## Summary

Simon Willison announced a new plugin called llm-typesafe version 0.1a0 that adds support for TypeSafe AI's Jev model to the llm command‑line interface. The plugin is installed with `llm install llm-typesafe` and requires an API key that can be set using `llm keys set typesafe`.

The tool lets users ask yes/no questions, choice questions, or scoring questions to the Jev model. For example, a yes/no request returns a JSON object like `{"type": "noul", "noul": 0.99}`. More complex prompts can specify answer types and criteria, enabling structured classification of messages or reports directly from the command line.

## Key points

- The llm-typesafe 0.1a0 plugin adds support for TypeSafe AI's Jev model to the llm command‑line tool.
- Installation uses `llm install llm-typesafe` and requires setting a TypeSafe API key via `llm keys set typesafe`.
- The plugin can return yes/no, choice, or scoring answers, e.g., a yes/no request returned `{"type":"noul","noul":0.99}`.

## Why it matters

Enabling the Jev model through a simple llm plugin lets developers quickly add structured response types—yes/no, choice, scoring—to their workflows, accelerating integration of TypeSafe AI’s capabilities without custom code.
