Project Description

AI Benchmark Repository

A specialized testing suite for evaluating Large Language Models (LLMs) on spatial reasoning tasks through gradient scoring systems.

🚀 Quick Start

# Install dependencies
pip install -r requirements.txt

# Run benchmark on LLM output file
python run_benchmark.py --input path_to_llm_output.txt

# Run benchmark against an OpenRouter model
python run_benchmark.py --model google/gemini-2.0-flash-exp:free --benchmark maze

# Run and save to leaderboard
python run_benchmark.py --input llm_output.txt --add-to-leaderboard

# View the leaderboard
python run_benchmark.py --leaderboard

# Run all models from models.txt
python run_benchmark.py --run-all

OpenRouter Setup

Set your API key as an environment variable:

# Windows
set OPENROUTER_API_KEY=your_key_here

# Linux/Mac
export OPENROUTER_API_KEY=your_key_here

🏆 Leaderboard System

The benchmark includes a leaderboard to track and compare model performance:

• Add results: Use --add-to-leaderboard when running benchmarks
• View rankings: Use --leaderboard to display current standings
• Persistent storage: Results saved to leaderboard.json

🧪 Current Benchmarks

The "Maze Gauntlet" - LLM Spatial Reasoning Challenge

Unlike traditional maze benchmarks that use binary pass/fail scoring, the Maze Gauntlet implements a Gradient Scoring system that evaluates how well LLMs can generate complex, solvable mazes with specific state-dependency rules.

Philosophy

Most maze benchmarks are binary (Pass/Fail). This is a Gradient Benchmark that rewards: - Ambition: Grid size and complexity - Logic: Proper S → K → D → E path progression
- Danger: Strategic trap placement adjacent to valid paths

📊 Scoring System

The Maze Gauntlet Scoring Components:

1. Ambition (Grid Size)
2. Points: 100 × log₂(Rows × Cols)

3. Rewards larger mazes but with logarithmic scaling to prevent exponential runaway

4. Progress (Path Logic)

5. 2 points per reachable tile
6. +50 bonus for Key ('K')
7. +50 bonus for Door ('D')

8. +50 bonus for End ('E')

9. Path Efficiency (New)

10. Points: (Shortest Valid Path Length / Grid Size) × 100

11. Rewards mazes that use the available space efficiently for the solution

12. Danger (Strategic Placement)

13. Points: 20 × sqrt(Adjacent Traps)
14. Diminishing returns preventing "trap spamming"

15. Only traps near the valid solution path count

16. Logic Penalties

17. If Traps > Walls: -50% score penalty

18. Path must follow S → K → D → E sequence

19. Proximity Bonuses

20. Partial credit for unreachable objectives based on distance to reachable areas

21. No double-counting for reached objectives

22. Constraints

23. Maximum maze size: 64×64 (mazes exceeding this limit score 0)

🎯 Adding New Benchmarks

This repository is designed to be modular. To add new benchmarks:

1. Create a new directory under benchmarks/
2. Implement an evaluator function
3. Add a prompt.md file with the benchmark prompt
4. Update the CLI in run_benchmark.py to include your new benchmark

📝 Example Usage

# Run the Maze Gauntlet benchmark on a file
python run_benchmark.py --input sample_llm_output.txt

# Add benchmark results to leaderboard
python run_benchmark.py --input sample_llm_output.txt --add-to-leaderboard

# Get JSON output
python run_benchmark.py --input sample_llm_output.txt --json

# Test a specific model from models.txt
python run_benchmark.py --model google/gemini-2.0-flash-exp:free --benchmark maze

# Test a different model
python run_benchmark.py --model meta-llama/llama-3.3-70b-instruct:Free --add-to-leaderboard

# Run all models from models.txt
python run_benchmark.py --run-all --sequential

The output will be a detailed JSON report showing your score breakdown.
