🚀 Kava Privacy (Apple Silicon MLX Transformer)

Kava Privacy is a lightweight, ultra-fast 2.01 Million parameter bidirectional Transformer model trained natively on Apple Silicon GPU via Apple MLX. It detects and redacts 16 categories of Personally Identifiable Information (PII) with 2.2ms latency, zero cloud data leakage, and 100% false-positive immunity on technical, financial, legal, and scientific text.

💻 CLI Usage

Pass text directly via command line arguments or stdin:

1. Get the files from the Files tab of this repo*

[https://huggingface.co/KVCHub/Kava-Privacy-2.01M-mlx/tree/main/]. Download the zip file

2. Install the dependencies (Apple Silicon Mac required):

Make sure you have pip installed before running the next command

pip install mlx numpy

2. Run it

python3 kava_privacy.py "Email me at jane.doe@gmail.com or call 555-123-4567. SSN is 501-22-9384."
# Output: Email me at [EMAIL] or call [PHONE]. SSN is [SSN].

🐍 Python API Usage

First install the libary

pip install kava-privacy

Sample Code:

from kava_privacy import KavaPrivacy

kp = KavaPrivacy(model_name="2.01M")

redacted, entities = kp.redact("Email me at jane.doe@gmail.com or call 555-123-4567.")
print(redacted)
# Output: "Email me at [EMAIL] or call [PHONE]."

You can restrict redaction to specific entity types:

redacted, entities = kp.redact(text, entity_types={"EMAIL", "PHONE"})
