Jevper - Typed classification wrapper for OpenAI-compatible models
Show HN: Jevper – the Jev interface on top of any OpenAI-compatible model
Jevper brings the Jev (TypeSafe System One) interface to any OpenAI-compatible model, turning free-form LLM prose into structured, typed answers with probabilities and confidence. Define questions as Noul, Choice, or Score, and get back choices, probability distributions, and confidence scores—no hosted TypeSafe API required. It works with hosted LLMs or self-hosted llama.cpp servers, supports logprobs, grammar, structured, and discrete methods, and adds reasoning traces and few-shot examples. Install with pip install jevper and keep your Jev code unchanged.
Same call as typesafe-sdk, different backend: point jevper at a hosted LLM or a self-hosted llama.cpp server and code written for Jev keeps working, unchanged.
