TypeSafe Jev API

Jev is TypeSafe’s System One model. It does not generate text: you send content and typed questions, and get answers with probabilities (and confidence where applicable). Programs can branch on those scores without parsing prose.

Action	Method	Path
System One (TypeSafe official)	`POST`	`/typesafe/v1/systemone`
Decisions (OpenAI-compatible)	`POST`	`/v1/decisions`

Host: https://api.omniall.ai · Auth Authorization: Bearer sk-...
Models: jev-1.14.0 · jev-preview · jev-latest Full schemas and playground: API Reference → Chat → TypeSafe / Jev.

Question types

TypeSafe	OpenAI Decisions	Returns
`noul`	`predicate`	P(yes) in `[0, 1]`
`choice`	`choice`	Top option + per-option probabilities + confidence
`score`	`score`	Weighted score + per-level probabilities + confidence

One request can mix types. Extra questions do not change other answers — each question is independent over the same content.

Quick start (TypeSafe official)

curl -X POST 'https://api.omniall.ai/typesafe/v1/systemone' \
  -H 'Authorization: Bearer sk-...' \
  -H 'Content-Type: application/json' \
  -d '{
    "state": "Help! My payouts have been failing for 3 days.",
    "model": "jev-1.14.0",
    "questions": {
      "department": {
        "type": "choice",
        "instructions": "Which team should handle this?",
        "criteria": {
          "billing": "Payments, invoicing, refunds",
          "technical": "Bugs, outages, integrations",
          "sales": "Pricing, upgrades, new accounts"
        }
      },
      "is_urgent": {
        "type": "noul",
        "instructions": "Does this convey urgency?"
      }
    }
  }'

TypeSafe SDK: set base_url to https://api.omniall.ai/typesafe (key = your Omniall API key).

Quick start (OpenAI Decisions)

curl -X POST 'https://api.omniall.ai/v1/decisions' \
  -H 'Authorization: Bearer sk-...' \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "jev-1.14.0",
    "input": "I was charged twice for my order.",
    "questions": [
      {
        "type": "predicate",
        "name": "refund_requested",
        "instructions": "Is the customer asking for money back?"
      }
    ]
  }'

OpenAI SDK (openai Python ≥ 3.26 / JS ≥ 7.30): base_url=https://api.omniall.ai/v1, then client.decisions.create(...).

When to use it

Ticket / form routing (team or next action)
Priority and risk scoring
Moderation / output checks (compliance, grounded citations)
Agent control (which tool to call, whether to escalate)

Use probability and confidence thresholds: high confidence → automate; low → human review.

Limits & tips

Default context: 64k tokens; state/input + longest question ≤ 32k. Optional header TypeSafe-Danger-Zone-Long-Context: true raises both to 262k (preview; slower / less accurate).
Images: TypeSafe official needs TypeSafe-Danger-Zone-Images: true + assets; Decisions can send input_image (auto-enables images). PNG/JPEG only; 256–1568 px per side; ≤ 16 MiB each.
English works best; other languages are usable but less accurate — validate on your data.
Probabilities are rounded to two decimals; sums may be 0.99 instead of 1.0 — no need to renormalize.

Admin channel setup: create a TypeSafe channel (type 68), Base URL https://api.ephone.ai (or your upstream), and enable jev-* models for the user group.
