JevModel

JevModel (jevmodel.app) is an AI decision workbench that compares model answers side by side, so teams can test prompts, review differences, and choose the best model result. Founders, analysts, developers, and product teams use it to get structured Choice, Score, and Nous-style answers to real decisions, run batches over many inputs at once, and call the Jev API from their own apps and scripts.

JevModel runs in the browser with no installation. A free tier covers everyday use, and paid plans add higher limits and API throughput through a monthly token allowance. Unused tokens roll over to the next month, and failed requests are not charged.

How JevModel Works

Users enter a prompt or a real decision and see model answers laid out side by side, which makes it easy to spot differences and pick the strongest result. Answers can come back in structured formats such as Choice, Score, and Nous. For larger jobs, batch runs process many inputs at once, and the Jev API lets developers call the same capabilities from their own apps and scripts. Usage is metered in tokens: the console, batch runs, and API share one balance. On paid plans, Decision Flows are unlimited, batches can reach 1,000 rows, and flows bill only for the branches that actually run.

Who Should Use JevModel?

Founders, analysts, developers, and product teams who need to compare model outputs before committing to one are the clearest fit. Individuals can try it on the free tier, while Starter suits prototypes and Builder suits a first production feature. Pro and Scale are aimed at apps with steady traffic and teams running large batch jobs across several features. Because tokens roll over and failed requests are not charged, it also works for teams with uneven monthly usage.
