To use AI offline, install a local runner such as Ollama or LM Studio, download an open-weight small language model (for example Llama 3.1 8B, Mistral 7B or Phi-4-mini), and run it on your own laptop or server. Prompts and documents never leave the device, which is why many Australian organisations that block ChatGPT allow approved local AI.
Many organisations restrict public AI websites to protect confidential information. The good news is that capable models now run entirely on a modern business laptop, with no internet connection after download and no API calls to external servers.
This guide covers how local AI works, which tools and models to use, hardware requirements, step-by-step setup, realistic use cases, and how to approach IT. It is for staff and IT teams at Australian organisations that need AI without sending data offshore.
Key takeaways
- Local AI runs the model on your own hardware, so data stays on the device.
- LM Studio is the easiest start; Ollama is the most flexible and powers many other tools.
- Small language models (3 to 8 billion parameters) handle drafting, summaries and formatting on a 16GB laptop.
- Local models trail the largest cloud models on complex reasoning and very long documents.
- Use them inside an approved policy: IT approval, approved models, and rules on what data can be processed.
Why do companies block cloud AI tools?
When you type into a public AI website, your text travels over the internet to servers usually in the US or EU, may be logged or retained, and the response comes back.
- You TypeEnter your question
- Data SentOver the internet
- External ServerOften processed offshore
- Stored or LoggedPotentially retained
- ResponseSent back to you
Data leakage is real. Group-IB reported in 2024 that more than 225,000 sets of OpenAI ChatGPT credentials were found for sale, harvested from employee devices by infostealer malware, which would expose chat histories to whoever logged in. In 2023 Samsung staff uploaded proprietary source code to ChatGPT, and several banks restricted the tool while they assessed it.
Compliance obligations apply. Depending on your sector and data:
| Obligation | What it covers | AI risk |
|---|---|---|
| Privacy Act 1988 (APP 8) | Personal information | Cross-border disclosure |
| APRA CPS 234 | Information security in regulated entities | Uncontrolled third-party data flows |
| Legal professional privilege | Lawyer-client communications | Risk of waiver |
| Health records laws | Health information | Sensitive data exposure |
| GDPR | EU personal data | Data leaving jurisdiction |
Intellectual property. Terms on training and retention vary by product and can change. With local AI, prompts stay on hardware you control. Our piece on how the wrong AI tools leak business data goes deeper.
What is local AI and how does it work offline?
Local AI runs the model directly on your computer.
- You TypeEnter your question
- Your CPU/GPUProcesses locally
- Local ModelStored on your drive
- ResponseNever leaves the device
- Privacy: data stays on the device.
- No per-use fees: open-weight models are free to download; you pay for hardware.
- Works offline: on a plane, at a remote site, in a secure facility.
- No rate limits: throughput is limited only by hardware.
- Control: you choose the model and its version.
The trade-off: local models are smaller than the largest cloud models. For routine office work (drafting, summarising, meeting notes, formulas) they are more than capable.
Which local AI tools should you use?
| Ease of Use | Flexibility | Impact | |
|---|---|---|---|
| LM Studio | Easiest (desktop app) | High | Best for beginners |
| Ollama | Easy (command line) | Highest | Best for power users and integration |
| Jan | Very easy | Medium | Polished open-source app |

GPT4All: simple desktop app
From Nomic AI, designed for consumer hardware, with a basic but functional interface and models typically a few gigabytes in size.
Which small language model should you download?
What's your primary use case?
- General tasks (email, summaries, Q&A)Llama 3.1 8B or Mistral 7B
- Coding and technical workDeepSeek-R1-Distill-Qwen-7B or a Qwen coder model
- Limited hardware (8GB RAM or less)Phi-4-mini (3.8B), Llama 3.2 3B or Qwen 2.5 3B
- Complex reasoning and analysisA 32B to 70B model, if hardware allows
What is a small language model?
A small language model has roughly 1 to 10 billion parameters, small enough to run on a laptop. They handle structured, everyday language tasks well and use far less memory than frontier cloud models.
All-round models
- Llama 3.1 8B (Meta): about 5GB download; 8GB RAM minimum, 16GB recommended. A good balance of capability and hardware.
- Mistral 7B (Mistral AI): about 4GB; 8GB RAM. Fast and dependable for summaries and drafting.
Small but capable
- Phi-4-mini (Microsoft, 3.8B): about 2.5GB; runs on 4 to 8GB RAM. Strong for its size.
- Llama 3.2 3B (Meta): the default
llama3.2in Ollama, about 2GB. Good on older laptops. - Qwen 2.5 3B (Alibaba): about 2GB; strong multilingual support.
Maximum capability
- DeepSeek-R1-Distill-Qwen-32B: about 20GB; 32GB+ RAM. Strong reasoning and coding.
- Llama 3.1 70B: about 40GB; 64GB+ RAM or a large GPU.
| Model | Download | RAM needed | Best for |
|---|---|---|---|
| Phi-4-mini (3.8B) | ~2.5GB | 4-8GB | Lightweight tasks |
| Llama 3.2 3B | ~2GB | 4-8GB | Older laptops |
| Mistral 7B | ~4GB | 8GB | General use, fast |
| Llama 3.1 8B | ~5GB | 8-16GB | All-round |
| DeepSeek-R1 Distill 7B | ~5GB | 8-16GB | Reasoning, coding |
| Llama 3.1 70B | ~40GB | 64GB+ | Maximum capability |
Can your laptop run a local LLM?
Minimum for small models (up to about 8B): 8GB RAM (16GB recommended), 10GB free storage (50GB for flexibility), any processor from the last five years. A GPU helps but is not required.
| Example models | Hardware Needed | Impact | |
|---|---|---|---|
| 3-8B parameters | Phi-4-mini, Mistral 7B, Llama 3.1 8B | 8-16GB RAM, no GPU needed | Most business laptops |
| 13-32B parameters | Qwen 2.5 14B/32B, DeepSeek 32B | 32GB RAM or a capable GPU | High-end laptops |
| 70B parameters | Llama 3.1 70B | 64GB+ RAM or large GPU | Workstations and servers |
- Windows: most business laptops from 2022 onward with 16GB RAM handle 7 to 8B models comfortably.
- Mac: Apple Silicon (M1 to M4) is well suited because of unified memory. 16GB is a good minimum.
- Linux: same RAM guidance; NVIDIA GPUs with CUDA give the best acceleration.
A 2019 laptop with 8GB RAM and no GPU will struggle with anything beyond the smallest models.

You now have a private assistant on your laptop.
What can you use offline AI for at work?
- Email drafting: "Write a polite email declining a meeting this week but offering next week."
- Document summaries: "Summarise this document in 5 key points." Break long documents into chunks; many local setups use 8K to 32K token context windows.
- Meeting notes: "Turn these notes into attendees, decisions, action items with owners, and next steps."
- Formula and code help: "Explain this Excel formula and suggest improvements."
- Data analysis scripts: "Write a Python script to total monthly sales by region from this CSV."
- Translation: Qwen and Mistral models handle common languages well; check important translations with a fluent speaker.
- Report drafts: "Draft an executive summary from these points."
How does local AI compare with cloud AI?
| Local AI | Cloud AI (frontier models) | Impact | |
|---|---|---|---|
| Privacy | Data stays on the device | Data sent to provider servers | Local wins |
| Cost model | Hardware you already own | Per-user subscription or per-token fees | Depends on volume |
| Speed | Slower on laptops | Fast | Cloud wins |
| Capability | Good for routine tasks | Stronger reasoning and writing | Cloud wins |
| Availability | Works offline | Needs internet, subject to outages | Local wins |
| Context length | Typically shorter | Much longer | Cloud wins |
Use local AI for first drafts, formatting, meeting notes, formula and code help, and anything involving sensitive data.
Use approved cloud AI for complex multi-step analysis, very long documents and tasks that need current information, where policy allows.
For organisation-wide use, a middle path is private AI infrastructure: larger open models running on your own servers or your cloud in Australia, shared securely across teams. Our data sovereignty guide explains the options.
How should you approach IT about local AI?
Do not say: "ChatGPT is blocked and I need it unblocked."
Do say: "Can we assess local AI tools that run entirely offline, with no data leaving the device, against our security requirements?"
Points for IT:
- No network calls once models are downloaded.
- No API keys to manage.
- Works in air-gapped environments.
- Ollama, Jan and GPT4All are open source and auditable.
- Uses existing hardware.
Your organisation will still need a software approval process, an acceptable use policy for AI, rules on what data may be processed, and a list of approved models. A sensible start is a small pilot group with defined use cases for 30 days, written guidelines, approved models only, and feedback before expanding.
- Data leaving the deviceNone after model download
- Per-use feesNone
- Setup time for one laptopUnder an hour
- Works without internetYes
What should you do this week?
- Install LM Studio or Ollama.
- Download Llama 3.1 8B or Mistral 7B (or Phi-4-mini on older hardware).
- Try summarising a non-sensitive document or drafting an email.
- Compare a couple of models on your real tasks.
- Talk to IT about formalising approved use.
