 ```
 
-### Creating Conversations with AI
+## Usage Examples
 
-`SmartAi` provides a flexible interface to create and manage conversations with different AI providers. You can create a conversation with any supported AI provider like OpenAI or Anthropic by specifying the provider you want to use:
+### Chat Interactions
+
+**Synchronous Chat:**
 
 ```typescript
-const openAiConversation = await smartAi.createConversation('openai');
+const response = await smartAi.openaiProvider.chat({
-const anthropicConversation = await smartAi.createConversation('anthropic');
+  systemMessage: 'You are a helpful assistant.',
-```
+  userMessage: 'What is the capital of France?',
-
+  messageHistory: [] // Include previous conversation messages if applicable
-### Chatting with AI
-
-Once you have a conversation instance, you can start sending messages to the AI and receive responses. Each conversation object provides methods to interact in a synchronous or asynchronous manner, depending on your use case.
-
-#### Synchronous Chat Example
-
-Here's how you can have a synchronous chat with OpenAI:
-
-```typescript
-const response = await openAiConversation.chat({
-  systemMessage: 'This is a greeting from the system.',
-  userMessage: 'Hello, AI! How are you today?',
-  messageHistory: [] // Previous messages in the conversation
 });
 
-console.log(response.message); // Log the response from AI
+console.log(response.message);
 ```
 
-#### Streaming Chat Example
+### Streaming Chat
 
-For real-time, streaming interactions, you can utilize the streaming capabilities provided by the conversation object. This enables a continuous exchange of messages between your application and the AI:
+**Real-Time Streaming:**
 
 ```typescript
-const inputStreamWriter = openAiConversation.getInputStreamWriter();
+const textEncoder = new TextEncoder();
-const outputStream = openAiConversation.getOutputStream();
+const textDecoder = new TextDecoder();
 
-inputStreamWriter.write('Hello, AI! Can you stream responses?');
+// Create a transform stream for sending and receiving data
+const { writable, readable } = new TransformStream();
+const writer = writable.getWriter();
 
-const reader = outputStream.getReader();
+const message = {
-reader.read().then(function processText({done, value}) {
+  role: 'user',
-  if (done) {
+  content: 'Tell me a story about a brave knight'
-    console.log('Stream finished.');
+};
-    return;
+
-  }
+writer.write(textEncoder.encode(JSON.stringify(message) + '\n'));
-  console.log('AI says:', value);
+
-  reader.read().then(processText); // Continue reading messages
+// Start streaming the response
+const stream = await smartAi.openaiProvider.chatStream(readable);
+const reader = stream.getReader();
+
+while (true) {
+  const { done, value } = await reader.read();
+  if (done) break;
+  console.log('AI:', value);
+}
+```
+
+### Audio Generation
+
+Generate audio (supported by providers like OpenAI):
+
+```typescript
+const audioStream = await smartAi.openaiProvider.audio({
+  message: 'Hello, this is a test of text-to-speech'
+});
+
+// Process the audio stream, for example, play it or save to a file.
+```
+
+### Document Processing
+
+Analyze and extract key information from documents:
+
+```typescript
+// Example using OpenAI
+const documentResult = await smartAi.openaiProvider.document({
+  systemMessage: 'Classify the document type',
+  userMessage: 'What type of document is this?',
+  messageHistory: [],
+  pdfDocuments: [pdfBuffer] // Uint8Array containing the PDF content
 });
 ```
 
-### Extending Conversations
+Other providers (e.g., Ollama and Anthropic) follow a similar pattern:
 
-The modular design of `@push.rocks/smartai` allows you to extend conversations with additional features, such as handling audio responses or integrating other AI-powered functionalities. Utilize the provided AI providers' APIs to explore and implement a wide range of AI interactions within your conversations.
+```typescript
+// Using Ollama for document processing
+const ollamaResult = await smartAi.ollamaProvider.document({
+  systemMessage: 'You are a document analysis assistant',
+  userMessage: 'Extract key information from this document',
+  messageHistory: [],
+  pdfDocuments: [pdfBuffer]
+});
+```
 
-### Conclusion
+```typescript
+// Using Anthropic for document processing
+const anthropicResult = await smartAi.anthropicProvider.document({
+  systemMessage: 'Analyze the document',
+  userMessage: 'Please extract the main points',
+  messageHistory: [],
+  pdfDocuments: [pdfBuffer]
+});
+```
 
-With `@push.rocks/smartai`, integrating AI functionalities into your applications becomes streamlined and efficient. By leveraging the standardized interface provided by the package, you can easily converse with multiple AI models, expanding the capabilities of your applications with cutting-edge AI features. Whether you're implementing simple chat interactions or complex, real-time communication flows, `@push.rocks/smartai` offers the tools and flexibility needed to create engaging, AI-enhanced experiences.

+
+// Using Anthropic for vision analysis
+const anthropicImageAnalysis = await smartAi.anthropicProvider.vision({
+  image: imageBuffer,
+  prompt: 'Describe the contents of this image'
+});
+```
+
+## Error Handling
+
+Always wrap API calls in try-catch blocks to manage errors effectively:
+
+```typescript
+try {
+  const response = await smartAi.openaiProvider.chat({
+    systemMessage: 'You are a helpful assistant.',
+    userMessage: 'Hello!',
+    messageHistory: []
+  });
+  console.log(response.message);
+} catch (error: any) {
+  console.error('AI provider error:', error.message);
+}
+```
+
+## Development
+
+### Running Tests
+
+To run the test suite, use the following command:
+
+```bash
+npm run test
+```
+
+Ensure your environment is configured with the appropriate tokens and settings for the providers you are testing.
