# 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.
## 2025-02-03 - 0.0.19 - fix(core)

### Document Processing
For providers that support document processing (currently OpenAI):
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
});
// 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
});
// 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
});
```
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
### Vision Processing
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
const anthropicAnalysis = await smartAi.anthropicProvider.vision({
image: imageBuffer,
prompt: 'Please analyze this image and describe what you see'
});
```
