Jev in 25 Lines of Python: Local LLM Classification

Hacker News •
×

Everyone is talking about Jev as the next AI frontier, but the author demonstrates it in just 25 lines of Python using a local GGUF model. The script loads Qwen/Qwen3-0.6B-GGUF via llama-cpp-python, defines classification choices (Legitimate, Spam, Phishing), and extracts logits for each option token. It then converts logits to probabilities using numpy's logaddexp for numerical stability.

The example shows Phishing at 0.885 probability. The author argues Jev is simply local classification with calibrated probabilities — fast, private, no API calls, no synthetic data, no RLCD training. They note this is a parody and link to more complete open implementations: Open Jev, openjev-sglang, and Open Jev on Diffusion Gemma.
