Clef is a 27B multimodal model that turns a state and a schema of typed questions into decisions. It reads the state as text, JSON, images, or video, and returns a probability for every allowed option of every question in a single forward pass.


Kev is a family of small decision models built on Qwen3.5 and based on the architecture described in Jev's Architecture Unmasked. You can use the pretrained weights or train your own. The API matches TypeSafe's System One, so you can point their Python SDK at your local...



SubQ Snap is a multimodal decision model built for fast, long-context decisions in enterprise agentic workflows.

JevModel is an independent browser workbench for running structured decision questions with the Jev model. Users enter text or JSON and choose Choice, Score or Noul to obtain structured probability results.


Strom is a decision model that interprets plain-language queries about text, images, or video, and provides responses such as yes/no, a choice, or a score with probabilities in under 200 ms. Its operation cost is 20-71 times lower than a chat model.
