How we select a case

We look for a concrete use of a typed decision: a specific input, a choice the model makes, and something the surrounding software does with the answer. We group examples by the task they demonstrate, rather than their social engagement.

The initial selection was discovered through Hiwoniu's Jev Case collection, an index of public posts on X. We thank its creator for the discovery work. Our case titles, explanations, workflows and cautions are original editorial writing. Metadata and media references are adapted from the open-source collection; its MIT notice is retained in our project.

How we curate tools

The tool directory brings together community projects and official TypeSafe AI SDKs. Each listing links to its primary source, identifies its creator and explains the setup it requires. We check project descriptions against their repositories or official documentation. “Open source” and “public source” are distinct labels; a public repository alone does not establish an open-source license.

Source review means reading the linked material, not installing, auditing or benchmarking a tool. These projects run outside this site. Their authors maintain the code and documentation, and their own accounts or API keys may be needed.

Credit stays with the creator

Each case names the original creator and links to the original post. Videos are third-party previews supplied by the reference collection; rights remain with their creators and platforms. External media may change or become unavailable, so the original-post link remains available as a fallback.

What “reviewed” means

For guides, it means we checked the cited official documentation on the stated date. For community cases, it means we reviewed the indexed source description and wrote the accompanying interpretation. It does not mean we ran the project, verified a speed claim or audited the code.

Code examples in the guides illustrate documented request patterns. This content-only site does not send requests to Jev and does not offer an API playground. A creator's reported benchmark remains their report, not a result from this publication.

Editorial principles

  • Link to the original work and distinguish it from our interpretation.
  • Describe useful patterns without turning a demo into a universal claim.
  • Keep model versions and review dates visible when they affect the explanation.
  • Make uncertainty and failure cases part of the story.
