+# Shortened LLM Model Card
+
+Shortened LLM is a depth-pruned version of large language models for efficient text generation.

+
+## Compression Method
+* After identifying unimportant Transformer blocks, we perform **one-shot pruning**.
+* In retraining pruned models for quality recovery, **continued pretraining (CPT)** on a large corpus markedly outperforms LoRA-based tuning, particularly at severe pruning ratios.

+#### Experimental Setup for CPT of Pruned Vicuna-7B
+* Dataset: [SlimPajama-627B](https://huggingface.co/datasets/cerebras/SlimPajama-627B) 
+* Training using 8 NVIDIA H100 GPUs.
+  * 5.5B parameters: 37B training tokens (for 6 days)
+  * 3.7B parameters: 74B tokens (for 8 days)
+  * 2.7B parameters: 150B tokens (for 12 days)
+  * 1.5B parameters: 271B tokens (for 11 days)
+* AdamW optimizer with (β1, β2)=(0.9, 0.95); a learning rate of 0.0001; a weight decay of 0.1.
+* Global batch size: 512 (micro-batch size of 2 × 32 gradient accumulation steps × 8 GPUs).

+**Zero-shot performance over the course of training for models from Vicuna-7B-v1.3 at different pruning ratios.** For each model size, the CPT duration was limited to a two-week period, but additional training could further improve the quality.
