Description
Jev is TypeSafe AI's first System One frontier model: unstructured state in, typed probabilistic decisions out. Instead of generating text, Jev returns Choice, Score, and Noul answers with calibrated probabilities your code can act on. Parallel sampling delivers ~70-500ms responses, about 20-200x faster and 40-400x cheaper than comparable LLM workflows, with output tokens free. Early access via the waitlist on typesafe.ai.

Could you build this?
No Jev is a proprietary frontier neural network trained specifically for probabilistic decision outputs rather than text generation, demanding fundamental AI research and GPU training clusters.
What it would actually take: Building this requires designing a custom neural network architecture with calibrated classification heads instead of generative autoregressive decoding, collecting and curating massive domain-specific decision datasets, and training on high-performance GPU clusters. Serving it at sub-500ms parallel latencies requires custom inference kernels (Triton/CUDA) and specialized model quantization.
