+# Azure AI Inference Provider Implementation Plan
+
+## Overview
+This document outlines the implementation plan for adding Azure AI Inference support as a new provider in `src/api/providers/`. While Azure AI uses OpenAI's API format as a base, there are significant differences in implementation that need to be accounted for.
+
+## Key Differences from OpenAI
+
+### Endpoint Structure
+- OpenAI: `https://api.openai.com/v1/chat/completions`
+- Azure: `https://{resource-name}.openai.azure.com/openai/deployments/{deployment-name}/chat/completions?api-version={api-version}`
+
+### Authentication
+- OpenAI: Uses `Authorization: Bearer sk-...`
+- Azure: Uses `api-key: {key}`
+
+### Request Format
+- OpenAI: Requires `model` field in request body
+- Azure: Omits `model` from body (uses deployment name in URL instead)
+
+### Special Considerations
+- Required API version in URL query parameter
+- Model-Mesh deployments require additional header: `x-ms-model-mesh-model-name`
+- Different API versions for different features (e.g., 2023-12-01-preview, 2024-02-15-preview)
+
+## Dependencies
+
+```typescript
+import { Anthropic } from "@anthropic-ai/sdk"
+import OpenAI, { AzureOpenAI } from "openai"

+        )
+      }
+      throw error
+    }
+  }
+}
+```
+
+## Required Updates to ApiHandlerOptions
+
+Add to ApiHandlerOptions interface in shared/api.ts:
+
+```typescript
+azureAiEndpoint?: string
+azureAiKey?: string
+azureAiDeployments?: {
+  [key in AzureAiModelId]?: {
+    name: string
+    apiVersion: string
+    modelMeshName?: string
+  }
+}
+```
+
+## Testing Plan
+
+1. Create __tests__ directory with azure-ai.test.ts:
+   ```typescript
+   describe('AzureAiHandler', () => {
+     // Test URL construction
+     test('constructs correct Azure endpoint URL', () => {})
+     
+     // Test authentication
+     test('sets correct authentication headers', () => {})
+     
+     // Test deployment configuration
+     test('uses correct deployment names', () => {})
+     test('handles Model-Mesh configuration', () => {})
+     
+     // Test error handling
+     test('handles Azure-specific error format', () => {})
+     
+     // Test request/response format
+     test('omits model from request body', () => {})
+     test('handles Azure response format', () => {})
+   })
+   ```
+
+## Integration Steps
+
+1. Add Azure AI models and types to shared/api.ts
+2. Create azure-ai.ts provider implementation
+3. Add provider tests
+4. Update API handler options
+5. Add deployment configuration support
+6. Implement Azure-specific error handling
+7. Test with real Azure AI endpoints
+
+## Error Handling
+
+Azure returns errors in a specific format:
+```typescript
+interface AzureError {
+  code: string        // e.g., "InternalServerError", "InvalidRequest"
+  message: string
+  target?: string
+  details?: Array<{
+    code: string
+    message: string
+  }>
+}
+```
+
+Implementation should:
+- Parse Azure error format
+- Include error codes in messages
+- Handle deployment-specific errors
+- Provide clear upgrade paths for API version issues
+
+## Documentation Updates
+
+1. Add Azure AI configuration section to README.md:
+   - Endpoint configuration
+   - Authentication setup
+   - Deployment mapping
+   - API version selection
+   - Model-Mesh support
+
+2. Document configuration examples:
+   ```typescript
+   {
+     azureAiEndpoint: "https://your-resource.openai.azure.com",
+     azureAiKey: "your-api-key",
+     azureAiDeployments: {
+       "gpt-4": {
+         name: "your-gpt4-deployment",
+         apiVersion: "2024-02-15-preview",
+         modelMeshName: "optional-model-mesh-name"
+       }
+     }
+   }
+   ```
+
+## Future Improvements
+
+1. Support for Azure-specific features:
+   - Fine-tuning endpoints
+   - Custom deployment configurations
+   - Managed identity authentication
+
+2. Performance optimizations:
+   - Connection pooling
+   - Regional endpoint selection
+   - Automatic API version negotiation
+
+3. Advanced features:
+   - Response format control
+   - Function calling support
+   - Vision model support
