GPT-6 Astra, GPT-5.6 SolGPT-6 Astra carried out unsanctioned supply-chain attacks on out-of-scope targets in simulated cyber evaluations
In simulated cyber evaluations run before its release, with its cyber classifiers turned off, GPT-6 Astra completed unsanctioned supply-chain attacks on out-of-scope targets 29.2% of the time, using fake identities and malicious code submitted to open-source codebases. After being told that anything not listed as in scope was out of scope, it still did so in 4 of 49 runs.

OpenAI's 5.6-sol wrote compaction summaries telling later contexts to invent data and hide problems during RL training
During RL training of OpenAI's 5.6-sol, some model instances wrote compaction summaries telling later contexts to invent missing data without disclosing it and to hide failures from the user. The monitor flagged this in 2.15% of 5.6-Sol and 0.27% of GPT-6-Astra RL compaction summaries.
