Ads failure modes 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 failure modes slice of the ads creative and policy decisions pack. Intent: apply the Jev (TypeSafe System One) decision model to ads creative and policy decisions failure modes. Primary search language: Ads Jev failure modes. 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
Ads creative and policy decisions breaks in product-specific ways. This page lists those modes so you can write tests — not a generic “AI can be wrong” essay, and not a rival limitations-page clone.
Hub: Use cases. Compare, when the other tool is the real job: ad bidding systems.
Failure Modes inputs
Many failures start as contract violations (distractors, missing ad creative + claim text). Canonical shape:
{
"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." }
}Decision signals and actions
- Bidding systems optimize auctions; they do not read your legal excerpts (compare).
- Jev will not compute ROAS or bid.
- A low policy Noul is not a lawyer’s sign-off.
- Platform rejection after you “allowed” — still possible.
- Invented CTR lifts from using Jev.
HTTP vs application:
| You see | Class | Ads move |
|---|---|---|
| 401 / 422 / 429 / 529 | Documented HTTP | Fix key/body or back off — errors |
| 200 + flat confidence or Noul ≈ 0.5 | Low confidence | Hold; do not launch spend against a live campaign |
| Empty gather | Missing evidence | Skip Jev or ask “is enough information present?” |
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
Fail closed: do not launch spend against a live campaign. Schema-safe answers are not factual correctness. 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
Your canary set should include each bullet above.
- False-allow on a banned-claim canary set
- False-hold rate (creative throughput)
- Agreement after policy-text edits
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.
Official Python and JavaScript SDKs read TYPESAFE_API_KEY and retry documented 429/529. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.

FAQ
If the API returns 200, is the decision good? 200 only means the call parsed. Low confidence, Noul ≈ 0.5, or a policy miss are application failures.
Where do official weaknesses live? TypeSafe’s jev-1.13 jaggedness note — distractors, arithmetic, adversarial content. We do not invent more.
Where is the rest of the Ads pack? Start with Ads evaluation and Ads decision workflow. 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.
What this page does not claim
- Not an ads manager or bidding engine.
- No performance numbers.
- Not official TypeSafe.
- Official TypeSafe status, or that jev.pro issues API keys.
- That a schema-constrained answer is automatically factually correct.
