The decision reflects internal findings that the upcoming ‘Astra’ model may possess ‘critical cyber capabilities’ and follows a string of AI-testing incidents.

OpenAI said on Friday it cannot rule out that its upcoming AI model, Astra, has "critical" cybersecurity capabilities, prompting the startup to ​pause some internal development and trigger safety protocols.

OpenAI revealed in a Sunday blog post that the LLM had solved 10 long-running math problems. The company published the proofs and revealed that each one took about $2,000 worth of tokens to generate.

That assessment has prompted OpenAI to tighten internal security around the model before any wider deployment. The company also plans to work with government agencies and independent AI safety groups to validate Astra’s capabilities and strengthen safeguards before release.

Opinions diverge on what it means for DeepMind's future as Google makes big changes to its AI leadership.

Jeff Dean, Google’s chief scientist, is leaving the company. Demis Hassabis, the Google DeepMind CEO who has led artificial intelligence (AI) development, is also stepping down as CEO and transitioning to the role of Alphabet chief scientist.

Hassabis will take on a new role as Google DeepMind chair and Alphabet’s chief scientist. Major leadership changes were announced at Google Wednesday.

Google DeepMind is undergoing a major restructuring following model delays and a string of high-profile exits.
