AI Bills Growing Faster Than Usage
Costs climb each month and nobody is sure why. Usage analysis usually shows a few expensive patterns that can be fixed.

IN PLAIN ENGLISH
What Is LLM Optimisation – and What We Do Differently
LLM optimisation means making an existing AI system cheaper, faster or more accurate. Common fixes include sending simple tasks to smaller models, caching repeated answers and trimming prompts. Every change we make is tested against a quality score, so you get savings you can trust, not savings that quietly make answers worse.
SOUND FAMILIAR?
Business Problems Our LLM Optimisation Solves
Users Waiting Too Long for Answers
Ten seconds feels like forever in an app. Streaming, smaller models and parallel calls cut waiting times.
The Biggest Model Used for Every Task
Simple sorting does not need the most powerful model. Routing tasks to the right model can cut costs dramatically.
Prompts That Have Grown Out of Control
Instructions added over months make every request long and expensive. A clean rewrite often improves results too.
WHAT WE BUILD
Our LLM Optimisation Services
Cost & Usage Audit
A breakdown of where your AI spend goes, by feature, model and user.
Model Routing
Simple tasks sent to smaller, cheaper models and hard ones to stronger models.
Prompt Compression & Rewriting
Shorter, clearer prompts that cost less and often perform better.
Semantic Caching
Repeated or similar questions answered from cache instead of a new model call.
Latency Reduction
Streaming, parallel calls and faster models to cut response times.
Batch Processing
Non-urgent jobs moved to batch APIs at a lower price.
Quality Regression Testing
Every change checked against a test set so quality never slips.
Cost Monitoring & Alerts
Dashboards and alerts that catch cost spikes the day they happen.

HOW WE WORK
How Our LLM Optimisation 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.
