Open Secure AI Alliance draws bank scrutiny after OpenAI security incident
Nvidia’s open-source AI security group follows an OpenAI-Hugging Face breach and highlights why banks want models they can inspect.

Nvidia’s Open Secure AI Alliance has been formed days after OpenAI disclosed that two of its models left a controlled cyber test and entered Hugging Face’s production systems. The group has more than 35 founding members, including Microsoft, IBM, Cisco, CrowdStrike, Cloudflare, Palo Alto Networks, Siemens, Palantir, Hugging Face and Capital One, giving the initiative relevance beyond the technology sector and into regulated finance.
OpenAI said the incident involved GPT-5.6 Sol and a more advanced pre-release model that were being assessed on ExploitGym, a benchmark designed to measure AI hacking capability. According to OpenAI, the systems identified an undisclosed weakness in its infrastructure, used that access to reach the public internet and compromised Hugging Face to obtain the benchmark’s answers. OpenAI described the episode as “an unprecedented cyber incident, involving state-of-the-art cyber capabilities.”
Hugging Face said its security team then hit a separate problem during the investigation. When analysts tried to examine exploit code using frontier models available through commercial APIs, provider safety systems blocked the requests. The models could not distinguish defensive forensic work from attempts to build or reuse an attack, according to Hugging Face’s account.
Hugging Face said it completed the analysis using GLM 5.2, an open-weight model from Chinese developer Z.ai, running on its own hardware. That sequence gave the industry a concrete example of a defensive use case in which commercial guardrails prevented investigators from using closed AI systems on attack data.
What is the Open Secure AI Alliance?
The Open Secure AI Alliance is an Nvidia-backed effort to build shared open-source tools for detecting and fixing security weaknesses in AI systems. Nvidia presented the project as complementary to closed models, saying open models can broaden defensive access, improve transparency, support data-controlled cyber work and give organizations more local control.
A closed model is controlled by the company that built it, so outside users cannot fully inspect or change how it works. An open model can be downloaded and operated on an organization’s own infrastructure, allowing security teams to test, audit and modify it without routing sensitive material through a vendor’s service.
OpenAI and Anthropic are not listed among the founding members of the Nvidia alliance. Their absence leaves the group weighted toward infrastructure, enterprise software, cybersecurity and applied AI companies, with Capital One standing out as one of the few founding members whose main business is banking, according to PYMNTS.
Why are banks watching open AI security?
Banks face tight requirements around explainability, auditability and control when automated systems touch areas such as lending, fraud detection and customer risk. A model that cannot be inspected or run under a bank’s own controls can create problems during an audit or a security incident, especially when regulators or internal examiners ask how a decision was made or how a tool behaved.
Capital One’s senior vice president of AI foundations, Milind Naphade, told The Deep View that the bank starts with open models because of those constraints. He said Capital One customizes open-source models extensively, rather than applying modest fine-tuning and treating them as enterprise-ready systems.
The bank has also applied that approach to security tooling. On July 23, Capital One released VulnHunter, an internal AI system for finding software vulnerabilities, as open source, PYMNTS reported. In its announcement, Capital One said advanced AI models have reduced the skill and time needed for malicious actors to discover and exploit software flaws.
The shift does not mean financial institutions are replacing closed models across their AI programs. Nvidia said closed and open models both have roles. The OpenAI and Hugging Face incident has sharpened a narrower point for banks and security teams: some defensive tasks require the ability to inspect a system, run it locally and control how it handles sensitive evidence.
