Saturn-1.5B & Saturn-7B

arXiv

Model Overview

Saturn-1.5B and Saturn-7B are part of the SATURN framework, which utilizes Boolean Satisfiability (SAT) problems to continuously improve language model reasoning through a curriculum learning pipeline.

Model Details

Saturn-1.5B: A 1.5 billion parameter model.
Saturn-7B: A 7 billion parameter model.

Usage

To use these models, simply load them from Hugging Face’s transformers library, as shown below:

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "gtxygyzb/Saturn-7B"  # or "gtxygyzb/Saturn-1.5B"
model = AutoModelForCausalLM.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
