d-matrix/opt

This is a d-Matrix functional reference of the opt model family, with the following revisions:

• facebook/opt-125m
• facebook/opt-350m
• facebook/opt-1.3b
• facebook/opt-2.7b
• facebook/opt-6.7b

The reference provides the following functional configurations:

Configuration	Explanation
BASELINE	a reference functionally equivalent to the original model
BASIC	all linear algebraic operands quantized to BFP16-64, and all other operations transformed to approximated kernel simulations

Usage

Install d-Matrix ML Tools first.

pip install dmx-mltools

The following is an example model and its evaluation.

from mltools.dmx import pipeline

pipe = pipeline(
    task="text-generation",
    model="d-matrix/opt",
    revision="opt-125m",  # see above for other variants
    dmx_config="BASELINE",  # see above for other variants
)

results = pipe.evaluate(
    metric="d-matrix/dmx_perplexity",
    dataset="wikitext",
    dataset_version="wikitext-2-raw-v1",
)

Evaluation results

• perplexity on penn_treebank
