About This Service

What Is LLM Development?

Most "LLM development" is a system prompt around a public API. We go further. iMOBDEV's LLM team fine-tunes open-source and proprietary models on your proprietary data, builds evaluation harnesses that catch regressions before they ship, and optimizes inference so your unit economics survive scale. We've trained domain-specific models for legal document review, medical coding, and financial compliance — cases where a generic model's accuracy simply isn't good enough. Whether you need a fine-tuned Llama 3 model running on your own infrastructure for data residency reasons, or a distilled small model for low-latency edge inference, we handle the full lifecycle: data curation, training, evaluation, quantization, and production deployment. Our engineers have backgrounds in both applied machine learning research and shipped production systems, so recommendations are grounded in what has actually worked for comparable clients, not theoretical capability. We're equally comfortable extending a proprietary model via an API and training an open-weight model from scratch on your infrastructure.

What's Included

Everything in Scope

A full breakdown of every deliverable — no hidden extras, no scope surprises.

Custom LLM Fine-Tuning

LoRA, QLoRA, and full fine-tuning on Llama 3, Mistral, and Falcon for domain-specific accuracy and tone

Private & On-Premise LLM Deployment

Self-hosted LLMs on your VPC or on-prem GPUs for data residency, compliance, and cost control at scale

Model Distillation & Quantization

Shrink large models into fast, cheap-to-run variants using GGUF, AWQ, and knowledge distillation

LLM Evaluation & Benchmarking

Custom eval harnesses measuring accuracy, hallucination rate, and latency before every release

RLHF & Alignment Tuning

Reinforcement learning from human feedback to align model behavior with your brand voice and safety requirements

LLM Inference Optimization

vLLM, TensorRT-LLM, and batching strategies that cut inference cost without sacrificing response quality

Why Work With Us

What You Get When You Choose iMOBDEV

Beyond Prompt Engineering

We fine-tune and train models when prompting alone can't hit your accuracy bar — a distinction most "AI agencies" skip entirely.

Data Never Leaves Your Control

Private deployments on your cloud or on-prem hardware, with training data pipelines that never touch third-party APIs.

Inference Cost Engineering

Quantization and serving optimization routinely cut inference costs 40-70% versus naive API-based deployments.

Rigorous Evaluation, Not Vibes

Every fine-tuned model ships with a benchmark suite comparing it against baseline — no "it feels better" launches.

ML Scientists, Not Just Engineers

Our LLM team includes researchers with published fine-tuning and RLHF experience, not just API integrators.

How We Deliver It

Discovery & Scoping

Deep dive into your goals, users, and constraints. Deliverable: detailed project brief and technical specification.

Architecture & Design

System architecture, API contracts, UI/UX wireframes reviewed with your team before a line of code is written.

Agile Development

2-week sprints with daily standups. Working software demonstrated every sprint — full visibility throughout.

QA & Testing

Automated unit and integration tests plus manual QA each sprint. Zero critical bugs shipped to production.

Deployment & Launch

CI/CD pipeline, cloud provisioning, zero-downtime deployment. Launch day is never a surprise.

Support & Growth

Post-launch monitoring, performance optimization, and ongoing feature roadmap execution.
