OpenAI Integration

Frontier models, wired into the product you already have.

A chat box is the easy part. We integrate GPT and Claude so they call your APIs, act on your systems, stream instantly, stay within budget, and fail gracefully β€” the engineering that turns a model into a feature people rely on.

  • Provider-agnostic
  • Cost-controlled by design
  • Safe tool use & fallbacks

What an LLM integration really takes

From API key to a feature you can depend on

The gap between a weekend prototype and a production integration is all of this β€” and it's exactly where we live.

Function calling & tool use

The model triggers your real APIs under your permission rules β€” looking things up, taking actions, returning structured results.

Streaming & orchestration

Token-streaming UX, multi-step chains and agentic flows that feel instant and stay debuggable.

Cost & rate-limit control

Caching, model routing and token budgets that keep spend predictable and well under what naΓ―ve calls would cost.

Safety, PII & fallbacks

Input/output filtering, PII redaction, provider fallbacks and validation so the feature is safe and resilient.

How we integrate

Wired in weeks, not stuck in pilot

A clear path from 'we want AI in the product' to a guardrailed, cost-controlled feature in users' hands.

  1. 1

    Map the workflow

    We find where an LLM removes real work in your product, and what tools it needs to call to do it.

  2. 2

    Wire model + tools

    Provider-agnostic integration with function calling into your APIs, streaming UX, and structured outputs.

  3. 3

    Guardrail & cost-tune

    Validation, PII handling, caching and routing β€” so it's safe to ship and cheap to run at scale.

  4. 4

    Ship & observe

    Launch with monitoring on quality, latency and spend, plus fallbacks for when a provider has a bad day.

An integration, in production

Field & Form: LLMs wired into the tools they already used

A brand agency was losing its best hours to status meetings and manual prep. We integrated LLM summarisation into their existing stack β€” Slack, Notion, Asana β€” so updates wrote themselves and the team sold the hours it got back.

Straight answers

OpenAI integration questions

Do you only work with OpenAI?

No β€” we integrate OpenAI GPT, Anthropic Claude, and open-source models behind a provider-agnostic layer. That means we pick the best model per task and you're never stranded if pricing, limits or capabilities change.

How do you stop an LLM integration from running up a huge bill?

Cost control is part of the build: prompt and context trimming, response caching, model routing (cheap model first, escalate only when needed), token budgets, and dashboards that tie spend to usage. You get the capability without an unbounded invoice.

What is function calling and why does it matter?

Function calling lets the model trigger your real APIs β€” look up an order, create a ticket, send an email β€” instead of just chatting. It's what turns an LLM from a text box into something that actually does work inside your product, safely and with your permission rules.

How do you handle reliability when the model or API misbehaves?

Retries, timeouts, fallbacks to a secondary provider, output validation, and graceful degradation so a model hiccup never takes down your feature. We treat the LLM like any other unreliable dependency and engineer around it.

Can you add AI into our existing app without a rebuild?

Yes β€” most integrations slot into your current stack via APIs and SDKs. We read from the tools you already use and add the AI layer on top, rather than asking you to migrate.
