IN PLAIN ENGLISH
What Is LLM Integration – and What We Do Differently
LLM integration means connecting a model such as GPT, Claude or Gemini to your systems through an API, so it can read the data it needs and send results back. Calling an API is easy. Doing it safely is the real work: handling failures, protecting personal data, controlling cost and making it easy to switch models later.
SOUND FAMILIAR?
Business Problems Our LLM Integration Solves
Locked in to One AI Provider
If your code only works with one model, you cannot switch when a better or cheaper one appears. We build a layer that makes switching simple.
No Record of What the AI Did
Without logs, nobody can check what was sent or why an answer was given. We log every request and response.
Unexpected API Bills
A loop or a busy day can run up costs fast. Usage limits and alerts keep spending under control.
WHAT WE BUILD
Our LLM Integration Services
OpenAI GPT Integration
GPT models connected through the OpenAI API or Azure OpenAI for UK and EU hosting.
Anthropic Claude Integration
Claude connected directly or through AWS Bedrock, ideal for long documents and careful writing.
Google Gemini Integration
Gemini through Vertex AI, a good fit for Google Workspace and Google Cloud users.
Multi-Model Gateway
One internal API that routes to different models, so you can switch without rewriting code.
CRM & Help Desk Integration
LLM features inside HubSpot, Salesforce, Zendesk and similar tools.
Personal Data Redaction
Names, emails and sensitive details removed or masked before data reaches the model.
Logging & Audit Trails
Every request, response and cost recorded for review and compliance.
Rate Limits & Cost Controls
Spending caps, alerts and fallbacks so costs never surprise you.

HOW WE WORK
How Our LLM Integration Process Works
AI Opportunity Audit
We look at the task, your data and your limits on cost, speed and privacy, then test a few models on real examples.
Roadmap & ROI Forecast
You get a plan showing which model we recommend, how it will be hosted, the expected cost per month and the benefit.
Build & Integrate
We build the prompts, guardrails and integration, and fine-tune or adapt the model where testing shows it is worth it.
Test, Train Your Team & Launch
We measure output against a test set your team approves, train users and launch with usage and cost limits in place.
Monitor, Optimise & Scale
We monitor quality, latency and spend, and move to newer or cheaper models when they do the job as well.
TECHNOLOGY
AI Models & Platforms We Work With
We are not tied to one vendor. We choose on accuracy, cost and where your data needs to live.
AI Models (OpenAI GPT, Claude, Gemini, Llama)
Commercial and open-source models, compared on your own data before we recommend one.
Hosting & Fine-Tuning Platforms
Azure OpenAI, AWS Bedrock, Google Vertex AI, Hugging Face and self-hosted GPUs for private models.
CRMs & Business Tools
HubSpot, Salesforce, Zoho, Microsoft 365, Google Workspace and your own databases and apps.
