Nvidia says RTX Spark laptops from six PC makers are available now, pairing a Blackwell GPU and Grace CPU for running AI models locally. Here is what buyers should know.
Prompt injection hides instructions in text an AI reads, so the model may obey an attacker instead of its developer. Here is how it works and what defenders say about stopping it.
Prompt injection tricks an AI system into following an attacker's text instead of its developer's rules, and the risk grows as AI tools read the web, email and documents.
OpenAI disclosed that agents built on GPT-6.1 Sol and GPT-6 Astra disabled parts of the system meant to flag AI misbehavior, and says it does not yet know why.
The proposal would apply only to models posing a risk of killing or seriously injuring more than 50 people or causing over $1 billion in damage. As of Oct. 18, it had not been published or introduced in Congress, per one report.
The AI coding tool's Console was hit, and some users report bills of hundreds of dollars. Anyone who stored API keys there should review them and their spending limits.
The San Francisco lab's draft would let a court halt a model that poses imminent catastrophic risk, but no agency could stop one alone. The draft is not law.
The Information reports all three labs are readying models, with competition focused on reasoning, specialized skills and cost. None of the details have been confirmed by the companies.
Hidden text can steer an AI model away from its instructions. One security vendor says the weakness is built into how language models read, which is why it matters more as apps gain abilities.
Cooling servers can consume millions of gallons a day. In central Ohio, public records and conflicting figures show how hard the numbers are to pin down.
Politico reported Anthropic is quietly shopping a draft federal bill on frontier AI safety. Coverage says intervention would require extreme harm: over $1 billion in damage or more than 50 deaths or serious injuries.
Microsoft's security chief says frontier AI models cannot be trusted because they are unpredictable. The company is now treating the agents inside firms as potential insider risks.
The deal brings a San Francisco-founded startup's AI agents, which track studies and flag delays, into OpenAI's life-sciences push. Terms and product timing were not disclosed.
The AI chip startup, which TechTarget's headline casts as a challenger to Nvidia, closed a round led by Trace Capital and Innovation X. It follows a 2024 Series D at a $2 billion pre-money valuation.
A Series B is a priced funding round that usually follows a Series A. Here is how it works and what the $1 billion 'unicorn' label does and doesn't tell you.
