This implementation aims for maximum performance, especially in the token count operation.
There's also a benchmark console app here for easy tracking of this.
We will be happy to accept any PR.

Implemented encodings

  • cl100k_base
  • r50k_base
  • p50k_base
  • p50k_edit

Usage

var encoding = Tiktoken.Encoding.ForModel("gpt-4");
var tokens = encoding.Encode("hello world"); // [15339, 1917]
var text = encoding.Decode(tokens); // hello world
var numberOfTokens = encoding.CountTokens(text); // 2
var stringTokens = encoding.Explore(text); // ["hello", " world"]

var encoding = Tiktoken.Encoding.Get(Encodings.P50KBase);
var tokens = encoding.Encode("hello world"); // [31373, 995]
var text = encoding.Decode(tokens); // hello world
