# LLM-Enhanced Blog Analysis System - Implementation Plan

## Executive Summary
Enhancement of the existing blog analysis system to leverage LLMs for deeper content understanding, using Claude Sonnet 3.5 for high-volume classification and Claude Opus 4.1 for strategic synthesis.

## Current State Analysis

### Existing System Limitations
- **Topic Coverage**: Only 8 pre-defined categories via keyword matching
- **Semantic Understanding**: Zero - misses context, synonyms, and related concepts
- **Topic Diversity**: Captures ~20% of actual content diversity
- **Cost**: $0 (pure regex matching)
- **Processing**: 30 seconds for full analysis

### Discovered Insights
- **Content Volume**: 2000+ items per competitor across YouTube + Instagram
- **Actual Diversity**: 100+ unique technical terms per sample
- **Missing Intelligence**: Brand mentions, product trends, emerging topics

## Proposed Architecture

### Two-Stage LLM Pipeline

#### Stage 1: Sonnet High-Volume Classification
- **Model**: Claude 3.5 Sonnet (cost-efficient)
- **Purpose**: Process 2000+ content items
- **Batch Size**: 10 items per API call
- **Cost**: ~$0.50 per full run

**Extraction Targets**:
- 50+ technical topic categories (vs current 8)
- Difficulty levels (beginner/intermediate/advanced/expert)
- Content types (tutorial/troubleshooting/theory/product)
- Brand and product mentions
- Semantic keywords and concepts
- Audience segments (DIY/professional/commercial)
- Engagement potential scores

#### Stage 2: Opus Strategic Synthesis
- **Model**: Claude Opus 4.1 (high intelligence)
- **Purpose**: Strategic analysis of aggregated data
- **Cost**: ~$2.00 per analysis

**Strategic Outputs**:
- Market positioning opportunities
- Prioritized content gaps with business impact
- Competitive differentiation strategies
- Technical depth recommendations
- 12-month content calendar
- Cross-topic content series opportunities
- Emerging trend identification

## Module Specifications

### 1. SonnetContentClassifier
```python
class SonnetContentClassifier:
    """High-volume content classification using Claude Sonnet 3.5"""
    
    Methods:
    - classify_batch(): Process 10 items per API call
    - extract_technical_concepts(): Deep technical term extraction
    - identify_brand_mentions(): Product and brand tracking
    - assess_content_depth(): Difficulty and complexity scoring
```

### 2. OpusStrategicSynthesizer
```python
class OpusStrategicSynthesizer:
    """Strategic synthesis using Claude Opus 4.1"""
    
    Methods:
    - synthesize_competitive_landscape(): Full market analysis
    - generate_blog_strategy(): 12-month strategic roadmap
    - identify_differentiation_opportunities(): Competitive positioning
    - predict_emerging_topics(): Trend forecasting
```

### 3. LLMOrchestrator
```python
class LLMOrchestrator:
    """Cost-optimized pipeline controller"""
    
    Methods:
    - determine_processing_tier(): Route content to appropriate processor
    - manage_api_rate_limits(): Prevent throttling
    - track_token_usage(): Cost monitoring
    - fallback_to_traditional(): Graceful degradation
```

## Cost Optimization Strategy

### Tiered Processing Model
1. **Tier 1 - Full Analysis** (Sonnet)
   - HVACRSchool blog posts
   - High-engagement content (>5% engagement rate)
   - Recent content (<30 days)

2. **Tier 2 - Light Classification** (Sonnet with reduced tokens)
   - Medium engagement content (2-5%)
   - Older but relevant content

3. **Tier 3 - Traditional** (Keyword matching)
   - Low engagement content
   - Duplicate or near-duplicate content
   - Cost fallback when budget exceeded

### Budget Controls
- **Daily limit**: $10 for API calls
- **Per-analysis budget**: $3.00 maximum
- **Automatic fallback**: Switch to traditional when 80% budget consumed

## Expected Outcomes

### Quantitative Improvements
| Metric | Current | Enhanced | Improvement |
|--------|---------|----------|-------------|
| Topics Captured | 8 | 50+ | 525% |
| Semantic Coverage | 0% | 95% | New capability |
| Brand Tracking | None | Full | New capability |
| Processing Time | 30s | 5 min | Acceptable |
| Cost per Run | $0 | $2.50 | High ROI |

### Qualitative Improvements
- **Context Understanding**: Captures "capacitor testing" not just "electrical"
- **Trend Detection**: Identifies emerging topics before competitors
- **Strategic Insights**: Business-justified recommendations
- **Content Series**: Identifies multi-part content opportunities
- **Seasonal Planning**: Calendar-aware content scheduling
