Explainers

  • Decision model vs LLM: Decision models (OpenAI Decisions, Microsoft-Decision-1, Jev, Perplexity pplx-decider) return probabilities for options you define and bill input tokens only; LLMs with structured output return a label or JSON with no documented probability. Verified prices, a 1M-ticket cost example, and when to use each.
  • Jev Router (OpenRouter): typesafe/jev-router uses TypeSafe’s Jev decision model to pick a model and reasoning effort for each OpenRouter request. No fee of its own: you pay the routed model’s price. Plugin options, cost tiers, limits, and how it differs from OpenRouter’s Auto Router, checked 2026-10-28.
