๐Ÿง  JEV ยท System One

Typed Decisions, Calibrated Probabilities

TypeSafe's Jev โ€” the first System One model. Returns typed answers with probabilities and confidence. Cannot hallucinate. 70-500ms. $0.042/MTok input, output free.

๐ŸŽฏ Endpoints

JEV cannot emit values outside your schema. Each call returns probability distributions you can threshold and route with. Adding more questions to a call barely changes latency.

โš™๏ธ Decompose an Agent Function

Pass a function name + description. JEV identifies the dominant Quilt opcode (BIND/LINK/EFFECT/VIEW/TICK/FORGET/PROOF/ROUTE/CRDT/WORLD/TIME) + complexity + decomposability + inter-quilt scope.

๐Ÿ“š Preset agents to try

routeUserRequest
Looks up a user by ID and returns their profile
mergeTwoNotebooks
Merges two CRDT notebooks in real time
scheduleRecurringJob
Schedules a cron-style job that fires every hour
removeOldCells
Sweeps cells older than 30 days
verifyWitnessChain
Validates the HMAC chain on the witness log

๐Ÿšฆ Route a Request

Pass any request text. JEV picks the best handler: fast-decision (JEV itself) / cheap-generative / deep-reasoning / image / voice / human.

๐Ÿ“š Preset requests to try
