This package also distributes `tokenizer.json` and `tokenizer_config.json` from these pinned official repositories, both under the MIT license:

- `deepseek-ai/DeepSeek-V4-Pro` revision `0e1a0e5e52aea73055f50fef6f2423db370265b6` (serves `deepseek-v4-flash` and `deepseek-v4-pro`), in `assets/deepseek-v4/`.
- `deepseek-ai/DeepSeek-V4-Flash-Vision-Exp` revision `6821d6ad3681a4b137b066b76094fa82ebd0a380` (serves `deepseek-v4-flash-vision-exp`), in `assets/deepseek-v4-vision-exp/`. This tokenizer is a distinct artifact, not an alias of the V4 Pro tokenizer.

The exact provenance and SHA-256 values are in each directory's `manifest.json`; the upstream license text ships beside the assets. The vision image-token arithmetic is a port of the repository's `inference/image_processor.py` at the same pinned revision.

This package depends on `@huggingface/tokenizers` 0.1.3 under Apache-2.0. Its NPM package carries the dependency license text.

This package depends on `js-yaml` under MIT; its production dependency `argparse` is licensed under Python-2.0. Their NPM packages carry the dependency license texts.

This is an unofficial community package and is not endorsed by DeepSeek.
