OpenAI is working on a new cybersecurity product that will only be available to a small group of companies. That’s the word from Axios, and it tells you everything you need to know about where we are in 2026: the AI security arms race is heating up, and the big players are getting selective about who gets to play.
The company is releasing this new cyber model to a limited group of users, positioning it as a direct competitor to Mythos. The goal? Better software vulnerability detection. The catch? You probably can’t use it yet.
What We Actually Know
Here’s what OpenAI is offering: cybersecurity professionals will get to test their most capable offerings under reduced constraints for probing vulnerabilities. Translation: they’re loosening the safety rails so security researchers can actually do their jobs without the AI refusing to help because it thinks you’re trying to hack the Pentagon.
The initial rollout will let hundreds of users test the new model. OpenAI plans to increase the number of participants in the early access program later, but right now, this is a VIP-only situation.
The Toolkit Reviewer’s Take
I’ve tested enough AI security tools to know that this restricted release strategy is both smart and frustrating. Smart because you don’t want your vulnerability-finding AI in the wrong hands. Frustrating because the people who could benefit most from this technology are often small security teams at mid-sized companies who won’t make the cut for early access.
The real question is whether this model actually delivers on the promise. We’ve seen plenty of AI security tools that sound impressive in press releases but fall flat when you’re staring at actual code. Can it find zero-days that human researchers miss? Does it generate false positives that waste your team’s time? How does it handle obfuscated code or novel attack vectors?
I can’t answer those questions yet because I haven’t tested it. Neither have most of you reading this.
The Mythos Factor
OpenAI is explicitly positioning this as competition with Mythos, which tells us the cybersecurity AI space is becoming a real battleground. When major AI labs start racing each other to build better security models, that’s usually good news for the industry. Competition drives improvement.
But it also fragments the market. If every AI lab releases their own proprietary security model with restricted access, we end up with a two-tier system: companies with the right connections get access to the best tools, and everyone else makes do with whatever’s publicly available.
What This Means for Your Security Stack
If you’re a security professional hoping to add AI-powered vulnerability detection to your toolkit, this announcement is both promising and premature. Yes, OpenAI is building something that might be genuinely useful. No, you can’t use it yet unless you’re one of the chosen few.
My advice? Don’t wait around for an invitation that might never come. There are other AI security tools available now that you can actually test and deploy. Some are good, some are overhyped, but at least they’re accessible.
When OpenAI does expand access to this cyber model, I’ll be first in line to put it through its paces. Until then, this is just another announcement about a tool most of us can’t use. The AI industry loves to talk about democratizing technology, but restricted releases like this remind us that access still depends on who you know and how big your company is.
The race with Mythos might be heating up, but for most security teams, it’s a race we’re watching from the sidelines.
