The day in brief

Chainalysis said an outside actor accessed customer user IDs, names, email addresses and organization role labels using what it called “offensive agentic techniques” ¹. It found no evidence that investigation content, passwords, MFA secrets or session tokens were accessed, but its customer review remains incomplete ¹. Saudi Aramco completed its acquisition of 49% of HUMAIN, with PIF retaining 51% ownership ².

AI agents in a quantum-spin study rejected a result as inconclusive after controls failed, then retested with a revised protocol and obtained a run that passed preset criteria ³. A benchmark found rule violations in 918 of 2,304 answered runs across 19 enterprise-agent models, a 40% rate in simulated systems ⁴.

OpenAI will share usage allowances across ChatGPT and Codex for Plus, Pro and Business subscribers starting in December, excluding fast Chat ⁶. Northflank urged customers to treat environment variables as compromised and rotate stored secrets after reports of unauthorized AI-key use ⁸. Experts said reported hiker rescues do not establish that AI use is increasing accidents and warned that chatbot advice can weaken critical thinking ⁹.

• AI Agents Rejected an Inconclusive Quantum-Spin Run, Then Retested

  A study reports that AI agents treated an experiment as inconclusive after its controls failed, despite agreement with theoretical predictions. After revising the measurement protocol and testing it in pilot acquisitions, the team obtained a run that passed the preset criteria.

• Enterprise AI Agents Violated Rules in 40% of Answered Runs

  A benchmark of 19 AI models found violations in 918 of 2,304 answered enterprise-agent runs. The tests used simulated business systems and blocked every attempted change before it could take effect.

  cheapest way to learn reinforcement learning: - David Silver's RL lectures (free) - implement multi-armed bandits - code Q-learning from scratch - implement DQN on CartPole - learn policy gradients and PPO - train an agent in Gymnasium - read the GRPO paper and understand how it
