neural Magic

This is a code completion AI model obtained by fine-tuning the 2:4 sparse [Sparse-Llama-3.1-8B-2of4](https://huggingface.co/neuralmagic/Sparse-Llama-3.1-8B-2of4) on the [evol-codealpaca-v1](https://huggingface.co/datasets/theblackcat102/evol-codealpaca-v1) dataset.
On the [HumanEval](https://arxiv.org/abs/2107.03374) benchmark, it achieves a pass@1 of 49.1, compared to 48.5 for the fine-tuned dense model [Llama-3.1-8B-evolcodealpaca](https://huggingface.co/neuralmagic/Llama-3.1-8B-evolcodealpaca) — demonstrating over **100% accuracy recovery**.


### Model Optimizations

This inherits the optimizations from its parent, [Sparse-Llama-3.1-8B-2of4](https://huggingface.co/neuralmagic/Sparse-Llama-3.1-8B-2of4).
Namely, all linear operators within transformer blocks were pruned to the 2:4 sparsity pattern: in each group of four weights, two are retained while two are pruned.


## Deployment with vLLM

This model can be deployed efficiently using the [vLLM](https://docs.vllm.ai/en/latest/) backend. vLLM aslo supports OpenAI-compatible serving. See the [documentation](https://docs.vllm.ai/en/latest/) for more details.


## Evaluation

This model was evaluated on Neural Magic's fork of [EvalPlus](https://github.com/neuralmagic/evalplus).
