Jevper – the Jev interface on top of any OpenAI-compatible model

In plain words

Jevper is a classification wrapper that works with OpenAI-compatible models to return probabilities and confidence scores instead of text responses. It implements a TypeSafe System One approach for structured output. The tool is designed for developers who need categorical predictions with quantified certainty levels from language models rather than prose-based answers.
