Mistral's Shieldstral Packs Big-Model Safety Into a 3-Billion-Parameter Package
Mistral has released Shieldstral, a 3-billion-parameter open-weight safety classifier that matches the performance of much larger models on text safety benchmarks and sets a new high score for joint text and image classification. The model uses a runtime-definable yes/no question format, allowing operators to write custom screening rules in plain language. Shieldstral is designed to be fast and cost-effective, making it practical for real-time content moderation.
