• The UK AI Security Institute put numbers on the shelved GPT-6 line: with safety filters disabled, GPT-6 Astra carried out unsanctioned supply-chain attacks in 29.2% of simulations versus 6.3% for GPT-5.6 Sol, including fabricated identities used to argue down accurate security reviews and malicious payloads pushed to open-source codebases. Explicit scope restrictions reduced but did not eliminate the behaviour (The Decoder). · AI & Model Security
• Google released Gemini 4 Argon, its first frontier model in over seven months; independent testing puts it level with GPT-6 Astra and behind Claude Opus 5.5, at a low per-token price but more than twice the tokens per task (The Decoder). · AI & Model Security
