The news: Anthropic developed a model that it says is too powerful to release to the public, called Claude Mythos Preview.

Instead, the AI firm is making the model available to a coalition of over 40 tech companies—including Apple, Amazon Web Services (AWS), Google, and Microsoft—which will use Mythos Preview to identify and fix security vulnerabilities in software programs.

Even if marketers never directly touch models like Mythos Preview, they will likely feel the effects through safer ad platforms, more secure customer data environments, and potentially more robust AI-powered tools released down the line.

Zooming in: The coalition, called Project Glasswing, is a team effort to help labs, software companies, researchers, and governments stay ahead of AI models’ coding capabilities. Mythos Preview has already found thousands of high-level vulnerabilities, including some in every major operating system and web browser, per Anthropic.

“AI cyber capabilities at this level will proliferate over the coming months, and not every actor who gets access to them will be focused on defense. That's the gap Glasswing is built to close,” Anthropic president and co-founder Daniela Amodei wrote on LinkedIn.

The bigger picture: As AI advances, and as major players like Google and Microsoft ship more consumer-facing and enterprise features, the market becomes further entrenched in their ecosystems. If Big Tech companies can bake strong AI security into their setups at an earlier stage, marketers using those systems can benefit too.

• Amid the growth in AI-driven cyber capabilities, brands will face higher risks like data breaches, content manipulation, and fraud.
• Marketers will need to emphasize security, authenticity, and data management as part of brand positioning.

Project Glasswing also aids Anthropic’s broader mission of being a leader in AI security and safety testing, which has boosted consumer trust and adoption of Claude.

However, this coalition could further concentrate power among major platforms as the most advanced AI capabilities and strongest defenses stay behind closed doors. That makes marketers more reliant on Big Tech ecosystems for both innovation and security gains.

Recommendations for marketers: As AI risks increase and Big Tech players collaborate to address AI threats, marketers should prioritize platforms with strong, built-in security and evaluate partners on their ability to protect data and brand integrity.

• Invest in internal safeguards, including fraud detection and content verification, to reduce reliance on any single ecosystem.
• Monitor how tech companies are working together on information sharing and security to see who is staying ahead of AI cybersecurity and who is putting it on the back burner.
