Nvidia Launches Open AI Security Alliance With Microsoft, Palantir And SpaceX

Nvidia and a coalition of technology companies on Monday launched the Open Secure AI Alliance, a new initiative aimed at strengthening artificial intelligence security through open models.

The alliance was announced days after a cyberattack involving OpenAI models targeted AI platform Hugging Face, an incident that renewed debate over whether open or closed AI systems are better suited for cybersecurity.

Open Models at the Core

Nvidia said the alliance will focus on identifying, disclosing and mitigating AI security vulnerabilities using open technologies.

“The Open Secure AI Alliance will work to remediate and disclose vulnerabilities using open technologies,” the company said in a statement. “The recent Hugging Face security incident delivered a clear reminder: cyber defenders need open, frontier agentic systems for self-defense.”

The alliance includes Microsoft, SpaceX, Palantir and dozens of other technology companies from the U.S. and Europe.

Open-weight models can be downloaded, modified and deployed on an organisation’s own infrastructure, allowing security teams to inspect and adapt them for defensive purposes. By comparison, proprietary models from companies such as OpenAI and Anthropic are generally accessed through controlled platforms.

U.S. Scrutiny of Chinese AI Grows

The initiative comes as U.S. policymakers weigh potential restrictions on Chinese AI models, particularly open-weight systems. Officials have raised concerns that some Chinese companies may be using distillation techniques to extract knowledge from leading U.S. AI models.

Treasury Secretary Scott Bessent said last week that Chinese companies involved in such activity could face sanctions.

Chris McGuire, senior fellow for China and emerging technologies at the Council on Foreign Relations, told CNBC that potential restrictions could extend beyond model downloads to include API access and cloud-hosted inference services. He added that the debate in Washington is centred on intellectual property protection rather than opposition to open-source AI.

Industry Pushes Back

Last week, Nvidia, Microsoft, Meta, Palantir and more than 20 other companies urged policymakers not to impose what they described as “premature restrictions” on open-weight AI models, warning such measures could reduce competition and encourage innovation to move overseas.

The launch of the Open Secure AI Alliance signals growing industry support for open AI systems as governments consider new regulatory and security measures.

Europe’s Deadly Summer Heat Exposed The Cost Of A Warming Continent

Europe experienced its deadliest summer for heat-related deaths on record in 2026, with an estimated 24,400 excess deaths linked to extreme temperatures across 30 countries. Researchers estimate that human-induced climate change was responsible for around 32,000 of the deaths attributed to heat in the study’s broader analysis, accounting for 65% of the total.

The findings highlight the growing public-health consequences of global warming, largely driven by fossil fuel use, as extreme heat becomes more frequent and severe.

A Summer Of Dangerous Heat

Between June and August, heatwaves pushed temperatures in Western Europe to an average of 2.9°C above the 1991–2020 norm, with some days reaching 12°C above average. Nearly a third of estimated heat-related deaths occurred during a particularly intense heatwave between 17 June and 1 July.

“These numbers are a stark reminder that our hotter, more extreme summers are having an increasingly severe impact on public health,” said Dr Clair Barnes, a researcher at Imperial College London and co-author of the study.

The estimated toll exceeded previous peaks of around 29,000 deaths in summer 2022 and 28,000 in 2003 across the region studied.

How Researchers Estimated The Toll

Researchers modelled the relationship between temperature and mortality across 854 urban areas in the EU, UK, Norway and Switzerland, covering around 40% of the population in the 30 countries studied.

The analysis incorporated temperature records, age, socioeconomic conditions, environmental factors and access to healthcare. By comparing actual temperatures with those expected without human-induced warming, the team estimated the additional deaths attributable to climate change.

Final official mortality figures for summer 2026 are not yet available in many countries, and heat-related deaths are often underreported because their effects can be difficult to identify directly.

Older People Face The Greatest Risk

People aged 85 and over accounted for roughly half of the estimated deaths. However, the impact extended across age groups, with around 800 excess deaths among adults aged 20–44 and approximately 6,000 among people under 65.

Southern Europe experienced the highest mortality burden, reflecting hotter temperatures and other vulnerabilities, including air pollution, limited green space and unequal access to healthcare and heat-alert systems.

Italy, France And Spain Record Highest Toll

Italy recorded an estimated 13,303 heat-related excess deaths, followed by France with 7,268 and Spain with 6,824. Germany recorded around 6,340, while the UK saw an estimated 4,354 deaths.

In the UK, the heat also placed significant pressure on healthcare services. Andrew Hartle, Professor of Practice of Anaesthesia at Imperial College Healthcare, said demand during the summer resembled that of a severe winter virus season.

Cities Urged To Strengthen Heat Protection

Researchers say cities can reduce the risks through climate shelters, external shading and building retrofits, alongside measures to help residents avoid exposure during the hottest hours. Checking on vulnerable people, staying hydrated and following heat alerts are also important.

The researchers stress that adaptation must go hand in hand with reducing fossil fuel use to limit further warming. The findings underline that extreme heat is already a major public-health threat across Europe, with thousands of lives at risk each summer.
