The Verge 2 weeks ago 28 ● 16 sources
David Robinson resigned from his OpenAI safety role and published an editorial warning that the industry’s culture is broken. This week, he quit and is now publicly sounding the alarm about model-safety practices going beyond adding rules or regulations. The result is added pressure on AI safety efforts and scrutiny of how OpenAI and the broader industry handle training and release safety reports.
Decision AI Models Explained: TypeSafe Jev vs Fastino GLiDE, GLiNER2.5-Decide and Open-Source Competitors

The shift is toward low-latency, confidence-calibrated model outputs for routing, triage, reranking, and evaluation pipelines while reserving LLMs for open-ended writing and reasoning.
