Jev projects & practices

1,800-point launch thread whose ~480 comments debate whether typed decisions replace LLM calls for classification, routing, and verification.

the 63k-like announcement from TypeSafe's founder arguing RLCD-trained decision models are a shorter path to economic value than chat models.

948-like demo where Jev decides which model should serve a request before it is forwarded.

builder reports that a small MLP trained on top of Qwen 4B already reproduces Jev-like decision behaviour.

attempt at running a Jev-style decision model locally, with speed noted as still improvable.

test report using Jev to check each agent action first, reportedly catching most attacks with almost no false blocks and much lower latency.

argues that purely engineering decisions in security work belong to Jev rather than a chat model.

public Convex-backed demo inviting one million judged questions instead of generated answers.

a shipped Mac app routes setup and troubleshooting questions to Jev when no language model is loaded.

explains the System One category to Chinese readers as a calibrated, typed decision layer for code.

launch thread framing Jev as a low-hallucination, low-cost decision model for software rather than chat.

builders describe using Jev as an agent tool-use safety layer and planning a prompt-complexity model router.

work-in-progress demo of Jev driving Minecraft, including fleeing zombies at night, as a test of fast structured decisions.
