ai think model to remove the think tag print

2025-03-19

To remove the <think> tags and their contents from a string using JavaScript and regular expressions, you can use the following code:

function removeThinkTags(input) {
    // Regular expression to match <think> tags and their contents
    const regex = /<think>.*?<\/think>/gs;

    // Replace matched tags with an empty string
    const result = input.replace(regex, '');

    return result;
}

// Example usage
const text = "Okay, the user wants me to translate \"File Upload\" into Chinese. Let me think... I know that \"file\" is commonly </think> ; 删除think标签语句";
const cleanedText = removeThinkTags(text);

console.log(cleanedText);

Explanation:

  • The regular expression /<think>.*?<\/think>/gs is used to match the <think> tags and their contents.
    • <think> matches the opening tag.
    • .*? matches any character (.) zero or more times (*), but as few times as possible (?), making it non-greedy.
    • <\/think> matches the closing tag.
    • The g flag stands for global, meaning it will match all occurrences in the string.
    • The s flag stands for dotAll, allowing . to match newline characters as well.
  • The replace method is used to replace the matched tags and their contents with an empty string, effectively removing them from the input string.
