Open source LLMs for business
Open source language models are models that are publicly available, so you can run them in your own environment.
That makes them the logical foundation for a private LLM: you keep control, prevent vendor lock-in and can fine-tune the model on your own data.
On this page you will read which models are available, what the advantages are and how Amaii deploys them securely.
Which open source models are there?
The landscape moves fast, but a few stand out:
Llama (Meta). A widely used model family, strong in general tasks and broadly supported.
Mistral. European models, known for their efficiency and strong performance at a smaller model size.
DeepSeek. Models that perform strongly on reasoning and coding tasks.
Which model fits depends on your task, your language and the available compute. We choose the model based on your situation, not the other way around.
Why do businesses choose open source models?
Control and sovereignty.
You run the model in your own environment, within the EU. Your data and your AI remain yours.
No vendor lock-in.
You are not chained to a commercial provider or its pricing and terms.
Customisation through fine-tuning.
Open models can be trained on your own documents, so they recognise your terminology and context.
Cost control.
No ongoing licence per user. You pay for infrastructure and management, not for every user account.
Open source versus commercial models
Commercial models are sometimes more powerful on the very broadest tasks and require less self-management. Open models give you control, sovereignty and the freedom to train on your own data, without handing your information over to third parties.
For organisations that work with sensitive data or value independence, that control often outweighs the last bit of extra capacity.

How Amaii deploys open models
We often work with open models that we fine-tune on your data, and host them within the EU or on-premise. This gives you customisation without building a model from scratch, on a foundation of security and full control.
