+
+## 🎮 Core Features
+
+### 💬 Universal Chat Interface
+
+Works identically across all providers:

 ```typescript
-const textEncoder = new TextEncoder();
-const textDecoder = new TextDecoder();
+// Use GPT-4 for complex reasoning
+const gptResponse = await ai.openaiProvider.chat({
+  systemMessage: 'You are a expert physicist.',
+  userMessage: 'Explain the implications of quantum entanglement',
+  messageHistory: []
+});

-// Create input and output streams
-const { writable, readable } = new TransformStream();
-const writer = writable.getWriter();
+// Use Claude for safety-critical applications
+const claudeResponse = await ai.anthropicProvider.chat({
+  systemMessage: 'You are a medical advisor.',
+  userMessage: 'Review this patient data for concerns',
+  messageHistory: []
+});

-// Send a message
-const message = {
-  role: 'user',
-  content: 'Tell me a story about a brave knight'
-};
+// Use Groq for lightning-fast responses
+const groqResponse = await ai.groqProvider.chat({
+  systemMessage: 'You are a code reviewer.',
+  userMessage: 'Quick! Find the bug in this code: ...',
+  messageHistory: []
+});
+```

-writer.write(textEncoder.encode(JSON.stringify(message) + '\n'));
+### 🌊 Real-Time Streaming

-// Process the response stream
-const stream = await smartAi.openaiProvider.chatStream(readable);
+Build responsive chat interfaces with token-by-token streaming:
+
+```typescript
+// Create a chat stream
+const stream = await ai.openaiProvider.chatStream(inputStream);
 const reader = stream.getReader();

+// Display responses as they arrive
 while (true) {
  const { done, value } = await reader.read();
  if (done) break;
-  console.log('AI:', value); // Process each chunk of the response
+  
+  // Update UI in real-time
+  process.stdout.write(value);
 }
 ```

-### Audio Generation
+### 🎙️ Text-to-Speech

-For providers that support audio generation (currently OpenAI):
+Generate natural voices with OpenAI:

 ```typescript
-const audioStream = await smartAi.openaiProvider.audio({
-  message: 'Hello, this is a test of text-to-speech'
+const audioStream = await ai.openaiProvider.audio({
+  message: 'Welcome to the future of AI development!'
 });

-// Handle the audio stream (e.g., save to file or play)
+// Stream directly to speakers
+audioStream.pipe(speakerOutput);
+
+// Or save to file
+audioStream.pipe(fs.createWriteStream('welcome.mp3'));
 ```

-### Document Processing
+### 👁️ Vision Analysis

-For providers that support document processing (OpenAI, Ollama, and Anthropic):
+Understand images with multiple providers:

 ```typescript
-// Using OpenAI
-const result = await smartAi.openaiProvider.document({
-  systemMessage: 'Classify the document type',
-  userMessage: 'What type of document is this?',
-  messageHistory: [],
-  pdfDocuments: [pdfBuffer] // Uint8Array of PDF content
+const image = fs.readFileSync('product-photo.jpg');
+
+// OpenAI: General purpose vision
+const gptVision = await ai.openaiProvider.vision({
+  image,
+  prompt: 'Describe this product and suggest marketing angles'
 });

-// Using Ollama with llava
-const analysis = await smartAi.ollamaProvider.document({
-  systemMessage: 'You are a document analysis assistant',
-  userMessage: 'Extract the key information from this document',
-  messageHistory: [],
-  pdfDocuments: [pdfBuffer] // Uint8Array of PDF content
+// Anthropic: Detailed analysis
+const claudeVision = await ai.anthropicProvider.vision({
+  image,
+  prompt: 'Identify any safety concerns or defects'
 });

-// Using Anthropic with Claude 3
-const anthropicAnalysis = await smartAi.anthropicProvider.document({
-  systemMessage: 'You are a document analysis assistant',
-  userMessage: 'Please analyze this document and extract key information',
-  messageHistory: [],
-  pdfDocuments: [pdfBuffer] // Uint8Array of PDF content
+// Ollama: Private, local analysis
+const ollamaVision = await ai.ollamaProvider.vision({
+  image,
+  prompt: 'Extract all text and categorize the content'
 });
 ```

-Both providers will:
-1. Convert PDF documents to images
-2. Process each page using their vision models
-3. Return a comprehensive analysis based on the system message and user query
+### 📄 Document Intelligence

-### Vision Processing
-
-For providers that support vision tasks (OpenAI, Ollama, and Anthropic):
+Extract insights from PDFs with AI:

 ```typescript
-// Using OpenAI's GPT-4 Vision
-const description = await smartAi.openaiProvider.vision({
-  image: imageBuffer, // Buffer containing the image data
-  prompt: 'What do you see in this image?'
+const contract = fs.readFileSync('contract.pdf');
+const invoice = fs.readFileSync('invoice.pdf');
+
+// Analyze documents
+const analysis = await ai.openaiProvider.document({
+  systemMessage: 'You are a legal expert.',
+  userMessage: 'Compare these documents and highlight key differences',
+  messageHistory: [],
+  pdfDocuments: [contract, invoice]
 });

-// Using Ollama's Llava model
-const analysis = await smartAi.ollamaProvider.vision({
-  image: imageBuffer,
-  prompt: 'Analyze this image in detail'
-});
-
-// Using Anthropic's Claude 3
-const anthropicAnalysis = await smartAi.anthropicProvider.vision({
-  image: imageBuffer,
-  prompt: 'Please analyze this image and describe what you see'
+// Multi-document analysis
+const taxDocs = [form1099, w2, receipts];
+const taxAnalysis = await ai.anthropicProvider.document({
+  systemMessage: 'You are a tax advisor.',
+  userMessage: 'Prepare a tax summary from these documents',
+  messageHistory: [],
+  pdfDocuments: taxDocs
 });
 ```

-## Error Handling
+### 🔄 Persistent Conversations

-All providers implement proper error handling. It's recommended to wrap API calls in try-catch blocks:
+Maintain context across interactions:

 ```typescript
-try {
-  const response = await smartAi.openaiProvider.chat({
-    systemMessage: 'You are a helpful assistant.',
-    userMessage: 'Hello!',
+// Create a coding assistant conversation
+const assistant = ai.createConversation('openai');
+await assistant.setSystemMessage('You are an expert TypeScript developer.');
+
+// First question
+const inputWriter = assistant.getInputStreamWriter();
+await inputWriter.write('How do I implement a singleton pattern?');
+
+// Continue the conversation
+await inputWriter.write('Now show me how to make it thread-safe');
+
+// The assistant remembers the entire context
+```
+
+## 🚀 Real-World Examples
+
+### Build a Customer Support Bot
+
+```typescript
+const supportBot = new SmartAi({
+  anthropicToken: process.env.ANTHROPIC_KEY // Claude for empathetic responses
+});
+
+async function handleCustomerQuery(query: string, history: ChatMessage[]) {
+  try {
+    const response = await supportBot.anthropicProvider.chat({
+      systemMessage: `You are a helpful customer support agent. 
+                      Be empathetic, professional, and solution-oriented.`,
+      userMessage: query,
+      messageHistory: history
+    });
+    
+    return response.message;
+  } catch (error) {
+    // Fallback to another provider if needed
+    return await supportBot.openaiProvider.chat({...});
+  }
+}
+```
+
+### Create a Code Review Assistant
+
+```typescript
+const codeReviewer = new SmartAi({
+  groqToken: process.env.GROQ_KEY // Groq for speed
+});
+
+async function reviewCode(code: string, language: string) {
+  const startTime = Date.now();
+  
+  const review = await codeReviewer.groqProvider.chat({
+    systemMessage: `You are a ${language} expert. Review code for:
+                    - Security vulnerabilities
+                    - Performance issues  
+                    - Best practices
+                    - Potential bugs`,
+    userMessage: `Review this code:\n\n${code}`,
    messageHistory: []
  });
-} catch (error) {
-  console.error('AI provider error:', error.message);
+  
+  console.log(`Review completed in ${Date.now() - startTime}ms`);
+  return review.message;
 }
 ```

+### Build a Research Assistant
+
+```typescript
+const researcher = new SmartAi({
+  perplexityToken: process.env.PERPLEXITY_KEY
+});
+
+async function research(topic: string) {
+  // Perplexity excels at web-aware research
+  const findings = await researcher.perplexityProvider.chat({
+    systemMessage: 'You are a research assistant. Provide factual, cited information.',
+    userMessage: `Research the latest developments in ${topic}`,
+    messageHistory: []
+  });
+  
+  return findings.message;
+}
+```
+
+### Local AI for Sensitive Data
+
+```typescript
+const localAI = new SmartAi({
+  ollama: {
+    baseUrl: 'http://localhost:11434',
+    model: 'llama2',
+    visionModel: 'llava'
+  }
+});
+
+// Process sensitive documents without leaving your infrastructure
+async function analyzeSensitiveDoc(pdfBuffer: Buffer) {
+  const analysis = await localAI.ollamaProvider.document({
+    systemMessage: 'Extract and summarize key information.',
+    userMessage: 'Analyze this confidential document',
+    messageHistory: [],
+    pdfDocuments: [pdfBuffer]
+  });
+  
+  // Data never leaves your servers
+  return analysis.message;
+}
+```
+
+## ⚡ Performance Tips
+
+### 1. Provider Selection Strategy
+
+```typescript
+class SmartAIRouter {
+  constructor(private ai: SmartAi) {}
+  
+  async query(message: string, requirements: {
+    speed?: boolean;
+    accuracy?: boolean;
+    cost?: boolean;
+    privacy?: boolean;
+  }) {
+    if (requirements.privacy) {
+      return this.ai.ollamaProvider.chat({...}); // Local only
+    }
+    if (requirements.speed) {
+      return this.ai.groqProvider.chat({...}); // 10x faster
+    }
+    if (requirements.accuracy) {
+      return this.ai.anthropicProvider.chat({...}); // Best reasoning
+    }
+    // Default fallback
+    return this.ai.openaiProvider.chat({...});
+  }
+}
+```
+
+### 2. Streaming for Large Responses
+
+```typescript
+// Don't wait for the entire response
+async function streamResponse(userQuery: string) {
+  const stream = await ai.openaiProvider.chatStream(createInputStream(userQuery));
+  
+  // Process tokens as they arrive
+  for await (const chunk of stream) {
+    updateUI(chunk); // Immediate feedback
+    await processChunk(chunk); // Parallel processing
+  }
+}
+```
+
+### 3. Parallel Multi-Provider Queries
+
+```typescript
+// Get the best answer from multiple AIs
+async function consensusQuery(question: string) {
+  const providers = [
+    ai.openaiProvider.chat({...}),
+    ai.anthropicProvider.chat({...}),
+    ai.perplexityProvider.chat({...})
+  ];
+  
+  const responses = await Promise.all(providers);
+  return synthesizeResponses(responses);
+}
+```
+
+## 🛠️ Advanced Features
+
+### Custom Streaming Transformations
+
+```typescript
+// Add real-time translation
+const translationStream = new TransformStream({
+  async transform(chunk, controller) {
+    const translated = await translateChunk(chunk);
+    controller.enqueue(translated);
+  }
+});
+
+const responseStream = await ai.openaiProvider.chatStream(input);
+const translatedStream = responseStream.pipeThrough(translationStream);
+```
+
+### Error Handling & Fallbacks
+
+```typescript
+class ResilientAI {
+  private providers = ['openai', 'anthropic', 'groq'];
+  
+  async query(opts: ChatOptions): Promise<ChatResponse> {
+    for (const provider of this.providers) {
+      try {
+        return await this.ai[`${provider}Provider`].chat(opts);
+      } catch (error) {
+        console.warn(`${provider} failed, trying next...`);
+        continue;
+      }
+    }
+    throw new Error('All providers failed');
+  }
+}
+```
+
+### Token Counting & Cost Management
+
+```typescript
+// Track usage across providers
+class UsageTracker {
+  async trackedChat(provider: string, options: ChatOptions) {
+    const start = Date.now();
+    const response = await ai[`${provider}Provider`].chat(options);
+    
+    const usage = {
+      provider,
+      duration: Date.now() - start,
+      inputTokens: estimateTokens(options),
+      outputTokens: estimateTokens(response.message)
+    };
+    
+    await this.logUsage(usage);
+    return response;
+  }
+}
+```

+# SmartAI Research API Implementation
+
+This document describes the new research capabilities added to the SmartAI library, enabling web search and deep research features for OpenAI and Anthropic providers.
+
+## Features Added
+
+### 1. Research Method Interface
+
+Added a new `research()` method to the `MultiModalModel` abstract class with the following interfaces:
+
+```typescript
+interface ResearchOptions {
+  query: string;
+  searchDepth?: 'basic' | 'advanced' | 'deep';
+  maxSources?: number;
+  includeWebSearch?: boolean;
+  background?: boolean;
+}
+
+interface ResearchResponse {
+  answer: string;
+  sources: Array<{
+    url: string;
+    title: string;
+    snippet: string;
+  }>;
+  searchQueries?: string[];
+  metadata?: any;
+}
+```
+
+### 2. OpenAI Provider Research Implementation
+
+The OpenAI provider now supports:
+- **Deep Research API** with models:
+  - `o3-deep-research-2025-06-26` (comprehensive analysis)
+  - `o4-mini-deep-research-2025-06-26` (lightweight, faster)
+- **Web Search** for standard models (gpt-5, o3, o3-pro, o4-mini)
+- **Background processing** for async deep research tasks
+
+### 3. Anthropic Provider Research Implementation
+
+The Anthropic provider now supports:
+- **Web Search API** with Claude models
+- **Domain filtering** (allow/block lists)
+- **Progressive searches** for comprehensive research
+- **Citation extraction** from responses
+
+### 4. Perplexity Provider Research Implementation
+
+The Perplexity provider implements research using:
+- **Sonar models** for standard searches
+- **Sonar Pro** for deep research
+- Built-in citation support
+
+### 5. Other Providers
+
+Added research method stubs to:
+- Groq Provider
+- Ollama Provider
+- xAI Provider
+- Exo Provider
+
+These providers throw a "not yet supported" error when research is called, maintaining interface compatibility.
+
+## Usage Examples
+
+### Basic Research with OpenAI
+
+```typescript
+import { OpenAiProvider } from '@push.rocks/smartai';
+
+const openai = new OpenAiProvider({
+  openaiToken: 'your-api-key',
+  researchModel: 'o4-mini-deep-research-2025-06-26'
+});
+
+await openai.start();
+
+const result = await openai.research({
+  query: 'What are the latest developments in quantum computing?',
+  searchDepth: 'basic',
+  includeWebSearch: true
+});
+
+console.log(result.answer);
+console.log('Sources:', result.sources);
+```
+
+### Deep Research with OpenAI
+
+```typescript
+const deepResult = await openai.research({
+  query: 'Comprehensive analysis of climate change mitigation strategies',
+  searchDepth: 'deep',
+  background: true
+});
+```
+
+### Research with Anthropic
+
+```typescript
+import { AnthropicProvider } from '@push.rocks/smartai';
+
+const anthropic = new AnthropicProvider({
+  anthropicToken: 'your-api-key',
+  enableWebSearch: true,
+  searchDomainAllowList: ['nature.com', 'science.org']
+});
+
+await anthropic.start();
+
+const result = await anthropic.research({
+  query: 'Latest breakthroughs in CRISPR gene editing',
+  searchDepth: 'advanced'
+});
+```
+
+### Research with Perplexity
+
+```typescript
+import { PerplexityProvider } from '@push.rocks/smartai';
+
+const perplexity = new PerplexityProvider({
+  perplexityToken: 'your-api-key'
+});
+
+const result = await perplexity.research({
+  query: 'Current state of autonomous vehicle technology',
+  searchDepth: 'deep' // Uses Sonar Pro model
+});
+```
+
+## Configuration Options
+
+### OpenAI Provider
+- `researchModel`: Specify deep research model (default: `o4-mini-deep-research-2025-06-26`)
+- `enableWebSearch`: Enable web search for standard models
+
+### Anthropic Provider
+- `enableWebSearch`: Enable web search capabilities
+- `searchDomainAllowList`: Array of allowed domains
+- `searchDomainBlockList`: Array of blocked domains
+
+## API Pricing
+
+- **OpenAI Deep Research**: $10 per 1,000 calls
+- **Anthropic Web Search**: $10 per 1,000 searches + standard token costs
+- **Perplexity Sonar**: $5 per 1,000 searches (Sonar Pro)
+
+## Testing
+
+Run the test suite:
+
+```bash
+pnpm test test/test.research.ts
+```
+
+All providers have been tested to ensure:
+- Research methods are properly exposed
+- Interfaces are correctly typed
+- Unsupported providers throw appropriate errors
+
+## Next Steps
+
+Future enhancements could include:
+1. Implementing Google Gemini Grounding API support
+2. Adding Brave Search API integration
+3. Implementing retry logic for rate limits
+4. Adding caching for repeated queries
+5. Supporting batch research operations
+
+## Notes
+
+- The implementation maintains backward compatibility
+- All existing methods continue to work unchanged
+- Research capabilities are optional and don't affect existing functionality
