SemIf

SemIf, formerly OpenJev, is an independent research project for making small semantic decisions with open language models. Instead of generating text and parsing it afterward, it reads probabilities directly from declared answer options. Each request supplies state, a runtime-defined question, and typed choices, allowing the model to behave like a semantic conditional. Shared-state execution can reuse a long context across many related decisions to reduce repeated computation. Backends include CUDA, Apple MLX and MPS, CPU execution through llama.cpp, and an experimental EXL3 bridge for larger models. The project includes calibration, benchmarks, reproducible fixtures, raw results, and browser demonstrations. It reproduces an interface pattern similar to Jev but does not reproduce Jev's private model or training.
