# AI Diplomacy Analysis Documentation

## Executive Summary

This repository contains comprehensive analysis tools for evaluating AI model performance in Diplomacy games. Through hundreds of experiments with 62+ unique AI models over 4000+ games, we've developed insights into how AI agents have evolved from passive, defensive play to active, strategic gameplay.

## Core Research Questions

### 1. Evolution of AI Strategy
**Question**: Have AI models evolved from passive (hold-heavy) to active (move/support/convoy) strategies?

**Finding**: Yes. Our analysis shows a clear trend from ~80% hold orders in early models to <40% holds in recent models, demonstrating strategic evolution.

### 2. Success Rate Importance
**Question**: Do active orders correlate with better performance?

**Finding**: Models with higher success rates on active orders (moves, supports, convoys) consistently outperform passive models. Top performers achieve 70-80% success rates on active orders.

### 3. Scaling Challenges
**Question**: Does performance degrade as unit count increases or games progress?

**Finding**: Yes. Most models show degraded performance when controlling 10+ units, confirming the complexity scaling hypothesis. Only a few models (o3, gpt-4.1) maintain performance at scale.

## Data Architecture

### Game Data Structure
```
results/
├── YYYYMMDD_HHMMSS_description/
│   ├── lmvsgame.json          # Complete game data (REQUIRED for completed games)
│   ├── llm_responses.csv      # Model responses and decisions (SOURCE OF TRUTH)
│   ├── overview.jsonl         # Game metadata
│   └── general_game.log       # Detailed game log
```

### Key Data Formats

#### New Format (2024+)
- Results stored in `order_results` field, keyed by power
- Success indicated by `"result": "success"`
- Orders categorized by type (hold, move, support, convoy)

#### Old Format (Pre-2024)
- Orders in `orders` field, results in `results` field
- Results keyed by unit location (e.g., "A PAR", "F LON")
- Success indicated by empty value (empty list, empty string, or None)
- Non-empty values indicate failure types: "bounce", "dislodged", "void"

## Analysis Pipeline

### 1. Data Collection
- **Source of Truth**: `llm_responses.csv` files contain actual model names
- **Completed Games Only**: Only analyze games with `lmvsgame.json` present
- **Model Name Extraction**: Direct from CSV, no normalization needed

### 2. Performance Metrics

#### Order Types
- **Hold**: Defensive/passive orders
- **Move**: Unit movement orders
- **Support**: Supporting other units
- **Convoy**: Naval convoy operations

#### Key Metrics
- **Active Order Percentage**: (Move + Support + Convoy) / Total Orders
- **Success Rate**: Successful Active Orders / Total Active Orders
- **Unit Scaling**: Performance vs number of units controlled
- **Temporal Evolution**: Changes over game decades (1900s, 1910s, etc.)

- Model comparison matrix
- Phase and game participation counts

## Technical Implementation

### Critical Bug Fixes

#### 1. Old Format Success Calculation
**Problem**: Old games store results by unit location, not power name
**Solution**: Extract unit location from order string and lookup results

```python
# Extract unit location (e.g., "A PAR - PIC" -> "A PAR")
parts = order_str.strip().split(' ')
if len(parts) >= 2 and parts[0] in ['A', 'F']:
    unit_loc = f"{parts[0]} {parts[1]}"

# Check results using unit location
if unit_loc in results_dict:
    result_value = results_dict[unit_loc]
    if isinstance(result_value, list) and len(result_value) == 0:
        # Empty list means success
```

#### 2. CSV as Source of Truth
**Problem**: Model names have various prefixes in different files
**Solution**: Use only CSV files for model names, ignore prefixes

### Best Practices

#### Data Processing
1. Always check for `lmvsgame.json` to identify completed games
2. Read entire CSV files, not just first N rows
3. Handle both old and new game formats
4. Use pandas for efficient CSV processing

#### Visualization Design
1. **Colors**: Use colorblind-friendly palette
2. **Labels**: Include counts and percentages
3. **Sorting**: Always sort for clarity (by performance, activity, etc.)
4. **Filtering**: Apply minimum thresholds for statistical significance
5. **Annotations**: Add context with titles and axis labels

## Key Findings

### Model Performance Tiers

#### Tier 1: Elite Performers (>70% success rate)
- o3 (78.8%)
- gpt-4.1 (79.6%)
- x-ai/grok-4 (74.2%)

#### Tier 2: Strong Performers (60-70% success rate)
- gemini-2.5-flash (71.8%)
- deepseek-reasoner (68.5%)
- Various llama models

#### Tier 3: Developing Models (<60% success rate)
- Earlier versions and experimental models
- Often show high activity but lower success

### Strategic Evolution Patterns
1. **Early Phase**: High hold percentage (70-80%), defensive play
2. **Middle Phase**: Increasing moves and supports (50-60% active)
3. **Current Phase**: Sophisticated multi-order strategies (60-80% active)

### Scaling Insights
- Performance peak: 4-8 units
- Degradation point: 10+ units
- Exception models: o3, gpt-4.1 maintain performance

## Usage Guide

### Running the Analysis
