IN PLAIN ENGLISH

What Is Open-Source LLM Implementation – and What We Do Differently

Open-source LLM implementation means choosing an openly licensed model and running it on infrastructure you control. You get privacy and predictable costs, but you take on hosting. We size the hardware realistically, compare open models with commercial ones on your tasks, and are honest when a commercial API would serve you better.

SOUND FAMILIAR?

Business Problems Our Open-Source LLM Implementation Solves

Data Too Sensitive for Public AI APIs

Legal, health and financial data often cannot be sent to third parties. A private model keeps it on servers you control.

Per-Request Costs That Grow Every Month

At high volume, API bills add up. A self-hosted model costs the same whether you use it lightly or heavily.

Dependence on One Provider’s Terms and Prices

Providers change prices, models and policies. An open model you host cannot be withdrawn or repriced.

Confusion About Hardware and Licences

Which model, which GPU, which licence allows commercial use? We answer those questions before you spend on hardware.

WHAT WE BUILD

Our Open-Source LLM Implementation Services

Model Selection & Licence Review

Open models compared on your tasks, with licence terms checked for commercial use.

Private Cloud Deployment

Models deployed on AWS, Azure or Google Cloud GPUs in UK or EU regions.

On-Premise Deployment

Models running on your own hardware, fully offline if needed.

Inference Optimisation

vLLM, quantisation and batching to serve more users on less hardware.

OpenAI-Compatible API

Your private model exposed through a standard API, so existing tools work with it.

Private RAG with Open Models

Document search and answering where neither documents nor questions leave your network.

Fine-Tuning Open Models

Open models trained on your examples for specialist tasks.

Monitoring & Updates

GPU usage, speed and quality monitored, with model upgrades when better versions arrive.

HOW WE WORK

How Our Open-Source LLM Implementation Process Works

  1. 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.

  2. 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.

  3. Build & Integrate

    We build the prompts, guardrails and integration, and fine-tune or adapt the model where testing shows it is worth it.

  4. 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.

  5. Monitor, Optimise & Scale

    We monitor quality, latency and spend, and move to newer or cheaper models when they do the job as well.

TECHNOLOGY
