-## Token Counting
-
----
-
-By using the `count_tokens` method, you can estimate the billing for a given request.
-
-```python
-from ai21.tokenizers import get_tokenizer
-
-tokenizer = get_tokenizer(name="jamba-tokenizer")
-total_tokens = tokenizer.count_tokens(text="some text")  # returns int
-print(total_tokens)
-```
-
-### Async Usage
-
-```python
-from ai21.tokenizers import get_async_tokenizer
-
-## Your async function code
-#...
-tokenizer = await get_async_tokenizer(name="jamba-tokenizer")
-total_tokens = await tokenizer.count_tokens(text="some text")  # returns int
-print(total_tokens)
-```
-
-Available tokenizers are:
-
-- `jamba-tokenizer`
-- `j2-tokenizer`
-
-For more information on AI21 Tokenizers, see the [documentation](https://github.com/AI21Labs/ai21-tokenizer).
