stampr-ai 0.1.0a11

Live verification of AI model signatures to detect model changes

stampr_ai

Live verification of AI model signatures to detect model changes and ensure consistent AI behaviour.

Installation

pip install stampr-ai

Setup

import os
os.environ['OPENAI_API_KEY'] = "your_openai_api_key_here"
os.environ['OPENROUTER_API_KEY'] = "your_openrouter_api_key_here"
os.environ['HF_TOKEN'] = "your_huggingface_token_here"

Quick Start

Install stampr_ai and run verification:

pip install stampr_ai

# CLI usage - most recent signature only
stampr gpt-4o:now OpenAI

# CLI usage - past 4 days (more robust)
stampr gpt-4o:latest OpenAI

# Or with explicit API key
stampr gpt-4o:latest OpenAI --api-key $OPENAI_API_KEY

Python Usage

OpenAI Example

from stampr_ai import verify_model
import os

# Verify model matches a specific signature hash
result = verify_model("gpt-4o:bede20", "OpenAI", os.environ['OPENAI_API_KEY'])

if result['verified']:
    print("Signature Verified.")
else:
    print("Signature mismatch!")
print(f"Expected: {result['live_verification_result']['expected_tokens']}")
print(f"Actual: {result['live_verification_result']['actual_tokens']}")

OpenRouter Example

from stampr_ai import verify_model
import os

# OpenRouter example - robust verification
result = verify_model("Llama4_17b:latest", "OpenRouter/Parasail", os.environ['OPENROUTER_API_KEY'])

if result['verified']:
    print("Signature Verified.")
else:
    print("Signature mismatch!")
print(f"Expected: {result['live_verification_result']['expected_tokens']}")
print(f"Actual: {result['live_verification_result']['actual_tokens']}")
