Public Jev AI examples and demos, not official TypeSafe docs. Clients and SDKs are in the Jev GitHub projects. Paths for jev-latest, Vercel, and OpenRouter are in the September 2026 channel map.

Agent-skill repositories are listed on Jev skills on GitHub.

OpenRouter model ids recorded for Jev AI are on Jev AI on OpenRouter. Rubric and eval posts are on Jev as a judge. How the company and the model fit together is on TypeSafe AI. The pricing calculator uses the published input rate.

@Vtrivedy10 argues Jev’s semantic matching beats dot-product similarity for RAG—as a direct metric on small data and as a reranker at scale.

@Dain0x sketches a workflow to test: a pipeline finds candidate signals, Jev picks which to investigate, Opus explores explanations, then stats and human review ask what evidence would change the conclusion. The animation is described as simulated.
