Claude Tokenizer

Claude Tokenizer is a Rust library for tokenizing text using the Anthropic Claude models. It provides functionality to tokenize text and count tokens, which is useful for working with Claude and other large language models.

Features

• Tokenizer for Anthropic's Claude AI models
• tokenize function to convert text into tokens
• count_tokens function to calculate the number of tokens in a given text
• Embedded JSON tokenizer data for offline use
• Built on the tokenizers library for efficient tokenization

Installation

Add this to your Cargo.toml:

[dependencies]
claude_tokenizer = "0.2.0"

Then, run cargo build to build your project.

Usage

Import the claude_tokenizer crate into your Rust project:

use claude_tokenizer;

Then, you can use the tokenize and count_tokens functions:

let text = "Hello, world!";
let tokens = tokenize(text).unwrap();
let token_count = count_tokens(text).unwrap();

println!("Tokens: {}", tokens);
println!("Token count: {}", token_count);
