To enter the world of local AI, two names are essential: Ollama, the tool that simplifies everything, and DeepSeek, one of the most powerful models you can use. Together, they form a perfect combination for anyone who wants to experiment with artificial intelligence on their PC, from developers to small business owners.

Ollama: The Simple Bridge to Local AI

Ollama is an open-source tool that makes it incredibly easy to download, set up, and run large language models (LLMs) on your computer. Its philosophy is similar to Docker’s: with a single terminal command, you can launch a complex AI model that would otherwise require complicated installation and configuration. Available for Windows, macOS, and Linux, Ollama handles all the technical complexities, allowing you to focus solely on using artificial intelligence.

DeepSeek: The Power of Programming at Your Fingertips

DeepSeek is a family of open-source AI models, with particular excellence in tasks related to programming and mathematical reasoning. The DeepSeek Coder V2 version, for example, was trained on billions of lines of code and supports over 338 programming languages, offering performance comparable to paid models like GPT-4 Turbo for specific tasks. Thanks to Ollama, running a powerful model like DeepSeek on your PC becomes an operation accessible to everyone, no longer exclusive to researchers with specialized hardware.

Practical Guide: Installing Ollama and DeepSeek on Your PC

Running an advanced artificial intelligence on your own computer is easier than you think. It only takes a few steps to install Ollama and launch a model like DeepSeek. This guide will show you how, focusing on the essential requirements and commands to get started right away.

System Requirements

Before you begin, it’s important to check that your PC has the necessary resources. Although it’s possible to run smaller models on modest hardware, for a smooth experience with powerful models like DeepSeek, the following are recommended:

• RAM: At least 16 GB. For larger models, 32 GB is ideal.
• Disk Space: Models can take up several gigabytes, so make sure you have at least 20-50 GB free.
• GPU (Graphics Card): It’s not mandatory, but a dedicated GPU (NVIDIA or AMD) with at least 8 GB of VRAM will significantly speed up performance. Without a compatible GPU, Ollama will use the CPU, but responses will be slower.

Installing Ollama

Installing Ollama is a quick and straightforward process. Follow these simple steps:

1. Visit the official website ollama.com and download the installer for your operating system (Windows, macOS, or Linux).
2. Run the downloaded file and follow the on-screen instructions. The installation will set up everything needed to run models from the command line.
3. Once completed, Ollama will be running in the background, ready to receive commands.

Launching DeepSeek with a Simple Command

With Ollama installed, launching DeepSeek is a matter of a single command. Open your terminal (or Command Prompt on Windows) and type:

ollama run deepseek-coder-v2

The first time you run this command, Ollama will automatically download the DeepSeek Coder V2 model (this may take a few minutes, depending on your connection). Once the download is complete, a prompt will appear where you can start chatting directly with the AI. All conversations will take place entirely on your computer, securely and privately.

Beyond Theory: Practical Use Cases in Italy

Local artificial intelligence is not just a technical exercise, but a practical tool with concrete applications in the Italian economic and cultural fabric. From small artisan businesses to software developers, the possibilities are immense and align perfectly with a market that, although lagging in adoption by SMEs, shows enormous growth potential.

The implementation of artificial intelligence is not exclusive to large companies: for Italian small and medium-sized enterprises (SMEs), it also represents an extraordinary opportunity to improve operational efficiency and competitiveness.

• Developers and IT professionals: They can use DeepSeek Coder to generate code, debug, or learn new programming languages without sending proprietary code to external servers. This ensures maximum confidentiality on projects, a crucial aspect for consulting and custom software development. For those working with data, the privacy offered by local chatbots is an invaluable advantage.
• Small and Medium-Sized Enterprises (SMEs): An artisan company can use a local model to create product descriptions for e-commerce, write draft emails for customers, or translate communications, all while maintaining full control over its business data. This combines the Italian tradition of "know-how" with digital innovation, optimizing processes without depending on expensive external services.
• Students and researchers: Offline AI is a powerful ally for summarizing academic articles, analyzing texts, or preparing study materials without needing an internet connection. This not only ensures privacy but also the ability to work anywhere, promoting a more flexible and autonomous approach to studying.

Pros and Cons of Local AI: My Experience

After thoroughly testing Ollama and several models like DeepSeek, I can confirm that the experience of having a personal AI on your computer is as powerful as it is enlightening. The feeling of control is priceless: knowing that every interaction remains private, safe from prying eyes and external training algorithms, is a huge advantage. The responses, once the model is loaded into memory, are almost instantaneous, eliminating the network latency typical of cloud services. It’s an experience that empowers and brings the user closer to the technology.

Personally, the biggest advantage is freedom. The freedom to experiment with different models, to customize them, and to use them without worrying about hidden costs or the privacy of my data. It’s a return to controlling one’s own technology.

However, it’s not a path without obstacles. The main hurdle is hardware: to get decent performance, especially with large models, you need a computer with a good amount of RAM and, ideally, a modern GPU. Without it, text generation can be slow. Furthermore, unlike cloud solutions like those described in the comparison between ChatGPT, Gemini, and Copilot, local models do not update automatically. It’s up to the user to download new versions to benefit from the latest improvements. Finally, the initial setup, although simplified by Ollama, might still be challenging for those unfamiliar with the command line.

Conclusions

Local artificial intelligence, made accessible by tools like Ollama and powerful models like DeepSeek, represents a significant shift in how we interact with technology. It is no longer a luxury for a few, but a concrete resource for anyone who wants to harness the power of AI without compromising the privacy and control of their data.
