The problem

What you're seeing

Your AI feature works but the monthly API bill is climbing and your CFO wants a plan to cut it.

How we fix it

Our approach

We route to cheaper models when quality permits, add prompt caching, batch where it fits, and rewrite the worst token hogs. Bills typically drop 40–70% with no UX regression.

Symptoms

Symptoms teams come to us with

  • The model confidently invents facts and fake citations
  • You ship LLM changes by vibes, with no eval to catch regressions
  • API bills are climbing and finance wants a plan
  • RAG retrieves the wrong chunks or stale documents
Diagnosis

What we get right

  • 01Retrieval grounding and citation-required prompting
  • 02A scored eval harness wired into CI before changes ship
  • 03Model routing, caching and batching to cut token spend
  • 04Chunking, embeddings and re-ranking tuned for recall

Concrete deliverables, no fluff

Every engagement ends with measurable, documented outcomes — no black-box agency reports.

  • Evaluation harness with scored test cases

  • Implementation behind feature flags + rollback plan

  • Cost & latency dashboard wired to your observability

  • Hand-off doc covering prompts, models, and guardrails

How it works

From brief to shipped fix

A transparent, low-risk process — a senior engineer reads your brief personally, and nothing starts until you approve a written plan and price.

01Day 0–1

Diagnose

A senior engineer reviews your brief, reproduces the issue, and pinpoints the real root cause — not the symptom — before any code is touched.

02Within 24h

Scoped plan & quote

You get a written plan to reduce OpenAI / Anthropic API Costs, a firm timeline, and a fixed quote. Nothing starts until you approve it — no surprise invoices.

032–6 weeks

Ship the fix

We implement on a branch and open a pull request you review, working to your code-review standards on your repo — never a black box.

04On delivery

Verify & hand off

We verify on staging and production, share before/after evidence where it applies, and leave you a short hand-off note so the fix sticks.

Why Krapton

Why teams hand this task to Krapton

Senior engineers only

Your brief is read and handled by a senior engineer — no junior hand-off, no sales-rep filter in between.

Root cause, not a patch

We reproduce and fix the underlying cause, then add a guard so the same class of issue does not quietly return.

Your repo, your standards

Every change lands as a pull request you review, on your repository, following your existing review process.

NDA on day one

Confidentiality and IP are covered before we look at a single line of code. All work stays in your accounts.

Fixed quote up front

You approve a written plan and price before work starts. If scope changes, we re-quote in writing — no surprise invoices.

Proof, where it applies

Performance, SEO and reliability work ships with before/after evidence so the result is measurable, not anecdotal.

Engagement

Three ways to engage

No retainer required. Pick the model that matches the work — pricing for this task starts from $3,500, with a fixed quote before anything starts.

Per task

Most popular

One clearly-scoped fix at a fixed price. Best when you know exactly what is broken and want it handled end to end.

  • Fixed quote up front
  • One PR, reviewed by you
  • No retainer required

Hourly

Pay only for the hours worked. Best for diagnostics, audits, or exploratory work where the scope is still emerging.

  • Weekly timesheets
  • Pay for what you use
  • No minimum commitment

Per sprint

A focused 1–2 week sprint when the work is bigger than one fix but smaller than a full project.

  • 1–2 week blocks
  • Clear sprint goal
  • Scale up or stop anytime

Industry-standard stack, no proprietary lock-in

Yes. We work on your GitHub, GitLab or Bitbucket, ship every change as a pull request you review, and follow your code-review standards — not ours.

What exactly will I have at the end?

Concrete, documented outcomes — Evaluation harness with scored test cases, Implementation behind feature flags + rollback plan, Cost & latency dashboard wired to your observability, and more. No black-box agency report.

How quickly can you start, and do you sign an NDA?

For a focused task like this we can usually start within 24–48 hours of the brief. We sign an NDA on day one, before we look at any code — yours or ours.

We build a scored evaluation harness — golden set plus LLM-as-judge and human spot-checks — and gate changes against it, so you ship improvements you can prove instead of regressions you can't see.
