Meta Releases Llama AI Open Source Protection Tools

Facebook parent company Meta on Tuesday announced the release of new open source Llama AI protection tools, along with new AI-enabled solutions for security operations.

The new tools available now for the open source AI community include Llama Guard 4, LlamaFirewall, and Llama Prompt Guard 2.

Intended as a unified safeguard across modalities and providing support for text and image understanding protections, Llama Guard 4 is also available on a new Llama API, which was released in preview.

LlamaFirewall is a fresh security tool for orchestration across guard models that can detect and prevent prompt injections, insecure code, and risky plug-in interactions. It supports existing Meta protection tools, to help developers build secure AI systems.

The updated Llama Prompt Guard classifier model brings improved jailbreak and prompt injection detection, and is accompanied by Prompt Guard 2 22M, a lightweight version for reduced latency and compute costs.
