LLM Quantization

Compress and accelerate LLMs for edge and cloud deployment with state-of-the-art quantization techniques. Reduce model size by 75% while maintaining 95%+ accuracy.

Overview

Quantization compresses neural network weights from 32-bit floats to lower-bit formats (8-bit, 4-bit, or even 2-bit), dramatically cutting model size and accelerating compute, enabling deployment on constrained hardware without major accuracy loss.

State-of-the-Art Methods and Architectures

Post-Training Quantization (PTQ)
Applies quantization after model training, minimal code changes. Techniques: dynamic range quantization, per-channel PTQ.
Quantization-Aware Training (QAT)
Simulates quantization noise during training for robust performance post-quantization. Often yields <1% degradation on benchmarks.
GPTQ (Hessian-Aware Quantization)
Leverages second-order Hessian information to optimize rounding decisions per weight group. Retains performance of 4-bit models on language benchmarks.
Double & Mixed-Precision Quantization
Combines 4-bit storage for weights and activations with 16-bit or 8-bit compute paths. Balances memory savings and numerical stability on larger models.

Implementation Guide

1
Select Quantization Strategy
PTQ vs. QAT vs. GPTQ based on hardware and latency goals.
2
Implement Tooling
Use libraries like bitsandbytes, nn-meter, or TensorRT.
3
Validate Performance
Compare GLUE / LAMBADA metrics pre- and post-quantization.
4
Integrate into CI/CD
Automate quantization and regression testing in model release pipelines.

Technical Deep Dive

Data Preparation

Collect domain-specific text (e.g., medical records, legal documents). Clean and format data into JSONL.

Adapter Insertion

Insert LoRA/QLoRA adapters into the base model.

Training

Run training with domain data, using a learning rate schedule and early stopping. Monitor loss and validation metrics.

Evaluation

Use ROUGE, accuracy, or custom metrics. Compare outputs to base model.

Sample Code

from transformers import AutoModelForCausalLM, TrainingArguments, Trainer model = AutoModelForCausalLM.from_pretrained('llama-7b') # Insert LoRA adapters... # Prepare data... trainer = Trainer(model=model, args=TrainingArguments(...), train_dataset=...) trainer.train()

Why Fine-Tuning?

Full-Precision Model
- 32-bit weights - High memory and compute - Best accuracy - Not suitable for edge devices
Quantized Model
- 4/8-bit weights - Low memory and compute - Slight accuracy drop - Runs on edge/mobile/cloud
