The decisions Jev makes

In a single call, Jev evaluates each of these — in parallel, against the same input:

noulallow

Is this comment safe to publish automatically without human review?

returns a calibrated yes/no probability.

scoretoxicity

How toxic or hostile is the language?

rates it on an ordered scale:

  1. friendly / neutral
  2. mildly rude
  3. clearly insulting
  4. hateful or harassing
choicecategory

Which policy area is most relevant?

picks one of these options:

  • clean — no policy concern
  • harassment — insults or harassment toward people
  • spam — spam or advertising
  • selfharm — self-harm or violence

The exact request

This is the real payload behind the live demo — copy it, change the state, and you're building:

{
  "model": "jev-latest",
  "state": "User comment on a public forum: \"honestly this whole community is trash and the mods are clowns, but the tutorial itself was actually really helpful, thanks for posting\"",
  "questions": {
    "allow": {
      "type": "noul",
      "instructions": "Is this comment safe to publish automatically without human review?"
    },
    "toxicity": {
      "type": "score",
      "instructions": "How toxic or hostile is the language?",
      "criteria": [
        "friendly / neutral",
        "mildly rude",
        "clearly insulting",
        "hateful or harassing"
      ]
    },
    "category": {
      "type": "choice",
      "instructions": "Which policy area is most relevant?",
      "criteria": {
        "clean": "no policy concern",
        "harassment": "insults or harassment toward people",
        "spam": "spam or advertising",
        "selfharm": "self-harm or violence"
      }
    }
  }
}

Wire it into your code

Read the typed answers and branch in plain code — no parsing. Auto-handle the high-confidence cases and route the uncertain ones to a bigger model or a human. It's one API call and output is free, so ask every question you need at once.

Build your own

Every scenario above is a single API call. Try any of them free in the playground, then get a hosted key to ship it in minutes.
