⚠️ 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 (Kaiming/Xavier init)
🟡 Untuk riset & eksperimen - Arsitektur sudah siap, tinggal train
🟢 Production-ready architecture - Teruji dan optimal

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

🎯 Apa yang Bisa Dilakukan?

✅ Bisa	❌ Belum Bisa
Load model architecture	Generate teks bermakna
Test forward pass	Menjawab pertanyaan

📋 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 komputasi, skalabilitas, dan performa tinggi.

📖 Tentang Project Caca

Caca adalah 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. Ini proyek eksplorasi, jadi kalau gagal ya bagian dari proses belajar. Kalau berhasil, itu bonus.

— Lyon, Creator

Attention Mechanism (GQA)

Query:  [5 heads × 32 dim] = 160
Key:    [1 heads × 32 dim] = 32
Value:  [1 heads × 32 dim] = 32

Grouped Query Attention:
- Setiap 5 query heads berbagi 1 KV head
- Memory KV cache: 80% lebih kecil dari Multi-Head Attention
- Kualitas mendekati MHA, speed mendekati MQA

Feed-Forward Network (SwiGLU)

FFN(x) = (SiLU(xW_gate) ⊙ xW_up) W_down

Where:
- W_gate: 160 × 448
- W_up:   160 × 448
- W_down: 448 × 160
- SiLU(x) = x · sigmoid(x)
- ⊙ = element-wise multiplication

💬 Format Chat & Prompt Engineering

📝 Chat Template

Model mendukung format chat standar untuk conversational AI:

python

# Format chat template bawaan
chat_template = """
{% for message in messages %}
{% if message['role'] == 'system' %}
System: {{ message['content'] }}

{% elif message['role'] == 'user' %}
User: {{ message['content'] }}

{% elif message['role'] == 'assistant' %}
Assistant: {{ message['content'] }}

{% endif %}
{% endfor %}
{% if add_generation_prompt %}Assistant:{% endif %}
"""

# Contoh penggunaan
messages = [
    {"role": "system", "content": "Kamu adalah asisten AI yang membantu dan ramah."},
    {"role": "user", "content": "Jelaskan tentang fotosintesis"},
    {"role": "assistant", "content": "Fotosintesis adalah proses di mana tumbuhan mengubah cahaya matahari menjadi energi kimia..."},
    {"role": "user", "content": "Apa manfaatnya bagi manusia?"},
]

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

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

🛠️ Development & Training Tips

Optimal Batch Size

python

# Rule of thumb untuk 2.94M model
# GPU Memory → Batch size per device

if gpu_memory >= 80:  # A100 80GB
    batch_size = 5439
    gradient_accumulation = 1
elif gpu_memory >= 40:  # A100 40GB
    batch_size = 2719
    gradient_accumulation = 1
elif gpu_memory >= 24:  # RTX 3090/4090
    batch_size = 1
    gradient_accumulation = 1

# Effective batch size = batch_size × gradient_accumulation × num_gpus

Learning Rate Scheduling

python

# Recommended untuk 2.94M model
learning_rate = 0.0005  # Base LR
warmup_ratio = 0.05  # 5% of total steps
lr_scheduler = "cosine"  # atau "linear"

# Learning rate scaling rule:
# LR ∝ sqrt(batch_size)
# Untuk batch size 256: LR = 0.0005
# Untuk batch size 512: LR = 7.07e-04

Gradient Clipping

python

# Prevent gradient explosion
max_grad_norm = 1.0  # Clip at 1.0

# Monitor gradients
from torch.nn.utils import clip_grad_norm_

grad_norm = clip_grad_norm_(model.parameters(), max_grad_norm)
if grad_norm > 10.0:
    print(f"⚠️ High gradient norm: {grad_norm:.2f}")

Training Stability

python

# Tips untuk stable training:

**Warmup**: Mulai dengan LR rendah
**Gradient Checkpointing**: Kurangi memory footprint
**Mixed Precision**: Gunakan BF16 jika tersedia (lebih stable dari FP16)
**Batch Size**: Start small, increase gradually
**Monitor**: Track loss, perplexity, gradient norms

🔧 Troubleshooting

Out of Memory (OOM)

python

# Solusi OOM saat training:

✅ 1. Enable gradient checkpointing
model.gradient_checkpointing_enable()

✅ 2. Reduce batch size
per_device_train_batch_size = 1

✅ 3. Increase gradient accumulation
gradient_accumulation_steps = 32

✅ 4. Use quantization
load_in_8bit = True  # atau load_in_4bit

✅ 5. Reduce sequence length
max_length = 512  # Start dengan ini

✅ 6. CPU offloading (jika perlu)
device_map = "auto"
offload_folder = "offload"

Slow Training

python

# Optimasi kecepatan training:

✅ 1. Flash Attention
config.use_flash_attn = True  # 2-3x speedup

✅ 2. Compile model (PyTorch 2.0+)
model = torch.compile(model, mode="reduce-overhead")

✅ 3. DataLoader optimization
dataloader = DataLoader(
    dataset,
    batch_size=batch_size,
    num_workers=4,  # Parallel data loading
    pin_memory=True,  # Faster GPU transfer
    prefetch_factor=2
)

✅ 4. Mixed precision
use_fp16 = True  # atau bf16

✅ 5. Optimize communication (multi-GPU)
find_unused_parameters = False
gradient_as_bucket_view = True

NaN Loss

python

# Jika loss menjadi NaN:

✅ 1. Reduce learning rate
learning_rate = learning_rate * 0.1

✅ 2. Check gradient norms
clip_grad_norm_(model.parameters(), 1.0)

✅ 3. Use BF16 instead of FP16
torch_dtype = torch.bfloat16  # Lebih stable

✅ 4. Add epsilon to RMSNorm
rms_norm_eps = 1e-5  # Increase jika perlu

✅ 5. Check data
# Pastikan tidak ada inf/nan di dataset
assert not torch.isnan(input_ids).any()
assert not torch.isinf(attention_mask).any()
