Frequently asked questions
What does 'on-device AI' mean, and how does it differ from cloud-based AI?
On-device AI runs AI models directly on your local computer or phone without sending data to external servers, ensuring complete privacy and allowing offline operation. Cloud-based AI like ChatGPT processes data on remote servers, offering greater processing power but requiring internet connectivity and trusting the provider with your data.
Can I use on-device AI tools without technical knowledge?
Yes. Tools like LM Studio, GPT4All and Solair AI offer graphical interfaces designed for non-technical users. However, some tools like Ollama require command-line familiarity. Start with LM Studio or GPT4All if you prefer avoiding the terminal.
What are the hardware requirements for running on-device AI locally?
Minimum requirements are 4GB RAM and modern CPU, though 8GB+ is recommended. GPU acceleration (NVIDIA, AMD or Apple Silicon) speeds up inference significantly. Tools like GPT4All and Jan work on CPU-only systems but run slower than GPU-accelerated alternatives.
