Open-source decision models Clef and Kev have been released to help agents programmatically gather context, make decisions, and take actions. Clef is fully Jev-API compatible and available under an Apache 2.0 license, while Kev offers a family of four models ranging from 0.8B to 27B parameters.

  • Clef and Clef-flash return typed answers with probabilities for agent decision-making.
  • Kev uses the same API as TypeSafe's Jev, allowing applications to switch endpoints easily.
  • pplx-decider-v1-27b is a new decision model fine-tuned from Qwen3.8-27B that competes with Jev benchmarks.

OpenAI dismissed three safety researchers for sharing confidential information with a third-party AI safety group, according to the WSJ. This follows reports of executives ignoring safety warnings and coincides with security issues involving AI agents.
