**The Generative AI Pipeline DSL** - Compose, evaluate, and deploy LLM pipelines with confidence.

```synth
pipeline CustomerSupport {
    // Multi-model routing with A/B testing
    router intent_classifier {
        strategy: ab_split(0.5)
        routes: [
            {name: "gpt4", target: gpt4_model},
            {name: "claude", target: claude_model}
        ]
    }
    
    // Built-in safety & compliance
    guardrail safety {
        toxicity_threshold: 0.1
        pii_detection: true
        bias_check: ["gender", "race"]
    }
    
    // Smart caching & evaluation
    cache responses {
        ttl: 3600
        strategy: semantic_similarity(0.95)
    }
}
```

## 🚀 Quick Start

### Install the VS Code Extension (Free)

1. Open VS Code
2. Search for "SynthLang" in Extensions
3. Click Install

### Install the CLI

```bash

```

### Your First Pipeline

Create `hello.synth`:

```synth
pipeline HelloWorld {
    prompt greeting {
        template: """
        Generate a friendly greeting for {{name}}.
        Make it warm and welcoming!
        """
    }
    
    model gpt {
        provider: "openai"
        model: "gpt-3.5-turbo"
        temperature: 0.7
    }
    
    edges: [
        input -> greeting -> gpt -> output
    ]
}

// Run with: synth run hello.synth --input '{"name": "Alice"}'
```

## 📊 Evaluation & Testing

```synth
eval CustomerSupportQuality {
    dataset: "support_test_v1"  // Versioned dataset
    
    metrics: {
        accuracy: true,
        toxicity: true,
        bias: true,
        latency_p95: 2000  // ms
    }
    
    comparison: {
        baseline: "gpt-3.5",
        candidates: ["CustomerSupport"],
        significance: 0.95
    }
}
```

## 🛡️ Safety First

Every pipeline automatically includes:

- **Toxicity Detection**: Perspective API integration
- **Bias Testing**: Multi-dimensional bias detection
- **PII Protection**: Automatic redaction
- **Adversarial Testing**: Jailbreak prevention
- **Audit Logging**: Complete traceability

## 🔧 Advanced Features

### Multi-Stage Pipelines
```synth
pipeline MultiStage {
    // Stage 1: Classification
    model classifier { ... }
    
    // Stage 2: Specialized routing
    router by_intent {
        strategy: conditional
        routes: [
            {condition: "intent == 'technical'", target: tech_expert},
            {condition: "intent == 'billing'", target: billing_expert}
        ]
    }
}
```

        "response_quality",
        "latency",
        "cost"
    ]
    
    auto_optimize: true  // Automatically shift traffic
}
```
