Overview

Paterikon-SFT-v1 is the first instruction-tuned checkpoint derived from Paterikon-3B. It was fine-tuned with supervised fine-tuning (SFT) on ~140M tokens of synthetically-generated Orthodox Christian Q&A pairs covering theology, spiritual life, Church Fathers, liturgy, and pastoral guidance.

The base model (Paterikon-3B) already had patristic domain fluency from continued pre-training on 116M tokens of Church Father writings. This SFT pass teaches it to answer questions in a pastoral Orthodox voice with theological accuracy.

Quick Start

python
Copy code
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "jayfurzy/paterikon-sft-v1"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

messages = [
    {"role": "system", "content": "You are an Orthodox Christian theologian, answering in the spirit of the Holy Fathers."},
    {"role": "user", "content": "What does St. John Chrysostom teach about wealth and poverty?"},
]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.7, do_sample=True)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Intended Use

• Orthodox theological Q&A
• Pastoral guidance and spiritual counsel
• Patristic text generation and completion
• Educational tool for Orthodox Christian studies
• Base for further fine-tuning (RLHF, DPO)

Limitations

• May confabulate on specific factual questions about Church history dates, canon law, or exact patristic citations
• Not a substitute for a spiritual father or priest
• Reflects the synthetic data distribution — heavy on Russian Orthodox sources
• Temperature > 0.8 may produce theologically inconsistent outputs
