**TorchForge** is an enterprise-grade PyTorch framework that bridges the gap between research and production. Built with governance-first principles, it provides seamless integration with enterprise workflows, compliance frameworks (NIST AI RMF), and production deployment pipelines.

## 🎯 Why TorchForge?

Modern enterprises face critical challenges deploying PyTorch models to production:

- **Governance Gap**: No built-in compliance tracking for AI regulations (NIST AI RMF, EU AI Act)
- **Production Readiness**: Research code lacks monitoring, versioning, and audit trails
- **Performance Overhead**: Manual profiling and optimization for each deployment
- **Integration Complexity**: Difficult to integrate with existing MLOps ecosystems
- **Safety & Reliability**: Limited bias detection, drift monitoring, and error handling

TorchForge solves these challenges with a production-first wrapper around PyTorch.

```

## 🚀 Quick Start

### Basic Usage

```python
import torch
import torch.nn as nn
from torchforge import ForgeModel, ForgeConfig

# Create a standard PyTorch model
class SimpleNet(nn.Module):
    def __init__(self):
        super().__init__()
        self.fc = nn.Linear(10, 2)
    
    def forward(self, x):
        return self.fc(x)

# Wrap with TorchForge
config = ForgeConfig(
    model_name="simple_classifier",
    version="1.0.0",
    enable_monitoring=True,
    enable_governance=True
)

model = ForgeModel(SimpleNet(), config=config)

# Train with automatic tracking
x = torch.randn(32, 10)
y = torch.randint(0, 2, (32,))

output = model(x)
model.track_prediction(output, y)  # Automatic bias and fairness tracking
```

### Enterprise Deployment

```python
from torchforge.deployment import DeploymentManager

# Deploy to cloud with monitoring
deployment = DeploymentManager(
    model=model,
    cloud_provider="aws",
    instance_type="ml.g4dn.xlarge"
)

deployment.deploy(
    enable_autoscaling=True,
    min_instances=2,
    max_instances=10,
    health_check_path="/health"
)

# Monitor in real-time
metrics = deployment.get_metrics(window="1h")
print(f"Avg Latency: {metrics.latency_p95}ms")
print(f"Throughput: {metrics.requests_per_second} req/s")
```

### Governance & Compliance

```python
from torchforge.governance import ComplianceChecker, NISTFramework

# Check NIST AI RMF compliance
checker = ComplianceChecker(framework=NISTFramework.RMF_1_0)
report = checker.assess_model(model)

print(f"Compliance Score: {report.overall_score}/100")
print(f"Risk Level: {report.risk_level}")
print(f"Recommendations: {report.recommendations}")

# Export audit report
report.export_pdf("compliance_report.pdf")
```

## 📚 Comprehensive Examples
