We’re excited to introduce Lumma-fev-0.6B, a Jev-like decision model fine-tuned on our from-scratch Lumma-0.6B-Base You give it a document and a set of typed questions, and it returns a probability for every answer in one forward pass. It generates no text, so there's nothing to parse and nothing to hallucinate. It's built for routing, triage, moderation and any workflow that needs a decision rather than a paragraph Try it: https://huggingface.co/FrontiersMind/Lumma-fev-0.6b And this is just the beginning, we’re planning to open-source 4B and 9B versions with a detailed benchmark report in the coming couple of days
