# OpenAI Integration with Pixeltable: Complete AI Pipeline Guide

Integrate OpenAI models with Pixeltable for multimodal AI. GPT-4 Vision, DALL-E, and Whisper pipelines with auto-scaling and caching.

## The Problem

Production OpenAI requires managing APIs, caching, error handling, rate limits, and retry logic, which means building custom wrappers and orchestration code.

## The Solution

Pixeltable provides native OpenAI integration with automatic API management, caching, error handling, and multimodal processing. Define AI workflows declaratively.

## Implementation

### Setup OpenAI Integration

Configure OpenAI API and create AI-powered tables

```python
import pixeltable as pxt
from pixeltable.functions import openai
import os

# Set up OpenAI API key (recommended: use environment variable)
os.environ['OPENAI_API_KEY'] = 'your-api-key-here'

# Create table for multimodal content
content = pxt.create_table('ai_content', {
    'text': pxt.String,
    'image': pxt.Image,
    'title': pxt.String
})

# Insert sample data
content.insert([
    {
        'text': 'Analyze this product image for marketing insights',
        'image': '/path/to/product.jpg',
        'title': 'Product Analysis'
    }
])
```

Basic setup for multimodal AI processing with OpenAI.


### GPT-4 Vision Analysis

Image analysis and description generation

```python
# Add GPT-4 Vision analysis
content.add_computed_column(
    image_analysis=openai.chat_completions(
        messages=[{
            'role': 'user',
            'content': [
                {'type': 'text', 'text': content.text},
                {'type': 'image_url', 'image_url': {'url': content.image}},
            ],
        }],
        model='gpt-4o-mini',
    ).choices[0].message.content
)

# Add detailed visual description
content.add_computed_column(
    visual_description=openai.chat_completions(
        messages=[{
            'role': 'user',
            'content': [
                {'type': 'text', 'text': ""Describe this image in detail including:
        1. Main objects and their positions
        2. Colors and lighting
        3. Style and composition
        4. Emotional tone or mood""},
                {'type': 'image_url', 'image_url': {'url': content.image}},
            ],
        }],
        model='gpt-4o-mini',
    ).choices[0].message.content
)

# Add content moderation
content.add_computed_column(
    safety_check=openai.chat_completions(
        messages=[{
            'role': 'user',
            'content': [
                {'type': 'text', 'text': "Is this image appropriate for all audiences? Explain any concerns."},
                {'type': 'image_url', 'image_url': {'url': content.image}},
            ],
        }],
        model='gpt-4o-mini',
    ).choices[0].message.content
)
```

Multiple GPT-4 Vision use cases with different prompting strategies.


### OpenAI Embeddings for Search

Semantic search with OpenAI embeddings

```python
# Add text embeddings
content.add_embedding_index(
    'image_analysis',
    string_embed=openai.embeddings.using(model='text-embedding-3-small')
)

# Add image embeddings (via descriptions)
content.add_embedding_index(
    'visual_description', 
    string_embed=openai.embeddings.using(model='text-embedding-3-large')
)

# Semantic search across content
search_results = content.select(
    content.title,
    content.image_analysis,
    content.visual_description
).search('products with warm lighting and professional photography', limit=10)

for result in search_results:
    print(f"Title: {result['title']}")
    print(f"Analysis: {result['image_analysis'][:200]}...")
    print("---")
```

Semantic search with automatic indexing and query capabilities.


### Advanced Chat Completions

Conversational AI and content generation

```python
# Add content generation
content.add_computed_column(
    marketing_copy=openai.chat_completion(
        model='gpt-4o-mini',
        messages=[
            {'role': 'system', 'content': 'You are an expert marketing copywriter.'},
            {'role': 'user', 'content': f""
            Based on this image analysis: {content.image_analysis}
            
            Create compelling marketing copy including:
            1. A catchy headline
            2. 3 key selling points
            3. A call-to-action
            
            Target audience: professionals aged 25-45
            ""}
        ],
        max_tokens=300
    )
)

# Add SEO optimization
content.add_computed_column(
    seo_keywords=openai.chat_completion(
        model='gpt-4o-mini',
        messages=[
            {'role': 'system', 'content': 'You are an SEO expert.'},
            {'role': 'user', 'content': f""
            Analyze this content: {content.image_analysis}
            
            Generate:
            1. 10 relevant SEO keywords
            2. Meta description (150 chars)
            3. Title tag suggestions
            ""}
        ]
    )
)
```

Advanced chat patterns for marketing and SEO workflows.


### DALL-E Image Generation

Generate images from content analysis

```python
# Create variations table for generated content
variations = pxt.create_table('content_variations', {
    'source_content_id': pxt.String,
    'generation_prompt': pxt.String
})

# Add DALL-E image generation
variations.add_computed_column(
    generated_image=openai.dall_e_3(
        prompt=variations.generation_prompt,
        size='1024x1024',
        quality='standard',
        style='natural'
    )
)

# Generate variations based on original analysis
content.add_computed_column(
    image_variations_prompt=openai.chat_completion(
        model='gpt-4o-mini',
        messages=[{
            'role': 'user', 
            'content': f""
            Based on this image analysis: {content.image_analysis}
            
            Create 3 DALL-E prompts for similar images with these variations:
            1. Different color scheme
            2. Different style (minimalist, vintage, modern)  
            3. Different composition
            
            Return as comma-separated prompts.
            ""
        }]
    )
)

# Auto-generate variations
import json

def create_variations(row):
    prompts = row['image_variations_prompt'].split(',')
    for i, prompt in enumerate(prompts[:3]):
        variations.insert({
            'source_content_id': str(row['id']),
            'generation_prompt': prompt.strip()
        })

# Process each content item
for row in content.collect():
    create_variations(row)
```
