**JujutsuKaiserver** is a Retrieval-Augmented Generation (RAG) model built for one purpose:
|
||||||
|
to answer anything and everything about the **Jujutsu Kaisen** universe — with canon-backed accuracy, zero hallucination tolerance, and the confidence of Unlimited Void.

## ⚡ What It Does
|
||||||
|
|
||||||
|
Ask it anything. Techniques. Domains. Arcs. Hidden lore. Character relationships. Cursed Energy mechanics. It retrieves the most relevant passages from a **200+ page wiki corpus**, feeds them into a fine-tuned **Qwen2.5-1.5B-Instruct** backbone, and gives you a clean, grounded answer — not a guess.
|
||||||
|
|
||||||
|
| Ask This | Get This |
|
||||||
|
|----------|----------|
|
||||||
|
| *"What is Sukuna's Shrine?"* | Full technique breakdown with canon context |
|
||||||
|
| *"How does Mahito's Idle Transfiguration work?"* | Soul-level mechanics explained accurately |
|
||||||
|
| *"What happened in the Shibuya Incident?"* | Arc summary backed by wiki chunks |
|
||||||
|
| *"Who is the strongest Grade 1 sorcerer?"* | Ranked answer with sourced reasoning |

### Model Composition
|
||||||
|
|
||||||
|
| Component | Details |
|
||||||
|
|-----------|---------|
|
||||||
|
| 🤖 **Base LLM** | `Qwen/Qwen2.5-1.5B-Instruct` (4-bit quantized) |
|
||||||
|
| 🔢 **Embeddings** | `sentence-transformers/all-MiniLM-L6-v2` |
|
||||||
|
| 📦 **Vector Store** | FAISS — `jjk_index.faiss` |
|
||||||
|
| 📖 **Knowledge Base** | 120+ cleaned JJK Fandom Wiki articles (`chunks.txt`) |
|
||||||
|
| 🔧 **Pipeline** | Custom `JujutsuKaiserver` class with Qwen chat template |
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 🚀 Quick Start
|
||||||
|
|
||||||
|
```python
|
||||||
|
from huggingface_hub import snapshot_download
|
||||||
|
|
||||||
|
model_dir = snapshot_download("TinyModels/JujutsuKaiserver")
|
||||||
|
|
||||||
|
import sys
|
||||||
|
sys.path.insert(0, model_dir)
|
||||||
|
from pipeline import JujutsuKaiserver
|
||||||
|
|
||||||
|
bot = JujutsuKaiserver(model_dir=model_dir)
|
||||||
|
|
||||||
|
# Ask anything
|
||||||
|
print(bot.ask("What is Gojo's Domain Expansion called?"))
|
||||||
|
# → "Infinite Void (無量空処). It..."
|
||||||
|
```
|
||||||
|
|
||||||
|
> ⚠️ **Requirements**: `bitsandbytes`, GPU with **≥6 GB VRAM**. CPU inference works but is slow.
|
||||||
|
|
||||||
|
### Install Dependencies
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pip install transformers bitsandbytes faiss-cpu sentence-transformers huggingface_hub
|
||||||
|
```
|
||||||
|

## 🖥️ Gradio Demo (Optional)
|
||||||
|
|
||||||
|
Spin up a local chat UI in seconds:
|
||||||
|
|
||||||
|
```python
|
||||||
|
import gradio as gr
|
||||||
|
from pipeline import JujutsuKaiserver
|
||||||
|
|
||||||
|
bot = JujutsuKaiserver(model_dir="<path_to_downloaded_model>")
|
||||||
|
|
||||||
|
def chat(message, history):
|
||||||
|
return bot.ask(message)
|
||||||
|
|
||||||
|
gr.ChatInterface(
|
||||||
|
fn=chat,
|
||||||
|
title="🟣 JujutsuKaiserver",
|
||||||
|
description="Ask anything about the JJK universe."
|
||||||
|
).launch()
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## ✨ Features
|
||||||
|
|
||||||
|
- 🔍 **Factual Q&A** — Every answer is grounded in retrieved wiki content, not imagination
|
||||||
|
- 🚫 **Hallucination Guard** — Model is prompted to say *"I don't know"* when context is insufficient
|
||||||
|
- 📚 **Deep Coverage** — 200+ wiki pages: characters, techniques, domains, arcs, lore
|
||||||
|
- ⚡ **T4-Friendly** — 4-bit quantization means it runs on free Colab tiers
|
||||||
|
- 🤖 **Gradio Ready** — One-script local demo included out of the box
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## ⚠️ Known Limitations
|
||||||
|
|
||||||
|
- **Recent chapters** beyond the scraping date may not be indexed yet
|
||||||
|
- **Ambiguous context** can still occasionally produce imperfect answers — being addressed via a feedback loop
|
||||||
|
- **Roleplay mode** is possible with a custom system prompt, but this version is optimized for factual retrieval
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 🔮 Roadmap
|
||||||
|
|
||||||
|
- [ ] **Live Feedback Flagging** — 👍/👎 votes from the Gradio Space feed a correction dataset automatically
|
||||||
|
- [ ] **Self-Correcting Pipeline** — Weekly DPO fine-tuning on flagged examples + FAISS index refresh
|
||||||
|
- [ ] **Expanded KB** — Episode transcripts, manga panels text, community lore
|
||||||
|
- [ ] **Streaming Support** — Token-by-token output for snappier UX

# CrossEncoder based on cross-encoder/ms-marco-MiniLM-L6-v2
|
||||||
|
|
||||||
|
This is a [Cross Encoder](https://www.sbert.net/docs/cross_encoder/usage/usage.html) model finetuned from [cross-encoder/ms-marco-MiniLM-L6-v2](https://huggingface.co/cross-encoder/ms-marco-MiniLM-L6-v2) using the [sentence-transformers](https://www.SBERT.net) library. It computes scores for pairs of texts, which can be used for text reranking and semantic search.

### Full Model Architecture
|
||||||
|
|
||||||
|
```
|
||||||
|
CrossEncoder(
|
||||||
|
(0): Transformer({'transformer_task': 'sequence-classification', 'modality_config': {'text': {'method': 'forward', 'method_output_name': 'logits'}}, 'module_output_name': 'scores', 'architecture': 'BertForSequenceClassification'})
|
||||||
|
)
|

|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
### Direct Usage (Sentence Transformers)
|
||||||
|
|
||||||
|
First install the Sentence Transformers library:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pip install -U sentence-transformers
|
||||||
|
```
|
||||||
|
|
||||||
|
Then you can load this model and run inference.
|
||||||
|
```python
|
||||||
|
from sentence_transformers import CrossEncoder
|
||||||
|
|
||||||
|
# Download from the 🤗 Hub
|
||||||
|
model = CrossEncoder("cross_encoder_model_id")
|
||||||
|
# Get scores for pairs of inputs
|
||||||
|
pairs = [
|
||||||
|
['How many calories in an egg', 'There are on average between 55 and 80 calories in an egg depending on its size.'],
|
||||||
|
['How many calories in an egg', 'Egg whites are very low in calories, have no fat, no cholesterol, and are loaded with protein.'],
|
||||||
|
['How many calories in an egg', 'Most of the calories in an egg come from the yellow yolk in the center.'],
|
||||||
|
]
|
||||||
|
scores = model.predict(pairs)
|
||||||
|
print(scores)
|
||||||
|
# [ 9.9541 -2.0108 0.9186]
|
||||||
|
|
||||||
|
# Or rank different texts based on similarity to a single text
|
||||||
|
ranks = model.rank(
|
||||||
|
'How many calories in an egg',
|
||||||
|
[
|
||||||
|
'There are on average between 55 and 80 calories in an egg depending on its size.',
|
||||||
|
'Egg whites are very low in calories, have no fat, no cholesterol, and are loaded with protein.',
|
||||||
|
'Most of the calories in an egg come from the yellow yolk in the center.',
|
||||||
|
]
|
||||||
|
)
|
||||||
|
# [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...]
|
||||||
|
```
