Whittle 🪒🧠

Whittle is a Python library for compressing large language models (LLMs) by extracting sub-networks to balance performance and efficiency. It is based on LitGPT and allows to compress many state-of-the-art models.

• Neural Architecture Search: Workflows for pre-training super-networks and multi-objective search to select sub-networks.
• Structural Pruning: State-of-the-art approaches to pruning structural components of pre-trained LLMs.
• Distillation: Workflow to distill a student model given a trained teacher model.
• Evaluation: Easy extraction of sub-networks checkpoint and evaluation using LM-Eval-Harness
• Efficiency: Different metrics to estimate efficiency of sub-networks, such as latency, FLOPs, or energy consumption.

Installation

Whittle supports and is tested for python 3.10 to 3.12.
