Probabilistic Router
A routing mechanism that uses probabilistic inference to direct inputs to appropriate downstream models or handlers, optimizing for latency, cost, or accuracy without deterministic rule-based branching.
Core Concepts
- System 1 vs System 2: Distinguishes between fast, intuitive routing (System 1) and slow, deliberative reasoning (System 2).
- LLM Orchestration: Managing multiple models to handle complex workflows efficiently.
- Type Safety: Ensuring routing decisions adhere to strict schema constraints to prevent runtime errors.
Jev: TypeSafe AI’s System 1 Probabilistic Router
Jev is a specialized “System 1 model” developed by typesafe-ai designed to act as an intelligent router for LLM Orchestration. Unlike generative models, Jev focuses on rapid, probabilistic decision-making.
- Function: Acts as a high-speed router rather than a text generator.
- Architecture: Built on gemini-25-flash API for low-latency inference.
- Key Feature: Provides TypeSafe routing decisions, ensuring outputs match expected schemas.
- Use Case: Ideal for Summary modes and high-throughput orchestration tasks.
