The Problem

Off-the-Shelf AI Wasn't Built for Your Industry

Foundation models are trained on the internet — not your contracts, your clinical notes, your engineering specs, or your customer data. The performance gap shows.

Generic Models Miss Domain Context

GPT and similar models hallucinate industry-specific terms, misinterpret regulatory language, and produce outputs that require heavy human review.

Data Privacy Violations Using Public APIs

Sending proprietary contracts, patient data, or trade secrets to third-party model APIs creates serious IP and regulatory exposure.

Accuracy Too Low for Production Use

A generic model achieving 72% accuracy on your classification task is unusable. A fine-tuned model on your data can reach 94%+.

Latency and Cost at Scale

Routing every inference through a third-party API creates latency, rate limits, and per-token costs that become prohibitive at enterprise volumes.

The Solution

Fine-Tuned, Domain-Specific AI Owned by You

LLM fine-tuning adapts a strong base model to your terminology, workflows, and accuracy thresholds without starting from zero. We build custom AI models through model fine-tuning, domain-specific classifiers, and specialized generative systems trained on your proprietary data and deployed in your environment, with LoRA, RLHF, eval sets, and monitoring matched to your use case.

Before You Build

Evaluating a Custom AI Model

What teams weigh before commissioning a custom model — fine-tuning versus RAG versus training, data needs, open versus proprietary models, timeline, proving accuracy, and keeping it accurate.

8 questions answered

Should we fine-tune a model, use RAG, or train one from scratch?

It depends on the goal. Fine-tuning adapts an existing model to your tone and tasks; RAG grounds answers in your live documents without retraining; training from scratch is rare and only worth it for unique data types. Most production systems combine fine-tuning with retrieval-augmented generation, and we benchmark each for your case.

How much of our own data do we need to build a custom model?

Often less than you'd expect. Fine-tuning a strong open model can work with a few hundred to a few thousand well-labeled examples; embeddings and RAG need your documents, not labeled training data. Quality beats quantity. Where data is thin or messy, our data engineers clean and label it first.

Should we use an open-source model (LLaMA, Mistral) or a proprietary one (GPT, Claude)?

Open models like LLaMA or Mistral give you full control, private deployment, and no per-token fees — ideal when data can't leave your environment or volume is high. Proprietary models can lead on raw capability for some tasks. We pick per use case and weigh both in your custom AI build.

How long does it take to build a custom AI model?

A first fine-tuned or domain model often reaches a validated, production-ready result in weeks, depending on data readiness and task complexity. We start with a focused proof of value, then harden and expand it. A dedicated AI/ML team running data prep and training in parallel keeps the timeline tight.

How do you prove the model is accurate enough before we trust it in production?

We define success metrics up front and benchmark every model against held-out data from your domain — measuring accuracy, precision, and error ranges, not vague claims. You review results on your own data before launch. After go-live, production monitoring tracks performance so quality issues surface immediately, not months later.

How do you keep the model accurate as our data and business change?

Models drift as real-world data moves away from what they trained on, so we monitor performance, alert on decay, and retrain on fresh data when needed. Automated retraining pipelines make this routine rather than a fire drill. That ongoing AI automation keeps your model accurate long after the first launch.

What does LLM fine-tuning involve, and when is it worth it?

LLM fine-tuning involves selecting a base model, preparing labeled examples, training with methods like LoRA, and validating on eval sets that reflect your actual task. It is worth it when prompts alone cannot deliver the tone, structure, or domain accuracy you need. If the use case starts with user-facing interaction, we often connect it to conversational AI delivery next.

Can you build a custom LLM for our domain?

Yes. We can build a custom LLM for your domain by adapting an open-weight base model to your terminology, content, and evaluation targets, then deploying it in your environment with clear ownership and monitoring. The right fit still depends on data quality, risk, and industry constraints, so we usually validate those first across your industry context.
