What We Do ?

What We Offer in Supervised Fine-Tuning

We specialize in supervised fine-tuning that aligns LLMs to your unique workflows, tone, and safety standards. Whether you’re tuning a legal advisor, internal chatbot, or multi-turn agent, we deliver labeled data pipelines, clean fine-tuning, and measurable performance boosts fast and responsibly.

Labeled Prompt–Response Dataset Creation

We design and label instruction–response pairs tailored to your product goals, tasks, or tone manually or with LLM help.

Domain-Aware Dataset Curation

We build fine-tuning sets from contracts, support logs, healthcare docs, legal FAQs, and more, cleaned and categorized by experts.

Data Augmentation for Class Balance

We expand small datasets with high-fidelity synthetic examples that maintain label quality and reduce task skew.

Fine-Tuning Pipelines (Full & PEFT)

We offer full model fine-tuning or parameter-efficient methods (LoRA, QLoRA) for fast, cost-effective training.

Task-Specific Output Control

We teach models to produce structured responses, comply with formatting, and stay on-task even under vague prompts.

Safety & Refusal Training

We incorporate labeled refusal scenarios and policy alignment, minimizing hallucinations and unsupported outputs.

Bias & Drift Evaluation

We test your model pre-/post-fine-tuning to measure output shifts, fairness impact, and knowledge retention.

Why Supervised Fine‑Tuning Is a Game Changer for LLM Performance

Supervised Fine‑Tuning isn’t just fine-tuning; it’s the fastest route to make models accurate, aligned, and production-ready. Here’s the data that proves it:

At Rain Infotech, we deliver supervised fine-tuning solutions that align language models with your specific tasks and domains. Our fine-tuned models are trained on high-quality labeled data, improving AI accuracy, reliability, and seamless integration across your existing systems.

SFT refines LLMs for specific tasks using limited labeled data

Even with smaller curated datasets, supervised fine-tuning effectively teaches models new behaviors and domain-specific responses.

Smaller curated datasets often outperform much larger noisy ones

Fine-tuned models show enhanced task accuracy, reduced errors, and smoother human-like interaction, leading to better user outcomes.

Labeled datasets of just 5K–10K samples are often enough for strong alignment

High-quality SFT datasets are both actionable and resource-efficient, enabling meaningful model customization without massive labeling efforts.

Small LLMs (3B–7B parameters) can match larger models when fine-tuned

Research shows that small models fine-tuned with quality instruction data outperform larger base models in tasks while using fewer resources.

SFT prevents overfitting and preserves pre-trained knowledge when done right

Structured SFT with validation safeguards models accuracy while minimizing catastrophic forgetting, delivering both alignment and retention.

FAQs

FAQs About Supervised Fine-Tuning

It’s the process of training a model on labeled input–output pairs so it learns to produce more task-specific and aligned responses.

Supervised Fine-Tuning uses static labeled data. Instruction tuning is a form of Supervised Fine-Tuning with instruction–response focus. RLHF builds on top of SFT using human preference signals.

Clear prompt–response examples that reflect real user tasks, formats, tone, and edge cases, ideally curated or reviewed by domain experts.

Effective fine-tuning often starts with just 5K–10K examples. We help assess volume and coverage based on your model and goals.

Yes. We support SFT on LLaMA, Mistral, Falcon, Yi, and more, plus help wrap, secure, and deploy your tuned models.

Yes, especially when combined with safety-focused prompts, refusal training, and bias testing tailored for compliance environments.

 

Absolutely. We support multilingual pipelines, tokenizers, and evaluation frameworks to tune across languages and scripts.

Not if done correctly. We use targeted tuning, validation checks, and loss balancing to preserve base knowledge while teaching new behaviors.
