LLM integration & evaluation

Models wired into your product behind an interface you control, provider-agnostic by design. Every prompt and model change is gated on evals — measurable quality, not vibes.

  • Anthropic
  • Gemini
  • LangChain

// The problem

Why this is hard

Wiring an LLM into your product is easy; keeping it good is hard. A prompt tweak that helps one case quietly breaks three others, a provider outage takes your feature down, and 'is this better?' becomes a matter of opinion. Without an eval suite and a provider-agnostic interface, every change is a gamble and every vendor is a single point of failure.

// What we build

What you get

Provider-agnostic abstraction

An interface you control, so you can switch or blend providers without rewriting your product.

Eval & regression suite

Every prompt and model change gated on a measurable quality bar — no more 'seems better'.

Prompt & cost management

Versioned prompts and a cost/latency budget wired in, so quality and spend are both visible.

Streaming & structured output

Reliable structured output and streaming UX, validated against your schema.

// How we work

From prototype to production, in four moves.

01

Discovery

We map the problem, the data, and the eval that defines "done".

02

Prototype

A working slice in weeks — real model, real data, measured.

03

Production

Hardened, observable, evaluable. Shipped where users live.

04

Scale

Cost, latency and reliability tuned as load and scope grow.

// Typical engagement

What it takes to work together

  • Architecture Sprint

    $4–8kfixed · 1–2 wks

    1–2 weeks

    De-risk before you build — architecture, a plan, and a working proof-of-concept.

  • Build

    from$20kfixed scope or pod

    typically 1–3 months

    Ship the product end-to-end, in your repo and conventions.

  • Run & Scale

    from$4k/ month

    ongoing

    Operate and improve after launch — SLA, monitoring, and iteration.

Indicative ranges — the final price and timeline depend on your project's scope, complexity, and integrations. A paid Architecture Sprint pins them down.

Common questions

Because without one, a prompt change that helps one case can silently break others and 'is it better?' is just an opinion — evals gate every change on a measurable quality bar.

The model sits behind a provider-agnostic interface you control, so you can switch or blend providers without rewriting the product.

It depends on the task, and it changes fast — so we don't pick for you up front. We benchmark the candidates (OpenAI, Anthropic, Gemini, or an open/local model) on your eval suite and let the numbers choose per use case, then re-run it as new models ship.
