Jev operating model
An operating model for Jev is how a team ships typed decisions without turning Playground into production. It is not TypeSafe’s org chart and not a consulting framework. Independent. docs.typesafe.ai.
Independent angle (cover, do not clone)
Win delta: RACI on questions/floors/traces plus a weekly operate cadence. We do not clone a rival “build with System One” narrative or a Gartner operating-model page.
Question and context
System One answers are cheap to call and expensive to govern if nobody owns criteria edits. Official agent-skill / how-to guidance: humans edit criteria. Make that a required reviewer, not a suggestion.
Core concepts
| Workstream | Owns | Does not own |
|---|---|---|
| Question pack | Product + a named reviewer | Live-edit in an undocumented console |
| Floors / τ | Risk or ops with eval evidence | Copy-pasting 0.9 from a blog |
| Door + pin | Platform | Mixing marketplace ids silently |
| Traces + gold | Data / platform | Hoping TypeSafe stores your labels |
| Irreversible actions | App owners | “The model said so” |
Cadence:
- PR on
instructions/criteria/ floors (same as application code). - Staging replay of gold on the pinned id.
- Prod promote the triple (sha, pin, door).
- Weekly sample of handoffs → gold (feedback guide).
- Abort on alias drift, 422 spike, or criteria hotfix without replay.
Practical approach
Write the fail-closed default before the happy path: if POST /v1/systemone 529s, what does the user see? If you cannot answer, you do not have an operating model — you have a demo.
Link roles on team roles and metrics on success metrics. Checklists: design, implementation, launch.
Risks and trade-offs
A heavy RACI on a three-person startup is parody. Keep the minimum: one human for criteria, one pin, one gold file, one abort owner. Enterprises that skip change control will still have SoD theater — just not for the model that routes money.
Vendor rate limits (models page) can change; do not treat a blog reprint as a contract.

FAQ
Does TypeSafe host our operating model? No. You run questions, traces, and floors. They host the model.
Can product edit criteria in production? Only if that edit is a reviewed release. Live-tweaking floors is how silent false-allows ship.
Where is the weekly loop written down? Playbook and best practices.
