Llama Guard 3 8B

Llama Guard 3 8B is Meta's content safety classifier designed to detect and evaluate harmful content in user prompts and model outputs.

Strengths

It efficiently identifies unsafe content across a range of harm categories with a compact 8-billion-parameter footprint.

Best for

Content moderation pipelines and safety filtering in production systems that need fast, lightweight classification.

Limitations

It has been superseded by Llama Guard 4 12B (released 2025-04), which offers improved detection capabilities; this earlier version should be considered for deployment only if model size or latency constraints outweigh the need for newer safety performance.
