The world of artificial intelligence has just reached a point where the line between a brilliant tool for developers and a dangerous tool for hackers has begun to blur. Anthropic, known for its emphasis on safety and ethics, announced the existence of the Claude Mythos 2 Preview model. This model is not just another step in advanced programming; it is an entity that can identify errors in code that developers are not even aware of.
What is Claude Mythos and why is it so dangerous?
Claude Mythos is a so-called "frontier model" – a cutting-edge model of the highest possible level, developed to test the limits of AI capabilities. According to official reports from Anthropic, these models have reached a level of coding that surpasses even the most experienced human experts in finding and exploiting software vulnerabilities.
The term zero-day vulnerability refers to a flaw in software that developers are not yet aware of and for which no fix (patch) exists. If an attacker exploits this flaw, they have free reign in the system. During testing, Claude Mythos found thousands of such high-risk flaws in almost every major operating system and web browser we use today. This includes systems like Windows, macOS, Linux, as well as browsers like Chrome or Safari.
This very capability is why Anthropic decided not to release the model to the public. The risk of such a tool falling into the hands of cybercriminals or state actors is simply too high. If Mythos could automate the discovery and subsequent exploitation of flaws, it could lead to massive destabilization of the digital economy.
Project Glasswing: A Digital Shield for the Future
Instead of simply "shelving" the model, Anthropic opted for a defensive utilization strategy. Together with partners within the Project Glasswing initiative, it aims to use Claude Mythos's capabilities to secure critical software infrastructure. The largest market players have joined this coalition, including Amazon Web Services (AWS), Apple, Google, Microsoft, NVIDIA, Cisco, and CrowdStrike.
The goal is for Mythos to help these companies in preventive code scanning, fixing bugs before someone exploits them, and strengthening the resilience of systems on which banking, healthcare, and energy depend. Additionally, Anthropic has allocated 100 million USD in credits for the use of Mythos within these defensive activities and 4 million USD in direct donations to organizations focused on open-source software security.
Capability Comparison: Claude Mythos vs. Competition
To understand the scope of Mythos's capabilities, it is necessary to compare it with current top models that are commonly available:
- Claude Mythos (Anthropic): Specialized in deep code analysis and finding security vulnerabilities. Represents the pinnacle in zero-day vulnerability detection.
- GPT-4o / GPT-5 (OpenAI): Excels in general programming, logic, and conversation, but its focus on deep cybersecurity analysis is primarily general.
- Gemini 1.5 Pro (Google): Offers a huge context window, which is great for analyzing entire code repositories, but Mythos shows higher accuracy in identifying specific exploits.
- Llama 3 (Meta): A powerful open-source model available to the general public, but it lacks the specific training focus on advanced cybersecurity that Mythos has.
Impact on Users and the Czech Market
What does this mean for you, the average user, or for a Czech company? At first glance, it might seem that you don't need to worry about things concerning "big players." However, the reality is different.
For average users: This technology paradoxically increases your security. Because AI finds a bug in a browser before a hacker does, software updates (Windows Update, browser updates) will come faster and be of higher quality. Your data in banking or on social networks will be safer thanks to Mythos's preventive work.
For Czech companies and the IT sector: The Czech Republic has a strong tradition in cybersecurity. For local companies that develop software or provide IT services, this news signals that standards for "secure code" are drastically increasing. Companies will need to integrate similar AI tools into their development processes to compete with global security standards.
European regulation (EU AI Act): In the context of European legislation, models like Claude Mythos fall into the category of high-risk AI systems. The EU AI Act places enormous emphasis on ensuring that systems with such a high capacity to affect critical infrastructure are under strict supervision. Project Glasswing is essentially a response to the need for transparency and security that the EU requires.
Availability and Price
It is important to emphasize that Claude Mythos is not publicly available. You cannot buy it or try it as part of a regular subscription.
- Standard Claude (e.g., Claude 3.5 Sonnet): Is available in Czech, works without problems in the Czech Republic via the web interface or API. The price for Claude Pro is 20 USD per month.
- Claude Mythos: Is available only to selected Project Glasswing partners and selected critical infrastructure management organizations.
Can Claude Mythos cause someone to hack my computer?
The model itself cannot. Anthropic deliberately does not release it to the public precisely to prevent misuse. The goal is for the model to serve to fix bugs, not to exploit them.
How will I know that my software is safer thanks to this technology?
You won't know directly, but you will see it in more frequent and important updates to your operating systems and applications. Developers will be able to "cure" bugs faster thanks to AI capabilities, which would take humans months.
Is Claude Mythos available in Czech?
Since it is a model focused on deep code analysis and cybersecurity, its primary language is programming code and English. However, for average users in the Czech Republic, the standard Claude, which handles Czech excellently, is still the best tool.
