Custom AI Development

When off-the-shelf isn't enough: custom models, fine-tuning, and production pipelines engineered by senior AI developers who ship to production, not demo day.

6–12 weeks from scoping to a production-grade AI system
100% model-agnostic — swap providers without a rebuild
0 shortcuts on evals, monitoring, or cost control

What's included

01

Model Selection & Fine-Tuning

The right model for your accuracy, latency, and cost targets — fine-tuned on your data where it pays off.

02

Data Pipelines

Embeddings, retrieval, and evaluation sets built on your data, not a generic benchmark.

03

Production Engineering

Latency, cost control, monitoring — the unglamorous parts done right so it holds up at scale.

04

Custom RAG Systems

Retrieval architecture tuned to your data shape — documents, structured records, or both.

05

Evaluation Frameworks

Automated eval sets so quality is measured, not guessed, before and after every change.

06

Zero Lock-In Architecture

Model-agnostic design — swap OpenAI, Anthropic, or open-weight models without a rebuild.

From scoping to production in four steps

1

Scope

A technical deep-dive into your accuracy, latency, and cost requirements.

2

Prototype

A working proof of concept against your real data, evaluated honestly.

3

Engineer

Production-hardening: monitoring, cost control, evals, and guardrails.

4

Operate

Ongoing tuning as usage and data grow — accuracy and cost stay on target.

Frequently asked questions

How much does custom AI development cost?+

Most custom AI builds run $25k–$90k depending on data complexity and scale. You get a fixed, milestone-based quote after a technical scoping call.

Do we need our own data science team?+

No. We handle model selection, fine-tuning, pipelines, and evaluation end to end — you just need domain knowledge of your business.

Will we be locked into one AI provider?+

No. We build model-agnostic architecture by default, so you can swap providers or self-host as pricing and capability shift.

How is this different from AI integration services?+

AI Integration wires existing models into your product fast. Custom AI Development is for when you need fine-tuning, proprietary pipelines, or accuracy targets off-the-shelf models can't hit.

Can you take over an AI system another vendor built?+

Yes. We start with an honest audit of the existing system — accuracy, cost, and architecture — before recommending a rebuild or an iteration path.
