LLM integration & advisory

We help teams adopt large language models with engineering discipline: what to build, which model to use, when fine-tuning is worth it, and how to prove the system works before it meets customers.

1 · Prompting days · lowest cost 2 · + RAG weeks · moderate cost 3 · + Fine-tuning months · highest cost only if evals fall short only if evals fall short EVALUATION ON YOUR GOLDEN SET prompting 0.74 + RAG 0.89 + fine-tuning 0.91 target 0.85 Verdict: ship RAG. fine-tuning buys +0.02 for ~3× the cost — not yet worth it
The advisory logic in one picture: escalate capability only when your own evaluation says the simpler tier falls short. Values illustrative.

What this covers

  • Feasibility & architecture — a short, honest assessment of whether your use case needs an LLM at all, and the simplest architecture that meets it.
  • Model selection & cost — hosted frontier models vs. open-weight, latency and cost modeling at your real traffic, and exit strategies so you are not locked in.
  • Prompting, RAG, or fine-tuning — chosen from evidence on your data, in that order of preference, because each step up costs more to build and maintain.
  • Evaluation & safety — golden sets, regression harnesses, red-team passes, and guardrails appropriate to your risk profile.

Where it works well

Teams about to commit significant budget to an AI feature, organizations burned by a demo that never reached production, and companies that need a second opinion in plain language — English or Korean — before signing a vendor contract.

Common questions

Do you resell a particular model or platform?
No. We have no reseller agreements, so recommendations follow your requirements and measured results rather than a commission.
Can you work with our in-house developers?
That is the preferred mode. We design alongside your team and hand over code, evals, and runbooks so capability stays in-house after the engagement.
What does an advisory engagement cost?
Advisory work is scoped as a short fixed-price assessment first, so you know the full cost before committing. Contact us with your use case for a same-week estimate.
