Jev for security engineering
Kostas on threat hunting with Jev: define the questions and outputs, then rank, score and classify activity at scale.
Open x.com ↗This made me rethink where AI actually fits into security engineering.
For purely engineering work, forget about ChatGPT or Claude.
TypeSafe AI just released Jev, and I think it’s going to change how we build AI into security workflows.
Instead of asking an LLM to “investigate
How builders describe it
An argument that security work is full of bounded engineering decisions that belong to Jev rather than a chat model, with examples of the calls that fit.
