### Interactive mode
|
||||
|
||||
If you want a more ChatGPT-like experience, you can run in interactive mode by passing `-i` as a parameter.
|
||||
In this mode, you can always interrupt generation by pressing Ctrl+C and enter one or more lines of text which will be converted into tokens and appended to the current context. You can also specify a *reverse prompt* with the parameter `-r "reverse prompt string"`. This will result in user input being prompted whenever the exact tokens of the reverse prompt string are encountered in the generation. A typical use is to use a prompt which makes LLaMa emulate a chat between multiple users, say Alice and Bob, and pass `-r "Alice:"`.

- Always consider cross-compatibility with other operating systems and architectures
|
||||
- Avoid fancy looking modern STL constructs, use basic `for` loops, avoid templates, keep it simple
|
||||
- There are no strict rules for the code style, but try to follow the patterns in the code (indentation, spaces, etc.). Vertical alignment makes things more readable and easier to batch edit
|

- Clean-up any trailing whitespaces, use 4 spaces indentation, brackets on same line, `void * ptr`, `int & a`
