Logos v6.1-SFT — Abrahamic Religious Texts Model (Research Alpha)

RESEARCH USE ONLY — This model has known limitations. Not suitable for religious advice, fatwa generation, or authoritative scriptural interpretation.

Overview

Logos v6.1-SFT is a research-grade language model specialized in Abrahamic religious texts across Arabic, Hebrew, Greek, English, Latin, fine-tuned from Qwen2.5-7B-Instruct using QLoRA (r=32, alpha=64).

This version includes:

• Base LM training: 3 epochs on 130K verses (multilingual corpus)
• SFT training: 30K instruction-tuned Q&A samples
• Citation SFT: Additional 1 epoch on 8.2K citation-format examples (experimental)

Model Details

Training Data

Base Corpus (130K verses)

SFT Dataset (30K samples)

Instruction-tuned Q&A pairs covering verse recall, cross-tradition comparison, citation lookup, tafsir explanation, and multilingual text understanding.

Citation SFT Dataset (8.2K samples)

Citation formatting examples for Quran (Surah X:Y), Bible (Book Chapter:Verse), and Talmud (tractate page) formats.

Evaluation (v6.1-SFT, seed=42, greedy)

Known Limitations

• Low citation accuracy (20%) — inconsistent surah:ayah and book:chapter:verse formatting
• Zero exact verse recall — model has not memorized verse text; relies on RAG for verbatim quotes
• Hallucination rate 50% — too high for production factual queries
• Tafsir not learned — needs DPO or targeted tafsir training
• Arabic diacritics — decent F1 but not scholarly-grade tashkeel
• Research only — not intended for religious advice or authoritative interpretation

Usage

Transformers (GPU)

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model = AutoModelForCausalLM.from_pretrained(
    "frostedunicorn/logos-v61-sft",
    torch_dtype=torch.float16,
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("frostedunicorn/logos-v61-sft")

prompt = "Explanation of Surah 1:1 in the Quran:"
messages = [{"role": "user", "content": prompt}]
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=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))
