Large language model APIs, integrated with care.

Language models from OpenAI, Azure OpenAI and AWS Bedrock, integrated safely.

Overview

What OpenAI & LLM APIs is, and why teams choose it

Large language model (LLM) APIs from providers such as OpenAI, Azure OpenAI and AWS Bedrock let applications understand and generate text, extract structured data, call tools and work with images. They are consumed as cloud services, so there is no model to host or train.

Teams use LLM APIs to add capabilities that were impractical a few years ago: answering questions from documents, summarising, drafting and turning messy text into structured data. Doing it well is an engineering problem: grounding answers in your data, handling failures, testing quality and controlling cost.

Why it’s a good choice

  • Powerful capabilities without training your own model
  • Several providers, including options inside Azure and AWS
  • Structured outputs and tool calling for reliable integration
  • Pay-as-you-go pricing that can start small

What we build

What we build with OpenAI & LLM APIs

  • 01

    Retrieval-augmented generation

    Pipelines that chunk, embed and index your documents, retrieve the right passages and generate answers with citations.

  • 02

    Structured extraction

    Schema-constrained outputs that turn emails, PDFs and forms into validated records your systems can store.

  • 03

    Tool-calling agents

    Models that call your APIs through narrowly defined tools, with approval steps for consequential actions.

  • 04

    Evaluation harnesses

    Test sets and automated scoring, so prompt or model changes are measured before they are released.

  • 05

    Provider abstraction

    A thin internal layer that lets you switch between OpenAI, Azure OpenAI and Bedrock models without rewriting features.

Our approach

Engineering practices we bring to every build.

How we keep OpenAI & LLM APIs work tested, fast, secure and easy to release.

  • Evaluation

    Every LLM feature gets a test set built from real examples and a quality bar agreed with the business before launch.

  • Security

    Prompt-injection defences, least-privilege tools, output validation and no secrets or unnecessary data in prompts.

  • Cost control

    Model choice by task, caching, context limits, token tracking per feature, and budgets with alerts.

  • Reliability

    Timeouts, retries with backoff, fallbacks to simpler behaviour and clear messages when the AI is unavailable.

Typical use cases

  • Document Q&A and knowledge assistants
  • Email and ticket triage
  • Draft generation with human review
  • Data extraction from unstructured documents

FAQ

OpenAI & LLM APIs questions, answered.

Can’t find what you’re looking for? Ask us directly. We’re happy to talk it through.

Both provide access to similar model families. Azure OpenAI runs inside Microsoft Azure, with regional deployment options and Azure’s identity and networking controls, which many Microsoft-centred organisations prefer. OpenAI’s own API often gets new models and features first. We help you weigh those trade-offs.
