Running AI on Your PC? Understanding Local LLM

Having AI on your PC means you can use it freely anytime, anywhere. However, ChatGPT requires an internet connection to use AI functionality.

Worried About ChatGPT API Costs or Limitations?

That's understandable. Using AI through APIs can incur costs, and there may be usage limitations or network requirements. If you're sensitive to these costs, want to work offline, or are concerned about data privacy, there are alternatives.

The alternative is 'Local LLM'. By running an LLM locally, you can use AI offline directly on your PC. This makes it possible to process sensitive data, work offline, or avoid API costs.
