PLAYGROUND SAFETY LIMITS

Steady requests. Visible limits.

0 active · 0/20 queued

Browser: one start every 1.2 seconds (at most 50/minute), up to 2 active calls and 20 waiting. Shared by examples in this tab. Waiting requests cancel when their run is stopped; a full queue rejects new work without an API call.

Server: 60 requests per rolling 60 seconds and 2 concurrent calls per key, per server instance. Other tabs using the same key share that instance’s allowance. This in-memory safeguard resets on restart and is not a distributed or account-wide quota.

Source: playground policy in lib/requestRateLimit.ts. TypeSafe may impose separate limits. Provider HTTP 429 pauses calls until its reported reset; without a reset time, retry requires your action. HTTP 402 is a budget/billing failure, not a pacing limit. No automatic retries or background replay.

REASONING / 12 QUESTIONS

Jev takes an IQ-style test

Number sequences, logical deductions, and symbol patterns. Give Jev the questions, then check every choice against the answer key.

WORKSPACE GUIDE

IQ-style test

Give Jev 12 original reasoning puzzles and check each choice against an explained answer key.

Reasoning puzzleJev choiceChecked answer

What you provide

Twelve fixed, original multiple-choice questions: four numerical, four logical, and four text-based patterns. Each states its assumptions.

What happens

Live Jev receives one isolated question and four choices per call. The reference key and explanations stay local. Code checks the answer and grades it against the key; a provider error or malformed answer stops the run.

What you get

A question view that follows the run, with a two-second reading pause after every answer. The final report shows an estimated IQ, raw score and category breakdowns. The IQ number uses a disclosed, uncalibrated formula; incomplete tests get no estimate. Exports include the scoring assumptions and method version, alongside local-demo or live execution.

Walk through a run

  1. 01

    Choose a run

    Local demo always selects A without a model call. Live Jev uses your configured key for up to 12 questions.

  2. 02

    Watch each answer

    The view follows Jev and holds each answer for two seconds. Inspect earlier questions at any time, then enable Follow current question to rejoin the run.

  3. 03

    Read the final breakdown

    A completed test opens a numerical IQ estimate, raw score and category breakdowns. The estimate is an uncalibrated heuristic with a disclosed formula. Errors stop the run and leave it incomplete, without an estimate.

Try this

Run the local demo, which always chooses A, then explicitly select Live Jev to compare on the same questions. A raw score on this practice set is not an IQ or a general capability benchmark.

Execution limits

The IQ estimate uses assumed reference values, not human norms. Confidence does not prove correctness. Reference answers are withheld from Jev; patterns are sent as text.

Ready · Local demo

The local demo always picks A. It shows how scoring works and makes no model calls.

Not a standardized IQ score. The numerical estimate uses assumed reference values; these original practice puzzles have no human population norms. Patterns are sent as text, not images.

Uniform random guessing would average 3 / 12 across repeated full tests. This is an expected value, not a measured run.

Growing gaps

What comes next? 6, 11, 18, 27, ?

Assumption Each successive gap is 2 larger than the previous gap.

No scored answer yet

Confidence describes the model’s response. The checked answer determines correctness.

B · 38

The gaps are 5, 7, 9, then 11. Adding 11 to 27 gives 38.
