## ⚠️ PENTING: Model Belum Dilatih (Untrained)

> **PERHATIAN**: Ini adalah model yang **belum melalui proses training**. Bobot model masih dalam kondisi random initialization. Output yang dihasilkan akan **tidak bermakna dan acak**.

**Status Model:**
- 🔴 **Belum dilatih** - Bobot masih random
- 🟡 **Hanya untuk riset** - Eksperimen arsitektur & training
- 🟢 **Siap dilatih** - Arsitektur sudah teruji

Widget di atas hanya menunjukkan **format input yang diharapkan**. Setelah model dilatih dengan dataset yang tepat, format yang sama akan menghasilkan output berkualitas.

## 📋 Deskripsi

**Caca** adalah arsitektur Large Language Model (LLM) generasi terbaru yang menggabungkan berbagai teknik state-of-the-art dalam deep learning. Model ini dirancang dengan fokus pada **efisiensi**, **skalabilitas**, dan **performa tinggi**.

<blockquote style="border-left: 4px solid #4A90E2; padding-left: 16px; margin: 16px 0; color: #555;">
<p><strong>Caca</strong> itu eksperimen open-source Indonesian LLM yang dibuat dari nol secara individual dan bertahap. Bukan kompetitor siapa-siapa, cuma pengen eksplorasi apa yang bisa dilakukan dengan budget terbatas, passion unlimited, dan mindset collaborative. Kalau berguna buat orang lain, alhamdulillah. Kalau enggak, ya tetap fun kok.</p>
<p>Ini proyek eksplorasi, jadi kalau gagal ya bagian dari proses belajar. Kalau berhasil, itu bonus.</p>

    {"role": "user", "content": "Jelaskan tentang fotosintesis"},
    {"role": "assistant", "content": "Fotosintesis adalah proses..."},
    {"role": "user", "content": "Apa manfaatnya bagi manusia?"},
]

# Apply chat template
formatted = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

print(formatted)
# Output:
# System: Kamu adalah asisten AI yang membantu.

## ⚠️ Limitations & Bias

### Keterbatasan

- 🔴 **Untrained**: Model belum dilatih, output random
- 🟡 **No Tokenizer**: Perlu prepare tokenizer sendiri
- 🟡 **No Safety**: Belum ada content filtering/alignment
- 🟠 **Memory Intensive**: Training butuh GPU besar

### Potential Biases

Model ini akan mewarisi bias dari data training yang digunakan. Mohon perhatikan:

- **Bahasa**: Bias terhadap bahasa mayoritas di dataset
- **Kultur**: Bias terhadap perspektif kultur tertentu
- **Gender & Demografis**: Potential stereotypes
- **Faktual**: Bisa generate informasi tidak akurat

**Rekomendasi**: Lakukan evaluation & filtering sebelum deployment.
