LLM Integration

LLM integration into
the stack you already have.

Our LLM integration services connect production language models to the APIs, databases, and tools you're already running — no rip-and-replace, no six-month platform migration before you see any value.

Serving UK and EU clients: GDPR, EU AI Act, data residency, and VPC / on-premise deployment options are covered on our Trust & Safety page.

What it is

Adding AI without
a rebuild.

LLM integration is the work of connecting a language model to your real systems — your product's database, your internal APIs, your auth, your existing UI — so it can act on real data instead of answering in a vacuum. It's the layer that turns "we tried ChatGPT and it was fine" into a feature your product actually ships.

Done right, it's additive: the model sits alongside your current stack, calling into it through the same interfaces your engineers already use, which means your team can maintain and extend it without needing to understand a new platform first.

How we build it

Built to control
cost at scale.

We've seen inference costs blow up 40x when none of this is in place from day one. Every integration we ship includes it by default.

01Token budgeting

Per-request limits and prompt design that keep context lean, so cost scales with actual usage, not with how verbose a prompt happened to get.

02Caching for repeat queries

Responses to common or repeated requests are cached instead of re-generated, cutting both latency and spend on the queries that show up most.

03Model routing

Simple requests go to smaller, cheaper models; the larger model is reserved for requests that actually need its reasoning. See our Trust & Safety framework for how this is monitored in production.

Common questions

Before you
book a call.

The questions we get asked most about LLM integration — answered straight, no sales pitch.

How long does LLM integration take?

A single integrated workflow — one feature, connected to your existing data and one or two systems — typically ships in weeks, not months. Timeline scales with how many systems the integration needs to touch and how clean the existing APIs are, which we scope upfront rather than discovering mid-project.

Do we need to rebuild our stack to add AI?

No — that's the premise of LLM integration as opposed to a greenfield AI product. We connect to your existing APIs, databases, and auth rather than asking you to replace them. A rebuild is occasionally the right call, but it's the exception, not the default.

How do you control LLM inference costs at scale?

Token budgeting per request, response caching for repeated queries, and routing simpler requests to smaller/cheaper models while reserving the larger model for requests that actually need it. We've seen inference costs blow up 40x at scale when none of this is in place from the start.

Can you integrate agents or RAG into our product too?

Yes — LLM integration is often the connective layer underneath an agent or a RAG system. See our AI agent development and RAG development work for those specific builds.
