Description
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. There is no free-form text generation and no output parsing. The Clef API is fully compatible with Jev and SystemOne.

Could you build this?
No Clef is a 27B multimodal foundation decision model trained to perform classification over schema constraints in a single forward pass.
What it would actually take: This requires multi-million dollar compute clusters, large-scale multimodal pre-training datasets, novel neural network architecture modifications (constrained classification heads across state and schemas without generative decoding), and advanced distributed training engineering (e.g., Megatron-LM/DeepSpeed) run by ML research scientists.
