Ads input contracts with Jev
Launching spend is irreversible. Jev judges creative copy and claims against your brand/legal excerpts. Bidding, budgets, and auction math stay in the ad platform.
This unofficial page is the input contracts slice of the ads creative and policy decisions pack. Intent: apply the Jev (TypeSafe System One) decision model to ads creative and policy decisions input contracts. Primary search language: Ads Jev input contracts. Confirm patterns on docs.typesafe.ai. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.
Independent angle (cover ≠ clone): Policy/compliance gates + spend irreversibility — not a clone of bidding-system IA or a rival ads recipe slug.
Ads use-case context
An input contract is the allow-list of fields you will ever POST for ads creative and policy decisions. It is a decision contract for the ad creative + claim: if a field is not named in instructions, it should not be in state. That is how you beat noisy “dump the object” integrations — the rival-intent failure mode — without cloning anyone’s IA.
Hub: Use cases. Compare, when the other tool is the real job: ad bidding systems.
Input Contracts inputs
Documented System One inputs: state (string, object, or array of text) and a questions map. English is the primary training language. Images, audio, and video are not accepted.
Allow for ads creative and policy decisions:
{
"creative": { "id": "ad-441", "headline": "Lose 10kg this week", "body": "Guaranteed results." },
"landing": { "claim": "Results vary; no guarantee." },
"policy": { "health": "No absolute health outcome claims.", "superlatives": "No unsubstantiated #1 claims." }
}Bind paths: creative.headline, creative.body, policy.health, landing.claim.
Refuse at the wrapper (do not send):
- bid curves, CPA targets, audience graphs
- the full landing-page HTML
- competitor ads as a dump unless you ask a comparison Noul
TypeSafe’s published list price for jev-1.13 is $0.042 per million input tokens (vendor claim — confirm on the models page); output tokens are free on that same page. Unused distractors still bill as input.
Decision signals and actions
The contract exists so each primitive stays atomic:
| Id | Type | Job |
|---|---|---|
policy_ok |
Noul | Does creative violate policy.* given landing.claim? |
claim_type |
Choice | performance / health / pricing / social_proof / other |
brand_risk |
Score | how embarrassing if this ships |
If a new CRM field appears, either add a question that names it or drop it. Do not “just include it.” Do not treat a Noul of 0.5 as a “medium” ads creative and policy decisions score — it means yes and no are equally likely. Conjunctions stay in your code.
Guardrails and escalation
Contracts are a guardrail: missing required text → do not call Jev (or ask a Noul “is enough information present?”). That is cheaper than a confident wrong policy_ok. TypeSafe’s confidence-gated examples use a lower bar for recoverable reads than for irreversible actions. Those numbers are illustrations. For ads creative and policy decisions, treat allow_launch as the high bar (spending against a live campaign). Tune on labels — see offline evaluation.
Evaluation and rollout notes
Version the contract (field list + criteria git SHA) next to the pinned model. Replay hold / allow gold from brand+legal, plus claim_type gold when either changes. Pin jev-1.13.0 (the versioned id) after you fit thresholds. jev-latest and the marketing line jev-1.13 can move. Log the response model. TypeSafe’s published list price for jev-1.13 is $0.042 per million input tokens (vendor claim — confirm on the models page); output tokens are free on that same page. Unused distractors still bill as input.

FAQ
What happens if I send the whole warehouse row?
jev-1.13 loses accuracy as distractors grow (official jaggedness note). Drop bid curves, CPA targets, audience graphs. TypeSafe’s published list price for jev-1.13 is $0.042 per million input tokens (vendor claim — confirm on the models page); output tokens are free on that same page. Unused distractors still bill as input.
Can I send images of the artifact? No. State is text (string, object, or array of text). Transcribe first.
Where is the rest of the Ads pack? Start with Ads decision workflow and Ads evidence collection. Cluster hub: Use cases.
Will Jev pause campaigns when CPA spikes? No. That is the ad platform / your rules. Jev judges language and policy fit.
Can we send images of the creative? Not to System One. Transcribe or paste the copy. Images are not accepted.

- Not an ads manager or bidding engine.
