Jev versus text-generating models
Jev does not generate free-form text. A side-by-side video compares parallel decision-making with token-by-token text generation.

Explains that Jev receives a tool's approval policy, description, and invoked params at inference time and returns a verdict; approved calls start immediately while denied calls run after codegen like normal PTC.
The approval policy is a prompt. Jev is provided the tool's approval policy, along with its tool description and invoked params at inference-time and returns a verdict. Approved calls start immediately and denied calls run once the codegen is complete just like normal PTC.
