toklen
Count tokens with a model's real Hugging Face tokenizer. Prints an integer.
npx toklen openai-community/gpt2 "hello world" # 2
uvx toklen openai-community/gpt2 "hello world" # 2
Both commands always print the same number. Node uses
@huggingface/tokenizers,
Python uses the Rust tokenizers bindings. One
dependency each, no transformers, no PyTorch.
