OpenAI's new AI model, GPT-4.5, has received mixed feedback, particularly regarding its underwhelming performance compared to earlier models. CEO Sam Altman announced that GPT-4.5 represents the final traditional model, with future development shifting towards a hybrid of large language models and simulated reasoning models like o3. Concerns have also arisen over GPT-4.5's pricing, which is significantly higher than GPT-4o, making it less viable for many developers, especially when alternatives like the more affordable o1 pro and o3-mini models offer better performance for certain tasks. This change indicates OpenAI's acknowledgment of the limitations of scaling up LLMs, prioritizing innovative inference methods instead.

Hospitals and health systems in the U.S. have been targeted by fraudulent data extortion letters purportedly from the Russian ransomware group BianLian, raising alarm among healthcare organizations and law enforcement. These letters threaten the disclosure of sensitive patient information unless a ransom is paid, yet they lack evidence of stolen data and reliable contact information. John Riggi from the American Hospital Association highlighted the unusual use of traditional mail for such extortion attempts and suggested these may be hoaxes. He urged recipients to report the letters to the FBI and to preserve them for forensic analysis, while the AHA continues to collaborate with law enforcement to address the ongoing cyber threats facing the healthcare sector.
