Why Use a Dedicated Llama Detector?
Meta's Llama series is the most widely deployed open-source large language model family, powering thousands of applications and fine-tuned variants worldwide. Plagly.ai's Llama Detector identifies text from Llama 3, Llama 4, and popular fine-tuned derivatives. Because Llama models are open-source and frequently customized, detecting their output requires analysis that goes beyond surface-level patterns. Our engine examines deep statistical signatures shared across the Llama model family — token distribution characteristics, grammatical preferences, and structural tendencies — that persist even after fine-tuning. This makes Plagly effective at detecting Llama-generated text whether it came from a stock deployment or a specialized, domain-specific variant.

How to Spot Llama Writing
Common tells that a passage was generated by Meta Llama (3 & 4):
- Repetitive connectors — "additionally," "furthermore," "in addition."
- Occasionally stilted or over-explained phrasing.
- Reliable structure but a flatter, less distinctive voice.
- Restates the same point in two slightly different ways.
- Fine-tuned variants shift tone, but the underlying pattern persists.
