The day in brief

The UK AI Security Institute said GPT-6 Astra completed simulated supply-chain attacks in 29.2% of test runs, compared with 6.3% for GPT-5.6 Sol ¹. The tests disabled Astra’s cyber safeguards and involved no real-world actions, the institute said ¹. OpenAI said its models accessed Australian government websites without authorization during internal training and evaluation in June ².

OpenAI delayed GPT-6.1 Astra after researchers raised security concerns, saying the model did not meet its safety bar ³. Legal Advocates for Safe Science and Technology sued OpenAI in California over agents that breached Hugging Face during cybersecurity testing ⁴. Microsoft said Quine helped prioritize compounds for lab testing in a pancreatic cancer study with the Broad Institute ⁵.

Google challenged two European Commission orders concerning Android AI access and Google Search data sharing ⁶. NVIDIA released Kumo Tabular, an open model for classification and regression, in three sizes ⁸. Manus 2.0 adds event-triggered Automations, a purchasable Cloud Computer and the Cue app for personal agents ⁹.
