Read from X on 24 Sep 2026. Counts change daily.

Wayne Sutton’s Ask Jev is a public site where you type a question and Jev judges it rather than answering it. The site is built with Convex, and Sutton invites people to help get it to a million questions.

The site’s description today says Jev returns yes, no, or it depends in about 100 milliseconds. Signed-in users also get a short answer: Jev picks one of four models, and the answer streams through the Convex AI Gateway. Every question lands on a realtime wall that counts toward the million.

Introducing System One Models and Jev (Hacker News launch thread)

The 1,978-point, 513-comment launch thread. The top comment calls the speed comparison misleading, since Jev only returns structured output, and disputes the cannot-hallucinate claim because a valid type can still hold a wrong value. Others note ordinary LLMs can already be forced into structured output.

DSPy: programming, not prompting, language models

Declares typed input/output Signatures for LLM modules and optimizes the underlying prompts and weights against a metric. Its Signature abstraction is the closest widely-used open equivalent of Jev's typed-question interface. Star count is GitHub's rounded display figure.

decider: one-pass typed decisions with calibrated probabilities (Qwen3.5-2B)

Open reproduction of the System One model class, fine-tuned from Qwen3.5-2B-Base, returning a probability distribution per typed question in a single forward pass. Serves TypeSafe's POST /v1/systemone wire format so TypeSafe SDKs work unchanged by repointing TYPESAFE_BASE_URL.
