It was then quantized to 8-bit weights + activations and exported to deploy with [DeepSparse](https://github.com/neuralmagic/deepsparse), a CPU inference runtime for sparse models. Official model weights from [Enabling High-Sparsity Foundational Llama Models with Efficient Pretraining and Deployment](https://arxiv.org/abs/2405.03594). **Authors**: Neural Magic, Cerebras ## Usage Below we share some code snippets on how to get quickly started with running the model. ### Sparse Transfer By leveraging a pre-sparsified model's structure, you can efficiently fine-tune on new data, leading to reduced hyperparameter tuning, training times, and computational costs. Learn about this process [here](https://neuralmagic.github.io/docs-v2/get-started/transfer). ### Running the model For accelerated inference with sparsity on CPUs, deploy with [deepsparse](https://github.com/neuralmagic/deepsparse). ```python # pip install deepsparse[llm] from deepsparse import TextGeneration model = TextGeneration(model_path="hf:neuralmagic/Llama-2-7b-pruned70-retrained-ultrachat-quant-ds") input_text = "Write me a poem about Machine Learning." outputs = model(input_text, max_new_tokens=100) print(outputs.generations[0].text) ``` ## Evaluation Benchmark Results Model evaluation metrics and results. | Benchmark | Metric | Llama-2-7b-ultrachat | Llama-2-7b-pruned70-retrained-ultrachat-quant-ds | |------------------------------------------------|---------------|-------------|-------------------------------| | [AlpacaEval](https://arxiv.org/abs/2107.03374) ([Llama-2-70b-chat-hf](https://huggingface.co/meta-llama/Llama-2-70b-chat-hf) evaluator) | Win rate | 57.6% | 57.1% | ## Help For further support, and discussions on these models and AI in general, join [Neural Magic's Slack Community](https://join.slack.com/t/discuss-neuralmagic/shared_invite/zt-q1a1cnvo-YBoICSIw3L1dmQpjBeDurQ)
