Jev (jev-latest) is TypeSafe AI’s brand-new, first cutting-edge large model built on the System One architecture, designed for advanced decision-making and structured evaluation. As an innovative model that breaks away from the traditional token-by-token generation paradigm, Jev is specifically tailored for high-concurrency software decision-making, intelligent routing, automated risk control, and real-time workflow branching. The model does not output any natural language text; instead, it takes unstructured program states as input and directly produces well-defined, strongly typed data along with precisely calibrated probabilities in a single, parallel pass. Thanks to its extreme parallel sampling and type constraints, Jev boasts zero hallucinations, zero JSON parsing errors, and inference speeds that are 40 to 200 times faster than those of conventional LLMs, making it an ideal tool for rapid software system integration and low-latency agent conditional branching.

Core Capabilities

Single-Step Parallel Ultra-Fast Response (70ms - 500ms): Abandoning the token-by-token autoregressive text generation approach, Jev adopts a single-step parallel query that outputs typed data directly, achieving inference speeds 40 to 200 times faster than conventional LLMs—perfectly suited for real-time interactive workflows.

Native Type Safety and 0% Hallucination Rate: The output results are strictly constrained by the schema types predefined by the user, mathematically eliminating type errors and field hallucinations.

Precisely Calibrated Confidence Levels: Each decision output comes with highly accurate probability values (ranging from 0% to 100%). Developers can easily set confidence thresholds: high-confidence decisions are automatically executed, while low-confidence decisions are routed to human operators or fallback models, greatly enhancing the reliability of automated systems.

Extremely Low Computational Overhead: Since no massive output token stream is generated, Jev not only consumes minimal time but also offers overwhelmingly competitive pricing.
