open-jev
open-jev is a browser-focused TypeScript library for typed decisions: one piece of text (the state) plus any number of typed questions go in, and one forward pass returns a calibrated probability distribution per question. Nothing is generated, so an answer is always one of the options you provided.

Could you build this?
Partial While wrapping browser-based ONNX runtimes in TypeScript is vibe-codeable, building a custom calibrated single-forward-pass classification head with proper calibration metrics requires ML research and training expertise.
What it would actually take: The architecture involves an in-browser WebGPU/ONNX Runtime engine paired with a quantized encoder model (like ModernBERT or DeBERTa) structured to output multi-target calibrated logits in a single inference pass. The hard parts are model training, temperature scaling/conformal prediction calibration across diverse question sets, and WebGPU memory budget optimization.
