About this site
Jev Model Guide (typesafe-jev.com) is a third-party learning site maintained by the independent community. It has no affiliation with, endorsement by, or agency for TypeSafe AI; Jev, System One, TypeSafe, and related names belong to their owner. Opinions here are the editors’ own.
Maintainer and corrections
Section titled “Maintainer and corrections”The site is maintained by the owner of the public onlyoasis/awesome-jev-cases repository. The maintainer edits this guide and checks its examples; automated discovery provides candidates for the directory. Repository stars, licences and source dates are snapshots, not quality certifications. No TypeSafe endorsement is implied.
For corrections, contact contact@typesafe-jev.com with the page, disputed statement and original link, or open an issue on the public catalogue for catalogue corrections. Do not send API keys or private tickets. The triage, routing, moderation and tool approval labs publish synthetic samples, code and recorded API outputs. Replay is labelled separately from fresh live calls; small samples do not establish production accuracy. This tutorial batch was checked on 2026-10-11; each older source keeps its own verification date.
How we separate fact from noise
Section titled “How we separate fact from noise”Every page ends with a “Sources & verification” list; each source carries a type badge and a verification date. The taxonomy:
| Badge | Definition | Examples |
|---|---|---|
| Official | TypeSafe’s own domains, repos, announcements | docs.typesafe.ai, the typesafe-ai org |
| Press | Media reports relaying claims | TechCrunch, 36kr coverage |
| Community | Community projects and posts, as self-described | GitHub community repos, YouTube videos |
| Research snapshot | Independent research snapshots we cite | Archived copies of official pages |
| This site | Our editors’ synthesis and advice | Threshold suggestions, checklists |
In body text, statements that can’t carry an inline citation are marked official / media / community / this site’s advice in words.
Verification method (executed 2026-09-22)
Section titled “Verification method (executed 2026-09-22)”- Official facts: fetched the then-current docs.typesafe.ai pages and official blog directly; key numbers (pricing, limits, type parameters) follow the current official docs
- GitHub projects: verified existence, ownership, license, and a stars snapshot per repo via the GitHub API (see Ecosystem)
- Videos: verified every title and channel via the YouTube oembed API; unverifiable publish dates are marked unknown (see Video tutorials)
- Unverifiable figures: explicitly marked “not verified” — or left out entirely (see the disputes table in Limitations)
What we don’t do
Section titled “What we don’t do”- Present community implementations as TypeSafe official projects
- Describe open replicas as Jev going open-source
- Republish unverifiable benchmark tables (unless clearly labeled third-party)
- Embed third-party video players; analytics and ads follow build configuration and preferences (see privacy)
- Display or store API keys; site examples read from environment variables only
Content & languages
Section titled “Content & languages”The site ships in English and 中文; semantic pairs share one translationKey and stay technically consistent, with the Chinese edition as the primary. Spotted a translation or factual error? Email contact@typesafe-jev.com.
