+## 🎯 Key Components
+
+### Language Model Implementations
+
+```typescript
+class OpenAILM {
+  async generate(prompt: string, options?): Promise<string>
+  getTokenUsage(): { input: number; output: number }
+  resetTokenUsage(): void
+}
+
+class AnthropicLM {
+  async generate(prompt: string, options?): Promise<string>
+  getTokenUsage(): { input: number; output: number }
+  resetTokenUsage(): void
+}
+```
+
+### DSPy Modules
+
+```typescript
+class SyntheticDataModule extends ChainOfThought {
+  // Generates synthetic data with reasoning
+  // Auto-includes reasoning in output
+}
+
+class DataQualityModule extends PredictModule {
+  // Validates data quality
+  // Returns validation results
+}
+```
+
+### Benchmark Suite
+
+```typescript
+class DSPyMultiModelBenchmark {
+  addModel(config: ModelConfig): void
+  async runComparison(sampleSize: number): Promise<ComparisonReport>
+  async generateReport(comparison: ComparisonReport): Promise<string>
+}
+```
+
+## 🚀 Usage
+
+### Quick Start
+
+```bash
+# 1. Set API keys
+export OPENAI_API_KEY="sk-..."
+export ANTHROPIC_API_KEY="sk-ant-..."
+
+# 2. Run benchmark (easiest)
+./training/run-multi-model-benchmark.sh
+
+# 3. Or run directly
+npx tsx training/dspy-multi-model-benchmark.ts
+
+# 4. With custom sample size
+SAMPLE_SIZE=1000 npx tsx training/dspy-multi-model-benchmark.ts
+```
+
+### Programmatic Usage
+
+```typescript
+import { DSPyMultiModelBenchmark } from './training/dspy-multi-model-benchmark';
+
+const benchmark = new DSPyMultiModelBenchmark();
+
+// Add models
+benchmark.addModel({
+  name: 'GPT-4',
+  provider: 'openai',
+  modelId: 'gpt-4',
+  apiKey: process.env.OPENAI_API_KEY,
+  costPer1kTokens: { input: 0.03, output: 0.06 },
+  maxTokens: 8192
+});
+
+// Run comparison
+const results = await benchmark.runComparison(1000);
+
+// Generate reports
+await benchmark.generateReport(results);
+```
+
+## 📊 Benchmark Workflow
+
+```

+  │
+  ├─ 3. MIPROv2 Optimization
+  │    ├─ Bayesian prompt optimization
+  │    ├─ Run 3 optimization trials
+  │    ├─ Use Expected Improvement acquisition
+  │    └─ Measure quality gain
+  │
+  ├─ 4. Performance Testing
+  │    ├─ Measure latency (P50, P95, P99)
+  │    ├─ Calculate throughput
+  │    └─ Track success rate
+  │
+  └─ 5. Cost Analysis

+## 🛠️ Troubleshooting
+
+### Common Issues
+
+**1. API Key Errors**
+```bash
+# Check keys are set
+echo $OPENAI_API_KEY
+echo $ANTHROPIC_API_KEY
+
+# Set temporarily
+export OPENAI_API_KEY="sk-..."
+export ANTHROPIC_API_KEY="sk-ant-..."
+```
+
+**2. Import Errors**
+```bash
+# Verify dspy.ts is installed
+npm list dspy.ts
+
+# Reinstall if needed
+npm install dspy.ts@2.1.1
+```
+
+**3. Memory Issues**
+```bash
+# Reduce sample size
+SAMPLE_SIZE=10 npx tsx training/dspy-multi-model-benchmark.ts
+```
+
+**4. Rate Limiting**
+- Add delays between requests (modify code)
+- Use smaller sample sizes
+- Run models separately
+
+## 📚 Technical Details
+
+### Dependencies
+- `dspy.ts@2.1.1` - Main framework
+- Node.js >= 18.0.0
+- TypeScript support
+- Native `fetch` API
+
+### Import Path
+Due to dspy.ts package structure:
+```typescript
+const dspy = require('dspy.ts/dist/src/index');
+```
+
+### Module Inheritance
+```
+Module (base)
+  ├─ PredictModule (single-step prediction)
+  ├─ ChainOfThought (reasoning-based)
+  ├─ ReAct (action-based)
+  └─ Custom modules...
+```
+
+### Optimizer Chain
+```
+BaseModule → BootstrapFewShot → Optimized Module v1
+           → MIPROv2          → Optimized Module v2
+```
+
+## 🎯 Next Steps
+
+1. **Run Test Benchmark**:
+   ```bash
+   SAMPLE_SIZE=10 ./training/run-multi-model-benchmark.sh
+   ```
+
+2. **Analyze Results**:
+   - Review markdown report
+   - Examine JSON data
+   - Compare optimization improvements
+
+3. **Scale Up**:
+   ```bash
+   SAMPLE_SIZE=1000 ./training/run-multi-model-benchmark.sh
+   ```
+
+4. **Customize**:
+   - Add custom models
+   - Modify schema
+   - Adjust optimizer parameters
+   - Implement custom metrics
+
+5. **Integrate**:
+   - Use as library in your projects
+   - Extend with custom modules
+   - Build on top of framework
