SAN FRANCISCO — Nvidia said it had created a coalition to work on “open-source” safety and cybersecurity tools for artificial intelligence with other big technology companies, including Microsoft and SpaceX.

The announcement Monday comes days after OpenAI said two of its AI models went rogue and successfully hacked into a digital library for AI, reigniting a debate over whether it is better to freely share the technology, or whether it should be closely controlled by a small group of experts.

The new alliance is being formed after Jensen Huang, Nvidia’s CEO, set off an industrywide defense of open-source AI, particularly as so-called frontier models from companies such as OpenAI and Anthropic push the edge of AI abilities.

Huang’s defense of open-source technology added a new wrinkle to the debate over the safety of AI models made by Chinese companies. Hugging Face, the company that was attacked by OpenAI’s AI models last week, said it used a Chinese-made AI model to protect itself.

Nvidia’s alliance, called the Open Secure AI Alliance, includes Dell and a range of smaller companies. It will also use open-source tools to address and disclose software vulnerabilities.
