PEFT: Parameter-Efficient Fine-Tuning

Adapt LLMs and vision models faster with LoRA, QLoRA, adapters, and prompt tuning

Fine-Tune Large Language Models Efficiently with PEFT

Oodles helps enterprises specialize large language models using Parameter-Efficient Fine-Tuning (PEFT) techniques such as delivering LoRA, QLoRA, adapters, prefix tuning, and prompt tuning—delivering domain-aligned performance without the cost, risk, or infrastructure overhead of full model retraining. Our PEFT pipelines are built using PyTorch, Hugging Face Transformers & PEFT, bitsandbytes quantization, Accelerate, DeepSpeed, and modern evaluation frameworks—enabling faster iteration, lower GPU memory usage, and controlled, production-ready LLM deployments.

What Is PEFT?

Parameter-Efficient Fine-Tuning (PEFT) adapts large pre-trained transformer models by updating only a small subset of parameters—such as low-rank adapters, prefix vectors, or soft prompts—while keeping the base model frozen.

Oodles applies PEFT using LoRA, QLoRA, adapter layers, and prompt-based tuning combined with curated datasets, alignment strategies, and evaluation pipelines to deliver cost-efficient, reliable, and governable LLM solutions.

How PEFT goes live

A clear path from scoping to production with checks for safety, quality, and cost.

Goals & Constraints: Define tasks, latency/quality targets, compliance needs, and hardware budget.

Data & Guardrails: Curate datasets, synthesize where needed, de-duplicate, and set safety/policy rules.

PEFT Strategy & Training: Choose LoRA/QLoRA, adapters, or prompt tuning; run experiments with tracking.

Evaluation & Safety Sign-off: Run task-specific evals, red-team, and human review; document release criteria.

Deploy & Monitor: Package adapters, integrate with the base model, and monitor quality, cost, and performance during inference.
