rcrc-chat-v5-gemma-1b-cpt-sft — Closed-Book RCRC Chatbot

A 1B closed-book chatbot for the Royal Commission for Riyadh City (RCRC). Trained as Path B of the v5 comparison: continued pre-training on raw KB text, then chat SFT on Qwen3-235B-synthesized QA pairs.

Closed-book here means the model answers from baked-in knowledge — there is no retrieval at inference.

Pipeline

google/gemma-3-1b-pt
   ↓  CPT: 3 epochs on cleaned RCRC + Hanifa raw text
perfectPresentation/rcrc-gemma-1b-cpt
   ↓  SFT: 3 epochs on rcrc-qa-v5 (16,761 Qwen-synthesized QA pairs)

python

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

tok = AutoTokenizer.from_pretrained("perfectPresentation/rcrc-chat-v5-gemma-1b-cpt-sft")
model = AutoModelForCausalLM.from_pretrained(
    "perfectPresentation/rcrc-chat-v5-gemma-1b-cpt-sft",
    dtype=torch.bfloat16,

messages = [
    {"role": "system", "content":
        "أنت مساعد للهيئة الملكية لمدينة الرياض. تجيب على استفسارات المستخدمين "
        "عن خدمات وبرامج ومشاريع وأنظمة الهيئة بدقة وأدب."},

Honest evaluation: closed-book vs RAG

On a 50-question internal eval set (RCRC + Hanifa + edge cases), this closed-book model was compared to a sibling RAG pipeline (the v3-rag checkpoint reading retrieved chunks from rcrc-rag-index-v2):

	accuracy	relevance	clarity	wins
RAG (v3-rag + index v2)	3.92	4.08	4.42	34/50
This model (closed-book)	2.64	3.36	3.56	13/50
Ties				3/50

Where closed-book is competitive: dialect responses (Najdi/Hijazi), free-form opinion-style queries.

Where RAG dominates: factual specifics from the Hanifa Urban Code, project details, organizational facts, numerical specs.

For accuracy-sensitive deployments on the RCRC + Hanifa corpus, a RAG pipeline at the same parameter count outperforms this closed-book model by ~1.3 points on average. This model is provided for completeness of the v5 study and for offline / no-retrieval scenarios.

Limitations

1B-scale closed-book recall is brittle on specifics (numbers, exact procedure steps). Verify against rcrc.gov.sa.
Training data was Qwen-synthesized; some questions may carry the synthesizer's biases.
No multi-turn conversational SFT — single-turn QA only.
