Questions about this entry
Short answers drawn from the linked project or page.
The page presents Jev as flight director with live judgments listed newest first and bars for its option probabilities, so decisions are model-driven at least in part. There is no public repo linked from the catalog entry, so the split between scripted scenes and model calls cannot be audited from the page alone.
Undocumented. The captured page shows a Kennedy Space Center preflight console, time warp at 1x through 100x, and four mission stages from launch to arrival window, but mentions no key, no pricing, and no count of calls per run. Budget by measurement, not by the visuals.
The page tracks altitude, velocity, fuel, distance to the Moon, and elapsed time, and starts with the director waiting for a first decision. Whether a wrong call is blocked, merely displayed, or ends the run is not documented, so treat the mission as a demonstration rather than a game with real stakes.
The entry copy notes Cloudflare may interpose a bot check before the app loads. If the page stalls on a check, that says nothing about the demo itself; also note there is no public repo linked from the entry, so there is nothing to inspect or run locally.
Jev pilots from liftoff through staging, cruise and orbital capture, and every choice it makes commands spacecraft attitude or a flight maneuver rather than just narrating.
They show the option probabilities Jev assigns to each candidate decision, listed newest first, so you can see how confident the flight director was about a choice.
Yes. The interface offers time warp at 1x, 10x, 20x and 100x, along with a next-mission-event control, and the flight path only appears after liftoff.

Two runnable demo apps that send identical typed questions to OpenAI Decisions (gpt-6-luna) and TypeSafe Jev (jev-latest) in parallel: a support ticket router over 20 labelled tickets and a cloud alert triage over 15 labelled alerts, with thresholds in plain Python making the final calls.
