Jev's Wikiracing demo returns typed link choices at every hop
Jev's Wikiracing demo shows each hop returning a typed, probabilistic choice from the page's existing links, avoiding hallucinated dead links, which the author sees as a cheap reliable branch for tool routing and guardrails.
the best model to come out this week is one that cannot write meet Jev they had a nice Wikiracing demo in the release paper. it's a game where you start on one Wikipedia page and try to reach another by only clicking links that already exist on the page. each hop: hundreds to thousands of Wikipedia links. pick one. do not invent a URL. repeat. - LLMs write a link and sometimes hallucinate a dead end (the error compounds) - Jev takes the current state, looks at the options you already defined, and returns a typed choice with probabilities. and the results speak for themselves zoom out and you can feel why this might be a paradigm shift in how we use models. A lot of software needs a reliable fork: which tool, which API, which row, which next action. If that fork gets cheap, typed, and fast, you do not run one careful agent, you spray decisions into the hot path. same shape as Wikiracing, applied to tool routing and guardrails
