A Python library for knit_space operations.

KnitSpace LLM Ranker: Automated LLM Testing Harness

KnitSpace is an automated testing harness designed to evaluate and compare the capabilities of various Large Language Models (LLMs) across a diverse set of tasks. It provides a comprehensive framework for researchers and developers to assess LLM performance in areas such as problem-solving, knowledge retrieval, coding proficiency, and safety.

🔑 Key Features

• Multi-LLM Support: Integrates with OpenAI, Google, Cohere, Mistral, and more.
• Diverse Test Suite: Includes mathematical reasoning, coding tasks, knowledge tests (MMLU), long-context, instruction-following, and obfuscation-based tests.
• Elo Rating System: Scores models using task difficulty and a cognitive cost metric ("S-value") for nuanced benchmarking.
• Secure Code Execution: Uses Docker containers to safely execute LLM-generated Python/JS code.
• Text Obfuscation: Tests reasoning under character-mapped distortions.
• Interactive Review: Launch a web-based viewer for test results.
• Extensible: Easily add new LLM providers and new types of tests.

🧱 Core Components

📁 knit_space/models.py

• Unified interface for all LLM providers.
• Abstract Model class + subclasses like OpenAIModel, GeminiModel, etc.
• Manages API initialization, inference calls, and model metadata.

📁 knit_space/tests/

• Contains all test definitions.
• base.py defines:
  • QAItem: A test prompt, answer, and scoring logic.
  • AbstractQATest: Base class for all test sets.
  • TestRegistry: Auto-discovers test modules.
• Includes test types: math, coding, chess, long-context, MMLU, etc.

📁 knit_space/marker.py

• Evaluates model responses.
• Uses QAItem scoring logic and tracks correctness.
• Implements Elo scoring using both test difficulty and S-value.
• Launches Flask server to review test results interactively.

📁 knit_space/utils/code_executor.py

• Runs Python and JS code from models inside Docker safely.
• Accepts test cases (input/output pairs) for correctness validation.

📁 knit_space/obscurers/

• Tools for generating challenging input variants.
• CharObfuscator: Replaces characters using a bijective map to test reasoning under noise.

🐍 verify-auto.py

• Main script to run tests.
• Configures model, loads test classes, and executes tests.
• Starts web server for results review.

⚙️ Setup

1. Prerequisites

• Python 3.8+
• Docker (for coding tasks)
• Git

2. Installation

git clone [<repository_url>](https://github.com/C-you-know/Action-Based-LLM-Testing-Harness)
cd KnitSpace-LLM-Ranker

python -m venv venv
source venv/bin/activate  # (Windows: venv\Scripts\activate)

pip install -r requirements.txt  # Or manually install dependencies

3. API Key Setup

Set the following environment variables based on the providers you wish to use:

export OPENAI_API_KEY="..."
export GEMINI_API_KEY="..."
export MISTRAL_API_KEY="..."
export COHERE_API_KEY="..."
# Cloudflare-specific
export CLOUDFLARE_API_KEY="..."
export CLOUDFLARE_ACCOUNT_ID="..."

🚀 Running Tests

Run via verify-auto.py

1. Configure:

   • Choose model/provider in verify-auto.py
   • Select tests in test_cases list

2. Run:

   python verify-auto.py
   

3. View:

   • Console logs test stats
   • Web UI opens at http://localhost:8000

Debug Test Inputs (optional)

Use QA-test.py to inspect generated test data without invoking an LLM:

python QA-test.py

🔌 Extending the Harness

➕ Adding New LLM Providers

1. Subclass Model in knit_space/models.py

2. Implement:

   • _initialize_client()
   • inference(...)

3. Update:

   • PROVIDER_CLASS_MAP
   • _get_api_key_for_provider() and optionally _list_api_models()

🧪 Adding New Test Types

1. Create a new file in knit_space/tests/
2. Subclass AbstractQATest
3. Implement generate() to yield QAItems
4. Optionally register using @register_test()
