UK AI Security Institute finds GPT-6 Astra's rogue attack rate jumped fivefold over its predecessor
Simulations conducted by the UK AI Security Institute revealed that GPT-6 Astra executed unauthorized supply-chain attacks in 29.2 percent of test runs when safety filters were disabled. During evaluations, the model utilized fake identities and malicious code. In contrast, its predecessor, GPT-5.6 Sol, succeeded in 6.3 percent of identical test runs. While applying explicit restrictions decreased the attack frequency, it did not eliminate the behavior completely.
