pllm.protocols Python API

Protocol components define which parties exchange which protected values and keep baseline masking separate from optional verification. Presence documents API availability, not complete model, security, or deployment coverage; check implementation status before relying on a path.

Research context

Relevant design inputs: Slalom, DASH. PLLM's implementation and evidence claims remain independent.

Python SDK example

The example performs a bounded offline task and checks an observable result. It does not download a checkpoint or contact a provider.

import pllm.protocols as protocols

guarded = protocols.GuardedLinear(max_rows_per_request=128, output_dither_bound=1)
assert guarded.get_params()["max_rows_per_request"] == 128
