Attention Mechanism (GQA)

Query:  [5 heads × 128 dim] = 640
Key:    [1 heads × 128 dim] = 128
Value:  [1 heads × 128 dim] = 128

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: 640 × 1920
- W_up:   640 × 1920
- W_down: 1920 × 640
- SiLU(x) = x · sigmoid(x)
- ⊙ = element-wise multiplication

💬 Format Chat & Prompt Engineering

📝 Chat Template

Model mendukung format chat standar untuk conversational AI:

# 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

    {"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

# Rule of thumb untuk 550.10M model
# GPU Memory → Batch size per device

if gpu_memory >= 80:  # A100 80GB
    batch_size = 29
    gradient_accumulation = 1
elif gpu_memory >= 40:  # A100 40GB
    batch_size = 14
    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

# Recommended untuk 550.10M model
learning_rate = 0.0003635722268513854  # 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 = 0.0003635722268513854
# Untuk batch size 512: LR = 5.14e-04

Gradient Clipping

# 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

# Tips untuk stable training:

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

🔧 Troubleshooting

Out of Memory (OOM)

# 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 = 2048  # Start dengan ini

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

Slow Training

# 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

# 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()
