LLMSharp Tokenizers

build and test CodeQL

  • LLMSharp.Anthropic.Tokenizer : Unofficial implementation of tokenizer for Anthropic claude in dotnet. Install this nuget package for Encoding using Claude Tokenizer.
  • LLMSharp.OpenAi.Tokenizer : Unofficial implementation of tokenizer for GPT-3.5/GPT-4 models in dotnet. Install this nuget package for Encoding using GPT Chat Completions Model Tokenizer.

Usage

  • Install the latest version of nuget package
dotnet add package LLMSharp.Anthropic.Tokenizer

dotnet add package LLMSharp.OpenAi.Tokenizer
  • Create an instance of the tokenizer
// Claude Tokenizer
using LLMSharp.Anthropic.Tokenizer;

var tokenizer = new ClaudeTokenizer();


// OpenAi ChatCompletion Models Tokenizer
using LLMSharp.OpenAi.Tokenizer;

var tokenizer = new OpenAiChatCompletionsTokenizer();
  • Encode : tokenizes a given text, this is the default implementation that throws an exception if the text contains any special tokens
var encodedTokens = tokenizer.Encode("hello world");
  • CountTokens : count tokens in a given text, this is the default implementation that throws an exception if the text contains any special tokens
var tokenCount = tokenizer.CountTokens("hello world");
  • EncodeWithSpecialTokens : tokenizes a given text, including all or specific special tokens
// passing 'null' for allowedSpecial , will help tokenize all special tokens
var encodedBytes = tokenizer.EncodeWithSpecialTokens(
    text:"<META_START>some data<META_END>",
    allowedSpecial: null,
    disallowedSpecial: null);


// passing an array of strings for allowedSpecial , will help tokenize only those special tokens
// any other special tokens found in the text will throw an exception
var encodedBytes = tokenizer.EncodeWithSpecialTokens(
    text:"<META_START>some data<META_END>",
    allowedSpecial: new string[]{"<META_START>", "<META_END>"},
    disallowedSpecial: null);
  • CountWithSpecialTokens : count tokens in a given text, including all or specific special tokens
var tokenCount = tokenizer.CountWithSpecialTokens(
    text:"<META_START>some data<META_END>",
    allowedSpecial: new string[]{"<META_START>", "<META_END>"},
    disallowedSpecial: null);
