Artificial intelligence powerhouse OpenAI, the creator of ChatGPT, on Monday announced it is building a more open generative AI model as it faces growing competition in the open-source space from Chinese rival DeepSeek and Meta.

OpenAI on Monday said it raised $40 billion in a new funding round that valued the ChatGPT maker at $300 billion, the biggest capital-raising session ever for a startup.

One attack, many responses—organizations use various solutions to ward off online attacks. The playbooks that outline countermeasures also vary in their specifics. In the CyberGuard project, Fraunhofer researchers are working on standardized playbooks to help companies optimize their security strategies and align them with each other. The playbooks are generated by large language models and support the automation of IT security.

Researchers have developed "infomorphic neurons" that learn independently, mimicking their biological counterparts more accurately than previous artificial neurons. A team of researchers from the Göttingen Campus Institute for Dynamics of Biological Networks (CIDBN) at the University of Göttingen and the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) has programmed these infomorphic neurons and constructed artificial neural networks from them.

Over the past year, AI researchers have found that when AI chatbots such as ChatGPT find themselves unable to answer questions that satisfy users' requests, they tend to offer false answers. In a new study, as part of a program aimed at stopping chatbots from lying or making up answers, a research team added Chain of Thought (CoT) windows. These force the chatbot to explain its reasoning as it carries out each step on its path to finding a final answer to a query.
