MODEL PROFILE

ModernGuard-1

guardion · ModernGuard-1

> TL;DR: A state-of-the-art multilingual prompt injection classifier achieving 94.3% F1 score with industry-leading 30ms latency, 20x faster than cloud alternatives, trained on a large corpus of attacks, capable of detecting both explicitly malicious prompts as well as data that contains injected inputs. ModernGuard-1 is a state-of-the-art, cheaper and faster multilingual classifier designed by GuardionAI for real-time detection of prompt injections and jailbreak attempts. Built on the ModernBERT architecture, the model provides industry-leading latency for securing LLM-based applications across over 1,080 languages, making it one of the fastest and most linguistically diverse safety classifiers available. **Context Window:** Supports up to 8,192 tokens (2,048 tokens recommended for optimal real-time performance)

Frequently asked questions

Do open weights permit free commercial use?

Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.

Are these real-time billing prices?

These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
