How We Engineer Your
Fine-Tuned LLM
From raw data curation and synthetic dataset generation to LoRA parameter-efficient training and DPO preference alignment.
DATA INGESTION
Cleans PDFs, code & tickets into tokenized instruction pairs
LoRA ADAPTER
Injects low-rank trainable matrices into frozen base model weights
DPO / RLHF
Aligns model outputs to zero-hallucination compliance guardrails
QUANT & DEPLOY
Compacts into AWQ/GGUF format for ultra-fast private inference
Enterprise Data Preparation
We extract, clean, and structure your unstructured data PDFs, wikis, support tickets, codebases into high-quality instruction datasets.
Parameter-Efficient Fine-Tuning
Using LoRA and QLoRA, we train high-performing models efficiently no need for massive GPU clusters. Same outcomes at a fraction of the cost.
RLHF & Preference Alignment
Through RLHF and Direct Preference Optimization, we align model behavior precisely to your compliance requirements and brand voice.
Evaluation & Red-Teaming
Rigorous benchmarking against your domain-specific eval suite, adversarial stress tests, and accuracy scoring before deployment.
Deployment & MLOps
Monitoring pipelines, drift alerts, and automated retraining schedules keeping your model sharp as your business evolves.
Tailored For Your
Industry Use Case
Purpose-built models outperforming generalized AI across mission-critical enterprise domains.
Legal & Compliance
Train on contracts and precedents. Flags non-compliant clauses with attorney-level precision.
Code Assistants
Fine-tune on your codebase. Developers write code matching your internal architecture patterns.
Customer Support
Transform successful transcripts into training data. Handles tickets in your exact brand voice.
Medical Research
Adapt models to biomedical literature, trial data, and complex chemical structures.
Financial Analysis
Train on filings and earnings calls. Model speaks your fund's thesis natively.
Manufacturing
Encode manuals and failure modes. Predict equipment failures before they happen.
Cybersecurity
Fine-tune on threat intel and incidents. Triage alerts with your team's exact playbook.
Engineering Docs
Train on specs and SOPs for intelligent documentation assistance.
Zero Data Egress.
Private Infrastructure
Deploy models with 100% data sovereignty within your own VPC or on-premise hardware.
Air-Gapped Training
Full fine-tuning inside your VPC or on-premise hardware. Zero data egress. SOC 2 and HIPAA compatible workflows from the start.
Continuous MLOps
Production monitoring, drift detection, automated retraining triggers, and full model versioning with audit trails.
Edge & Quantized Deploy
INT4/INT8 quantization and GGUF compression for local server or edge device deployment at blazing speed.
