About Umbris

Umbris is where people learn to test AI language models: how they fail, how to probe them safely, and how to write up what they find.

Umbris aims to give people the knowledge, tools and connections to take on LLMs.

We're not here for profit. We're a knowledge hub built by a community, for a community. The only fee is curiosity.
