Hi everyone!
The difficult part of moderation is deciding where a product wants to draw the line.
A kids app, a cybersecurity tool, and a mental-health platform can look at the same content very differently. Shieldstral lets you express that policy as a plain-language question at inference time, rather than relying on a fixed set of categories baked into the model.
Ask “Is this image safe for minors?” or “Does this response promote physical violence?” and the same 3B checkpoint can score text, images, or both.
It runs on one 16GB GPU, and weights are available under Apache 2.0. Teams can keep the moderation layer local and change the policy without training a new model each time.
