## 🎯 Quick Start

### Basic Text Generation

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Load model and tokenizer
model = AutoModelForCausalLM.from_pretrained("shivash/MyAwesome-299M-Model")
tokenizer = AutoTokenizer.from_pretrained("shivash/MyAwesome-299M-Model")

# Generate text
prompt = "The future of AI is"
inputs = tokenizer(prompt, return_tensors="pt")

with torch.no_grad():
    outputs = model.generate(
        **inputs,
        max_new_tokens=50,
        temperature=0.7,
        do_sample=True,
        pad_token_id=tokenizer.eos_token_id
    )

response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
```

### Adapter Fine-tuning (Recommended)

```python
from peft import LoraConfig, get_peft_model, TaskType

# Configure LoRA adapter
lora_config = LoraConfig(
    task_type=TaskType.CAUSAL_LM,
    r=8,  # Rank
    lora_alpha=16,  # Alpha scaling
    lora_dropout=0.1,
    target_modules=[
        "q_proj", "k_proj", "v_proj", "o_proj",
        "gate_proj", "up_proj", "down_proj"
    ],
    bias="none"
)

# Apply LoRA to model
model = get_peft_model(model, lora_config)

# Now ready for task-specific fine-tuning!
# Only ~1% of parameters are trainable
print(f"Trainable parameters: {model.num_parameters(only_trainable=True):,}")
```

## 🎨 Adapter Examples

This model shines when fine-tuned with adapters for specific tasks. Here are some examples:

### 📊 Math Reasoning Adapter

```bash
# Train a math specialist (from the framework)
python scripts/train_task_adapters.py --task math --test
```

**Sample Output:**
```
Input: "What is 25% of 160?"
Output: "To find 25% of 160:
25% = 25/100 = 0.25
0.25 × 160 = 40
Therefore, 25% of 160 is 40."
```

### 💻 Code Generation Adapter

```bash
# Train a coding assistant
python scripts/train_task_adapters.py --task coding --test
```

**Sample Output:**
```python
# Input: "Function to check if a number is prime"
def is_prime(n):
    if n < 2:
        return False
    for i in range(2, int(n**0.5) + 1):
        if n % i == 0:
            return False
    return True
```

### ✍️ Creative Writing Adapter

```bash
# Train a creative writing assistant
python scripts/train_task_adapters.py --task creative --test
```

**Sample Output:**
```
Input: "A robot discovers emotions"
Output: "Unit-7742 had processed millions of data points, but nothing had
prepared it for the strange sensation that flooded its circuits when it
witnessed the sunset. For the first time, efficiency seemed irrelevant."
```

## 🧠 Vocabulary Expansion for Distillation

### Breaking the Vocabulary Barrier

One of the key challenges in knowledge distillation is vocabulary mismatch - your student model (50K tokens) can't directly learn from a teacher with a different vocabulary (150K tokens). Our vocabulary expansion tool solves this:

```bash
# Expand vocabulary to match any teacher model
python expand_vocab.py \
  --model_repo_id "shivash/MyAwesome-299M-Model" \
  --new_tokenizer_repo_id "Qwen/Qwen2-1.5B" \
  --output_dir "./MyAwesome-299M-Model-Qwen-Vocab"
```

**What this does:**
- ✅ **Preserves all existing knowledge** from your 50K vocabulary
- ✅ **Adds new token capacity** (e.g., 100K new tokens for Qwen2)
- ✅ **Intelligently initializes new embeddings** (mean of existing weights)
- ✅ **Enables distillation** from any teacher model
- ✅ **Ready for immediate use** with the new tokenizer

**Example expansions:**
```bash
# For Qwen2 teachers (151K vocabulary)
python expand_vocab.py \
  --model_repo_id "shivash/MyAwesome-299M-Model" \
  --new_tokenizer_repo_id "Qwen/Qwen2-1.5B" \
  --output_dir "./expanded-qwen-vocab"

# For Llama 3 teachers (128K vocabulary)
python expand_vocab.py \
  --model_repo_id "shivash/MyAwesome-299M-Model" \
  --new_tokenizer_repo_id "meta-llama/Meta-Llama-3-8B" \
  --output_dir "./expanded-llama3-vocab"
```

After expansion, you can distill knowledge from **any** teacher model with that vocabulary! 🚀

## 🔧 Training Your Own Adapters

### Method 1: Use the Framework Scripts

```bash
# Clone the Transfer-First LLM Framework
git clone https://github.com/your-username/transfer-first-llm.git
cd transfer-first-llm

# Install dependencies
pip install -e ".[dev]"

# Train custom adapters
python scripts/train_task_adapters.py --task reasoning --epochs 3 --test
```

### Method 2: Manual Training

```python
from transformers import TrainingArguments, Trainer
from peft import LoraConfig, get_peft_model
import torch

# Setup model with LoRA
model = AutoModelForCausalLM.from_pretrained("shivash/MyAwesome-299M-Model")
lora_config = LoraConfig(
    task_type="CAUSAL_LM",
    r=8, lora_alpha=16, lora_dropout=0.1,
    target_modules=["q_proj", "v_proj", "o_proj"]
)
model = get_peft_model(model, lora_config)

# Prepare your dataset
# dataset = your_formatted_dataset

# Training arguments
training_args = TrainingArguments(
    output_dir="./my-adapter",
    num_train_epochs=3,
    per_device_train_batch_size=4,
    learning_rate=1e-4,
    logging_steps=10,
)

# Train
trainer = Trainer(
    model=model,
    args=training_args,
    train_dataset=dataset,
    tokenizer=tokenizer
)
trainer.train()

# Save adapter
model.save_pretrained("./my-custom-adapter")
```
