# rgpt > An automated code review tool that uses GPT you can use straight from your terminal. > More information: . - Ask GPT to improve the code with no extra options: `rgpt --i "$(git diff {{path/to/file}})"` - Get a more detailed verbose output from `rgpt` while reviewing the code: `rgpt --v --i "$(git diff {{path/to/file}})"` - Ask GPT to improve the code and limit it to a certain amount of GPT3 tokens: `rgpt --max {{300}} --i "$(git diff {{path/to/file}})"` - Ask GPT for a more unique result using a float value between 0 and 2. (higher = more unique): `rgpt --pres {{1.2}} --i "$(git diff {{path/to/file}})"` - Ask GPT to review your code using a specific model: `rgpt --model {{davinci}} --i "$(git diff {{path/to/file}})"` - Make `rgpt` use a JSON output: `rgpt --json --i "$(git diff {{path/to/file}})"`
