AI21 Labs Tokenizer

A SentencePiece based tokenizer for production uses with AI21's models

---

Installation

pip

pip install ai21-tokenizer

poetry

poetry add ai21-tokenizer

Usage

Tokenizer Creation

from ai21_tokenizer import Tokenizer

tokenizer = Tokenizer.get_tokenizer()
# Your code here

Another way would be to use our Jurassic model directly:

from ai21_tokenizer import JurassicTokenizer

model_path = "<Path to your vocabs file. This is usually a binary file that end with .model>"
config = {} # "dictionary object of your config.json file"
tokenizer = JurassicTokenizer(model_path=model_path, config=config)

Functions

Encode and Decode

These functions allow you to encode your text to a list of token ids and back to plaintext

text_to_encode = "apple orange banana"
encoded_text = tokenizer.encode(text_to_encode)
print(f"Encoded text: {encoded_text}")

decoded_text = tokenizer.decode(encoded_text)
print(f"Decoded text: {decoded_text}")

What if you had wanted to convert your tokens to ids or vice versa?

tokens = tokenizer.convert_ids_to_tokens(encoded_text)
print(f"IDs corresponds to Tokens: {tokens}")

ids = tokenizer.convert_tokens_to_ids(tokens)
