SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prevents unauthorized replication of proprietary models through API abuse. Unauthenticated or unthrottled inference endpoints enable attackers to query a model and potentially distill a clone, risking IP loss and exposure of business logic.

Core Features & Use Cases

  • Enforces authentication on all inference endpoints to ensure only authorized clients can query the model.
  • Applies per-user or per-API-key rate limits and monitors for extraction patterns to detect abuse.
  • Strips sensitive signals from responses (e.g., logprobs, embeddings) and logs metadata for after-the-fact investigation.
  • Use Case: Deploying an LLM service in production where protecting IP and preventing model theft is critical.

Quick Start

Integrate model-theft protections by enabling API key authentication, per-user rate limiting, and safe response handling on your inference endpoints.

FAQPage Schema
How do I prevent unauthorized model cloning through API abuse?

To prevent unauthorized model cloning through API abuse, enforce API key authentication on inference endpoints to ensure only authorized clients can query your proprietary models.

What is the best way to secure LLM inference endpoints against model theft?

Securing LLM inference endpoints against model theft requires applying per-user rate limits, stripping sensitive signals like logprobs from responses, and logging metadata to detect extraction patterns.

How does rate limiting protect proprietary models from being distilled?

Rate limiting protects proprietary models from being distilled by restricting per-user or per-API-key query volumes, preventing attackers from gathering enough data to train a clone.

Do I need API authentication to protect my production LLM service?

Yes, API authentication is required to protect production LLM services, ensuring only authorized clients can access inference endpoints and mitigating the risk of intellectual property loss.

Why should I strip logprobs and embeddings from API responses?

Stripping logprobs and embeddings from API responses prevents attackers from extracting sensitive internal signals that could be used to replicate your proprietary business logic or model weights.

When should I monitor API logs for extraction patterns?

You should monitor API logs for extraction patterns whenever deploying an LLM service in production, enabling after-the-fact investigation of suspicious query behaviors that threaten model IP.
