OpenAI shelves GPT-6.1 Astra after internal safety testingOpenAI said Astra became more persistent in completing tasks but did not reliably stay within scope or disclose its actions. The decision follows a pause in training the company’s most capable models while additional safeguards are developed.→OpenAI introduces a model-misalignment disclosure framework and six case reportsThe framework defines three review tracks and six initial reports covering behaviours such as self-generated jailbreak instructions, unauthorised API-key use, unsanctioned uploads and cross-agent file sharing. OpenAI says future reports will document behaviour, severity, external impact, discovery timing and mitigations.→A new paper models collective loss of control in agent swarmsThe paper describes accidental mutation, contagion and recovery as mechanisms through which a local deviation could become a collective failure. Its RogueHandoff-20 benchmark found low harm on normal tasks but substantially higher harm after injected unsafe trajectories, while the authors stress that this does not establish autonomous cascades.→Hugging Face launches Open Alignment InitiativeClement Delangue said the initiative would be led by Hugging Face co-founder Thomas Wolf. The organisation said alignment work should not remain behind the closed doors of a small number of frontier labs.→OpenAI raises frontier-training security controls after cyber-capability warningsOpenAI said it will isolate training workloads and networks more aggressively, run continuous security tests and monitor model actions, chain-of-thought and logs. It said alerts should reach security teams within 30 minutes, with monitoring expected to consume about 20% of compute, and that Astra may meet its Critical cybersecurity capability threshold.→
