THE UNNECESSARY PART
The Jev lab.
What happens when you ask an AI to do arithmetic? API guides, a very odd npm package, and the actual benchmarks.
12 guides
What is Jev? Typed AI decisions, explained
An independent introduction to TypeSafe’s Jev model, typed questions, and the deliberately impractical is-jodd example.
Jev API quickstart with JavaScript fetch
Build a small Jev request with native fetch, inspect a Noul answer, and keep credentials on the server.
Jev Noul questions: turn a probability into a boolean
Understand a Jev Noul result, validate its shape, and make the boolean threshold explicit in your code.
Jev Choice vs Noul: pick the answer shape your code needs
Compare categorical Choice answers with Noul yes/no judgments using is-jeven and is-jodd as a concrete example.
Getting started with is-jodd: API, requirements, and the joke
Read the is-jodd contract before using it: Node 24+, API credentials, safe integers, async results, and its custom restrictive license.
is-jodd vs is-jeven: smaller runtime, no proven speed win
Compare the actual is-jodd 1.0.0 and is-jeven 1.0.0 interfaces, package sizes, and live benchmark results.
Jev parity benchmarks: what our 44 requests actually showed
Read the full context behind is-jodd’s live benchmark: paired inputs, warmups, accuracy checks, uncertainty, and the separate transport pilot.
Jev confidence vs correctness: what a strong answer proves
Separate Jev’s reported uncertainty, your decision threshold, and correctness measured against known answers.
Jev API errors and timeouts: keep failures separate from false
Handle missing credentials, HTTP failures, cancellation, and invalid Jev answers without turning them into ordinary parity results.
Await before negating: the is-jeven Promise trap
Why !isEven(n) is not an oddness check, and how to negate an async boolean without hiding errors.
Smaller Jev requests: what saved 51 JSON bytes
Examine is-jodd’s compact state and Noul question, then distinguish request bytes, module size, archive size, and live latency.
When not to use AI for math: the is-jodd example
Use exact arithmetic for exact questions, and keep probabilistic interpretation outside the calculation itself.
