How does Inbox Zero use Jev?

Its decision-model module asks typed questions through openrouter:typesafe/jev-1.13 for tasks such as choosing which rule matches an email, cold-email detection, thread status, recurring patterns, unsubscribe-page classification, and sender categorization.

What happens if the Jev decision call fails?

The decision step falls back to the configured LLM for that step. Multi-rule selection is unsupported on the decision-model path and uses the LLM path, so a failure never blocks email processing.

Is the Jev decision layer on by default?

No. The default decision model is openrouter:typesafe/jev-1.13, but it is enabled per deployment with DEFAULT_DECISION_MODEL_ENABLED, and users who bring their own AI key are not enrolled by default.

What thresholds does Inbox Zero use?

choose-rule.ts sets MIN_CHOICE_CONFIDENCE to 0.3 and COLD_EMAIL_THRESHOLD to 0.7, so low-confidence rule choices and cold-email scores are handled by those gates.

Which provider keys does the decision layer need?

Direct TypeSafe access uses TYPESAFE_API_KEY; other providers resolve their own keys through OpenRouter, Vercel AI Gateway, or OpenAI. Self-hosted deployments need provider keys of their own.

Does Inbox Zero test its decision modules?

Yes. Each module has eval tests under apps/web/__tests__/eval/decision-model, covering choose-rule, cold-email, thread-status, recurring-pattern, unsubscribe-page, and categorize-sender.

What license does Inbox Zero ship under?

GitHub reports the license as NOASSERTION, so check the repository LICENSE for the actual terms before relying on it commercially.

Highlights

The default decision model is openrouter:typesafe/jev-1.13, enabled per deployment via DEFAULT_DECISION_MODEL and DEFAULT_DECISION_MODEL_ENABLED.
Modules under apps/web/utils/decision-model cover choose-rule, cold-email, thread-status, recurring-pattern, unsubscribe-page, and categorize-sender.
Each module has eval tests under apps/web/__tests__/eval/decision-model; choose-rule.ts sets MIN_CHOICE_CONFIDENCE 0.3 and COLD_EMAIL_THRESHOLD 0.7.
Direct TypeSafe access uses TYPESAFE_API_KEY; other providers resolve their own keys through OpenRouter, Vercel AI Gateway, or OpenAI.
If a decision call fails, that step falls back to the configured LLM, and multi-rule selection stays on the LLM path.

Watch out

GitHub reports the license as NOASSERTION (check the repository LICENSE for terms); self-hosted deployments need provider keys, and users who bring their own AI key are not enrolled in the decision model by default.
