## Usage

### Installation

```bash
pip install transformers torch accelerate
```

### Basic Usage

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

# Load model and tokenizer
model = AutoModelForCausalLM.from_pretrained(
    "Kiy-K/Fyodor-Mini-3B",
    torch_dtype=torch.bfloat16,
    trust_remote_code=True,
    device_map="auto"
)

tokenizer = AutoTokenizer.from_pretrained("Kiy-K/Fyodor-Mini-3B")

# Generate text
prompt = """### Instruction:
Write a Python function to calculate Fibonacci numbers using dynamic programming.

### Response:
"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

with torch.no_grad():
    outputs = model.generate(
        **inputs,
        max_new_tokens=512,
        temperature=0.7,
        top_p=0.95,
        do_sample=True,
        pad_token_id=tokenizer.eos_token_id
    )

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

### Code Generation Example

```python
prompt = """### Instruction:
Create a Python class for a binary search tree with insert and search methods.

### Response:
"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.2)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

### Tool Calling Example

```python
prompt = """You have access to the following functions:

[
  {
    "name": "get_weather",
    "description": "Get current weather for a location",
    "parameters": {
      "location": {"type": "string", "description": "City name"}
    }
  }
]

User: What's the weather in Paris?
Assistant:"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.3)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

### Math Problem Solving

```python
prompt = """Question: A train travels 120 km in 2 hours. What is its average speed in km/h?
Answer:"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.1)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

## Limitations

- Context window limited to 1024 tokens during training (base model supports up to 2048)
- May occasionally generate incorrect information or code
- Not specifically optimized for languages other than English
- Should not be used for medical, legal, or other professional advice without expert review
- Generated code should always be reviewed and tested before production use
- May exhibit biases present in the training data

## Ethical Considerations

- This model can generate code that may have security vulnerabilities - always review before deployment
- The model should not be used to generate malicious code or harmful content
- Be aware of potential biases inherited from training data
- Not suitable for making critical decisions without human oversight
- Users are responsible for ensuring appropriate use of generated content

## Performance Benchmarks

Training metrics:
- **Final Validation Loss**: 0.3240
- **Training Strategy**: Hard LoRA merge
- **Perplexity**: ~1.38 (estimated from loss)
