This is a code completion AI model obtained by fine-tuning the 2:4 sparse Sparse-Llama-3.1-8B-2of4 on the evol-codealpaca-v1 dataset. On the HumanEval benchmark, it achieves a pass@1 of 49.1, compared to 48.5 for the fine-tuned dense model 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. 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 backend. vLLM aslo supports OpenAI-compatible serving. See the documentation for more details.

Evaluation

This model was evaluated on Neural Magic's fork of EvalPlus.
