 # Changelog
 
+## 2025-02-03 - 0.2.0 - feat(provider.anthropic)
+Add support for vision and document processing in Anthropic provider
+
+- Implemented vision tasks for Anthropic provider using Claude-3-opus-20240229 model.
+- Implemented document processing for Anthropic provider, supporting conversion of PDF documents to images and analysis with Claude-3-opus-20240229 model.
+- Updated documentation to reflect the new capabilities of the Anthropic provider.
+
+## 2025-02-03 - 0.1.0 - feat(providers)
+Add vision and document processing capabilities to providers
+
+- OpenAI and Ollama providers now support vision tasks using GPT-4 Vision and Llava models respectively.
+- Document processing has been implemented for OpenAI and Ollama providers, converting PDFs to images for analysis.
+- Introduced abstract methods for vision and document processing in the MultiModalModel class.
+- Updated the readme file with examples for vision and document processing.

+For providers that support document processing (OpenAI, Ollama, and Anthropic):
 
 ```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

+
+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

+For providers that support vision tasks (OpenAI, Ollama, and Anthropic):

+```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?'
+});
+
+// Using Ollama's Llava model
+const analysis = await smartAi.ollamaProvider.vision({
+  image: imageBuffer,
+  prompt: 'Analyze this image in detail'
+});
+
+// Using Anthropic's Claude 3
