Massive Language Fashions (LLMs) have reworked how we work together with AI, however utilizing them usually requires sending your knowledge to cloud providers like OpenAI’s ChatGPT. For these involved with privateness, working in environments with restricted web entry, or just eager to keep away from subscription prices, working LLMs regionally is a horny various.
With instruments like Ollama, you’ll be able to run giant language fashions immediately by yourself {hardware}, sustaining full management over your knowledge.

Downloading and Putting in Ollama
To get began with Ollama, you’ll have to obtain and set up it in your system.
First off, go to the official Ollama web site at https://ollama.com/obtain and choose your working system. I’m utilizing Home windows, so I’ll be overlaying that. It’s very simple for all working techniques although, so no worries!

You possibly can test if the service is working appropriately by opening http://localhost:11434 in your net browser. For those who see a response, you’re good to go!
Your First Chat
Now that Ollama is put in, it’s time to obtain an LLM and begin a dialog.
Be aware: By default, Ollama fashions are saved in your C-drive on Home windows and on your private home listing on Linux and macOS. If you wish to use a special listing, you’ll be able to set the OLLAMA_DATA_PATH setting variable to level to the specified location. That is particularly helpful when you have restricted disk house in your drive.
To do that, use the command setx OLLAMA_DATA_PATH "path/to/your/listing" on Home windows or export OLLAMA_DATA_PATH="path/to/your/listing" on Linux and macOS.

Do you wish to know something extra about Brussels?
You possibly can proceed the dialog by including extra questions or statements. To exit the chat, sort /bye or press Ctrl+D.
Congratulations! You’ve simply had your first dialog with a regionally working LLM.
The place to Discover Extra Fashions?
Whereas Gemma 3 may work effectively for you, there are lots of different fashions obtainable on the market. Some fashions are higher for coding for instance, whereas others are higher for dialog.
Official Ollama Fashions
The primary cease for Ollama fashions is the official Ollama library.
The library comprises a variety of fashions, together with chat fashions, coding fashions, and extra. The fashions get up to date nearly every day, so be certain that to test again typically.
To obtain and run any of those fashions you’re keen on, test the directions on the mannequin web page.
For instance, you may wish to strive a distilled deepseek-r1 mannequin. To open the mannequin web page, click on on the mannequin identify within the library.
You’ll now see the totally different sizes obtainable for this mannequin (1), together with the command to run it (2) and the used parameters (3).
Relying in your system, you’ll be able to select a smaller or a smaller variant with the dropdown on the left. If in case you have 16GB or extra VRAM and wish to experiment with a bigger mannequin, you’ll be able to select the 14B variant. Deciding on 14b within the dropdown will change the command subsequent to it as effectively.
Select a dimension you wish to attempt to copy the command to your clipboard. Subsequent, paste it right into a terminal or command immediate to obtain and run the mannequin. I went with the 8b variant for this instance, so I ran the next command:
ollama run deepseek-r1:8b
Identical to with Gemma 3, you’ll see a progress indicator because the mannequin downloads. As soon as it’s prepared, you’ll see a >>> Ship a message immediate within the terminal.
To check if the mannequin works as anticipated, ask a query and it’s best to get a response. I requested the identical query as earlier than:
>>> What's the capital of Belgium?
