Jev API Versioning

There are two version axes. The path is /v1/systemone and /v1/models. The model field selects weights: jev-1.13.0 vs aliases jev-latest / jev-preview (both pointed at jev-1.13.0 on the models page we read). Aliases move when TypeSafe ships.

This site does not sell, issue, or proxy TypeSafe keys. Authenticate with a credential you already have from the console or a documented gateway.

Jev API Versioning: context

The response model field reports the versioned id that answered. Log it. GET /v1/models currently lists aliases; versioned ids still work on POST.

Jev API Versioning: inputs

Send a real name from the models page. Do not invent jev-1.13 if only jev-1.13.0 is documented.

Jev API Versioning: decision logic

Production gates should pin. Upgrade in a diff after you retune. Preview aliases are for exploration.

Jev API Versioning: implementation notes

Path v1 changing would be a TypeSafe announcement. We will not guess v2. Confirm models.

FAQ

What is the evaluation URL?

According to TypeSafe documentation: POST https://api.typesafe.ai/v1/systemone.

What is the difference between jev-1.13 and jev-1.13.0?

TypeSafe’s models page uses jev-1.13 as the product line and jev-1.13.0 as the versioned id. Aliases are jev-latest and jev-preview. Do not send a truncated id unless that page lists it.

Are prices and rate limits on this page ours?

No. They are vendor-published list figures. Confirm on docs.typesafe.ai/models. Limits can change without notice.

What this page does not claim

• Official TypeSafe status, logos, or support.
• That jev.pro sells, issues, or proxies API keys.
• Extra first-party HTTP routes beyond POST /v1/systemone and GET /v1/models unless the API reference lists them.
• Invented latency SLOs, search volume, or unofficial prices. List price and rate limits are vendor claims — confirm on models.
• That a schema-constrained answer is automatically factually correct.
