Your terminology
A model that knows your words.
Teach an open model the names, terms and language of your business and your clients.
LLM fine-tuning: AI trained on your own data
AI that speaks your business: adapt open models to your terminology, documents and style on hardware you own, with your training data kept private. Renderboxes can help you put powerful local AI compute to work.
The possibilities with private, local AI
Your house style
Writing that sounds like you.
Adapt a model to your tone of voice for reports, proposals and client communication.
Your specialist tasks
Better at the jobs you do most.
Tune models for classification, extraction or support tasks specific to your work.
Image and style models
Your look, on demand.
Train image models on your own products, characters or visual style.
Private training data
Nothing leaves the building.
Train on client and company data that could never be sent to a cloud service.
Own the result
The tuned model is yours.
Keep, version and run the models you train, with no lock-in to a provider.
Local AI capabilities, model support and performance vary by model, configuration, software and workload.
Protect your business
We can help you build AI workflows that protect your business.
- Help keep your data secure. Prompts, documents and answers are processed on your own hardware, on your own network. Nothing is retained by an AI provider and nothing trains someone else’s model.
- Your identity, protected. Personal and confidential details can be masked automatically at every exit, so only what is safe to send ever leaves the building.
- A record you own. Every request and action can be logged to a tamper-evident audit trail on your own disks, which helps you meet client confidentiality and GDPR obligations.
Reduce token costs
PREDICTABLE COSTS FOR THE WHOLE TEAM
Replace per-seat AI subscriptions and usage-based token fees with a fixed cost for on-premises compute your whole team can share. Workflows can be set up to check your own knowledge before a paid cloud call, and any cloud use can be capped, with a kill switch that you control.
Ready on day one: RBOS and RBOS Studio
Skip the weeks of set-up. RBOS and RBOS Studio can come preloaded, configured and tested together, so your team starts on the work, not the software.
- One-click workflows. Runbooks set up team chat, document search, coding assistants, transcription and model serving with step-by-step guidance.
- Your team gets simple, IT keeps control. Everyone works in a browser on your network, while admins decide who can use what and every action is logged.
- Change it as your work changes. Add or remove workflows at any time, with no endless tweaking.
- See every GPU at work. Assign workflows to GPUs and see what each one is doing.
Works with the software you use
We can set up, test and support popular AI software on your machine before it ships, including:
LLaMA Factory · Unsloth · Hugging Face Transformers · PyTorch · AI Toolkit

Built on NVIDIA RTX PRO Blackwell
These workflows rely on the NVIDIA software ecosystem, so we build them on NVIDIA RTX PRO Blackwell GPUs, with up to 96GB of VRAM on each card.
- The broadest software support for creative, training and research AI tools.
- Workstation-class GPUs built for sustained load, all day.
- Room to grow from one GPU to eight as your work does.

Frequently asked questions
It helps, but it is not essential to get started. Runbooks guide the set-up, and we can help you plan and run your first project.
No. RBOS Studio runs in a browser, and Runbooks guide you through set-up step by step. We can also set the machine up for your workflows before it ships.
Not unless you choose to. Everyday work runs on the machine. If you use a cloud model for harder tasks, personal and confidential details can be masked before anything is sent.
It can. You could keep the machine for private and everyday work and use a cloud model only for the hardest tasks, with spending capped. We can help you set that up.
That depends on your workflows and how heavily they are used. Tell us about your team and we will size the machine for it.
Many of the tools behind these workflows are built for NVIDIA first, so we build them on NVIDIA RTX PRO GPUs for the widest software support.
Yes. We keep developing new workflows, and if you need one we do not list, talk to us and we will help you make it work.
Yes. Select Customise and the configurator opens with this build already selected.
