Original model description:
Shortened LLM Model Card
Shortened LLM is a depth-pruned version of large language models for efficient text generation.

- Repository: https://github.com/Nota-NetsPresso/shortened-llm
- Paper: https://arxiv.org/abs/2402.02834
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
- 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.
