OpenAI Launches "Patch the Planet": Aims to Fix Security Flaws Before Mythos is Deployed
In Short
OpenAI has launched "Patch the Planet," a new cybersecurity initiative aimed at helping open-source developers fix software vulnerabilities more quickly. While AIs like Anthropic's Mythos can already detect flaws on a large scale, OpenAI says fixing them remains the biggest challenge.

OpenAI has announced "Patch the Planet," a new initiative designed to help open-source software projects detect and fix security vulnerabilities before they can be exploited. The program is part of OpenAI's broader "Daybreak" cybersecurity initiative and comes amid a growing race to use AI to discover and fix software vulnerabilities. In particular, this launch is seen as OpenAI's response to Anthropic, whose Mythos models have garnered attention for their ability to identify software vulnerabilities on a large scale.
The announcement was made alongside several Daybreak updates, including a more capable GPT-5.5-Cyber model, a new Codex security plugin, and an expanded network of cybersecurity partners.
What is OpenAI's "Patch the Planet"?
Essentially, "Patch the Planet" aims to address what OpenAI sees as a growing cybersecurity problem. While AI is becoming increasingly effective at detecting software vulnerabilities, developers often lack the time, resources, and expertise to investigate and fix every issue.
This increase in AI-powered vulnerability detection presents a new challenge for open-source developers. Open-source software powers everything from websites and browsers to cloud services and critical infrastructure; however, many of these projects are maintained by small teams or even volunteers. As AI tools generate an increasing number of vulnerability reports, developers find it more difficult to distinguish genuine security threats from duplicate reports and false positives.
"Patch the Planet" is OpenAI's attempt to address this problem. The company has partnered with security research firm Trail of Bits, as well as HackerOne and Calif, to offer free security assistance to open-source projects. The initiative combines AI-powered vulnerability detection with human security experts who validate findings, develop patches, test fixes, and coordinate responsible disclosure. This allows maintainers to focus on fixing real security issues instead of managing a growing backlog of reports.
According to OpenAI, all vulnerabilities identified through the program are reviewed by security engineers before being communicated to maintainers. This human review process aims to reduce false alarms and ensure that developers dedicate their time to fixing real problems rather than reviewing questionable reports.
OpenAI says the program has already yielded promising results. During an initial five-day phase, Trail of Bits assigned 25 engineers to work on 19 open-source projects. This initiative reportedly identified hundreds of security issues and led to dozens of patches. Researchers also developed AI-assisted testing systems capable of completing tasks that would traditionally take weeks or even months in days.
OpenAI's Response to Anthropic Mythos
The launch also highlights OpenAI's growing rivalry with Anthropic in the cybersecurity field. Earlier this year, Anthropic's Mythos models garnered attention for their ability to identify numerous software vulnerabilities across operating systems, browsers, and networking software.
OpenAI maintains that discovering bugs is only half the challenge. The more important task is helping developers validate the findings, write solutions, and deploy patches before attackers can exploit the vulnerabilities. The Patch the Planet initiative is designed to address this gap by taking AI-assisted cybersecurity beyond the discovery phase and into remediation.
Along with the announcement, OpenAI reported that its latest model, GPT-5.5-Cyber, scored 85.6% on the CyberGym benchmark, surpassing the 83.8% achieved by Anthropic's Mythos 5.
As AI continues to accelerate vulnerability discovery, OpenAI appears to be betting that the next phase of cybersecurity will not be about finding more flaws, but about fixing them faster.
