Last Layer
last_layer is a security library designed to protect LLM applications from prompt injection attacks, jailbreaks, and exploits. It acts as a robust filtering layer to scrutinize prompts before they are processed by LLMs, ensuring that only safe and appropriate content is allowed through.
Key Features
- Ultra-fast scanning ⚡: Achieves >=2ms latency for prompt injection/jailbreak scanning on CPU, ensuring minimal impact on user experience.
- Privacy-focused 🔒: Operates without tracking or making network calls, ensuring data stays within your infrastructure with a package size under 50 MB.
- Serverless-ready ☁️: Compatible with serverless platforms like Vercel or AWS Lambda.
- Advanced detection mechanisms 🕵️♂️: Utilizes a combination of a closed, pruned AutoML model, heuristic analysis, and regular expression datasets to accurately identify threats with 92% accuracy based on internal testing.
- Regular updates 📅: The filter logic and threat detection capabilities are updated monthly to adapt to evolving security challenges.
This library is designed as a safety tool, significantly reducing the risk of prompt-based attacks and exploits, while acknowledging that it does not guarantee complete protection against all possible threats.
