Advanced Usage

Function Calling Implementation

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Load model and tokenizer
model_id = "mistralai/Mistral-7B-Instruct-v0.3"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id, 
    torch_dtype=torch.bfloat16, 
    device_map="auto"
)

# Define a function for the model to call
def get_current_weather(location: str, format: str):
    """
    Get the current weather for a location
    
    Args:
        location: The city and state, e.g. San Francisco, CA
        format: Temperature unit (celsius/fahrenheit)
    """
    # Implementation would go here
    return f"Weather in {location}: 22°{format[0].upper()}, sunny"

# Set up conversation with tools
conversation = [
    {"role": "user", "content": "What's the weather like in Tokyo?"}
]
tools = [get_current_weather]

# Process with function calling
inputs = tokenizer.apply_chat_template(
    conversation,
    tools=tools,
    add_generation_prompt=True,
    return_dict=True,
    return_tensors="pt"
)

# Generate response
with torch.no_grad():
    outputs = model.generate(
        **inputs.to(model.device),
        max_new_tokens=1000,
        temperature=0.1,
        do_sample=True
    )

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

Production Deployment Considerations

Hardware Requirements

Configuration	GPU Memory	Use Case
Minimum	16GB	Development/Testing
Recommended	24GB+	Production Workloads
Optimal	40GB+	High-throughput Applications

Performance Optimization

• Quantization: Use 4-bit or 8-bit quantization for memory efficiency
• Batch Processing: Implement batching for multiple concurrent requests
• Caching: Cache model weights and frequent responses
• Load Balancing: Distribute requests across multiple GPU instances

Safety and Limitations

Important Considerations

No Built-in Moderation: Implement external content filtering Hallucination Risk: Verify factual claims in critical applications Bias Potential: Monitor outputs for demographic and cultural biases Resource Requirements: Ensure adequate computational resources

Recommended Safety Measures

1. Content Filtering: Implement pre and post-processing filters
2. Human Oversight: Include human review for sensitive applications
3. Bias Testing: Regular evaluation across diverse user groups
4. Error Handling: Robust error handling and fallback mechanisms
5. Usage Monitoring: Track and analyze model behavior patterns

Performance Benchmarks

Benchmark	Score	Comparison
MMLU	Competitive	Strong across knowledge domains
HumanEval	High	Excellent code generation
HellaSwag	Excellent	Superior common sense reasoning
GSM8K	Good	Solid mathematical capabilities

Troubleshooting

Common Issues and Solutions

Memory Errors

# Use gradient checkpointing and smaller batch sizes
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    low_cpu_mem_usage=True
)

Slow Inference

# Enable optimizations
from transformers import BitsAndBytesConfig

quantization_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_compute_dtype=torch.bfloat16
)

model = AutoModelForCausalLM.from_pretrained(
    model_id,
    quantization_config=quantization_config
)
