Semantic ifs from open models, on a 3090 at home. Independent; not affiliated with Jev or TypeSafe.

SemIf is an open-source Python project that lets software make small semantic decisions (routing, retries, yes/no checks) using open LLMs like a 4B Qwen model, reading typed option probabilities directly instead of generating and parsing text. It reproduces the interface pattern of TypeSafe's closed Jev service and runs locally on a consumer GPU, Apple Silicon, or even CPU, with a browser demo.

Why now: It's trending as a popular open-source alternative to TypeSafe's closed Jev service — recently renamed from OpenJev, with active development, a no-waitlist browser demo, and 4.3k stars within a week of creation.

Who it is for: Developers who want local, fast, structured AI-driven decision points in their software without waiting on proprietary APIs.
