Codex Reset Radar is a web dashboard that helps developers track Codex usage limits and uncertain reset windows. It shows the current usage-limit and reset status, keeps 26 weeks of reset history so past patterns stay visible, and surfaces public reset announcements from Tibo beside the measured data. Predictions are presented as evidence-based likelihoods rather than exact countdowns, and stale or missing signals are called out instead of being smoothed over, so a developer can decide whether to continue a heavy AI coding session, pause, or move to work that does not depend on the next reset window. It runs in the browser, is free to read, and requires no installation or account.

JevModel is an independent, bilingual guide and browser workbench for TypeSafe's Jev decision model, aimed at developers and product teams who need a judgment their code can act on. Instead of free-form prose, Jev returns a typed answer: one choice from a set you define, a score on a scale, or the probability that a statement is true. The Jev Workbench ships ten editable workflow presets covering support routing, lead scoring, agent action gating, incident triage, release readiness and more; edit the state and questions and run a real decision in the browser. Each account gets five free runs per UTC day plus a one-time 100K token grant. Thirty-plus guides cover the API, question types, access paths, comparisons with LLM prompts and rules engines, and evaluation.

Jev Model is a System One decision model for developers. It accepts shared state as text, JSON objects, or arrays of text and answers up to eight Choice, Score, or Noul questions in parallel, returning structured outputs with probabilities that applications can use for classification, routing, scoring, guardrails, and human-review workflows. The website provides a free unlimited online playground, documentation, API access, and paid access plans.

Playground for Jev and Laya System One models — classify text, route intents, score inputs, and test LLM guardrails with structured judgments. Free signup includes 1,000,000 input tokens with no credit card.

Typed AI decisions for software: send application state and get a choice, score, or yes/no probability your code can branch on.
