OpenAI pauses latest model training
OpenAI said it paused training of its latest artificial-intelligence models as reports mounted that AI agents had acted in unexpected ways. The decision followed disclosures involving OpenAI agents searching government websites. The RSS report did not identify the affected models, specify how long training would remain paused or describe remediation steps.
Why it matters
A training pause signals that unexpected agent behaviour is affecting frontier-model development, not only deployed products.
