The American company Anthropic has spent the past months since unveiling its latest innovation in artificial intelligence under the name “Cloud Mythos” warning of the cyber capabilities of the new model and the risks it carries in terms of cyber security, to the point that it created a new project called “Glass Wing” and granted 50 global companies and institutions direct access to the model.
These fears caused “Mythos” to be surrounded by an aura of secrecy and danger until a group of hackers was able to access the model and use it, so Anthropic decided to release it to subscribers to its services at no additional cost for a temporary period, which raised many questions about the model and the danger of presenting it to the public, according to a report by the American Bloomberg Agency.
However, if the “Mythos” was so dangerous that Anthropic was reluctant to release it to the public and chose to give financial institutions, companies, and governments prior access to the model, then why release it now?
What’s special about “Mythos”?
The Cloud Mythos model belongs to the category of general-use artificial intelligence models, which provide higher capabilities than others in several sectors and at several different levels, including, of course, the programming and cybersecurity sector, according to the Bloomberg report.
Thanks to these capabilities, “Methos” can examine the software codes of companies, banking institutions, and others in search of vulnerabilities, and then he can build hacking tools capable of exploiting these vulnerabilities, which are usually of the “Zero Day” category, meaning that “Methos” is the first to find them.
The Bloomberg report states that the organizations that participated in the limited access model of “Mythos” were able to find thousands of “Zero Day” vulnerabilities, including vulnerabilities in all prominent Internet browsers and also vulnerabilities in various operating systems, which are vulnerabilities that companies did not realize existed until after the “Mythos” experience.
“Methos” reinforces the fears among financial institutions and experts about the cybersecurity capabilities of artificial intelligence, which make it a real threat to them if it falls into the wrong hands, according to previous reports.
Did Anthropic overstate the model?
A report by the British newspaper “The Guardian” reveals criticism directed against Anthropic due to the “Claude Mythos” model since its first appearance, as some experts believe that it exaggerated the description of the “Mythos” capabilities.
This point of view clearly appears in experts’ posts on social media platforms dedicated to programming experts, such as Medium and Reddit, as some believe that the narrative promoted by Anthropic exaggerates the power of the model in a way that is not commensurate with its demonstrated capabilities.
Mythos is hyped – Am I the only one who feels like the Mythos narrative is hyped a lot compared to what’s actually been shown?

In contrast, companies and governments that gained access to Methos before it was released to the public confirm that its capabilities and resulting concerns are very real, as companies were able to find and fix thousands of vulnerabilities using the model.
The United States government also emphasized the capabilities of the model despite the tense relationship between the government of US President Donald Trump and Anthropic.
Tighter restrictions
Diane Penn, Head of Product Management at Anthropic, explained during her conversation with the American technology website “Wired” that the company spent the past months confronting the issue of how to deal with the model’s capabilities to discover security vulnerabilities and its other advanced features, which ultimately led them to offer a watered-down version of the model to the public and keep the more powerful version exclusively for companies.
Therefore, the company launched a version called “Cloud Mythos Fable 5”, which is a reduced version of “Mythos 5” that carries all the capabilities of the model, but with more stringent security restrictions. These restrictions prevent “Mythos” from answering questions related to cybersecurity or biosecurity in general, as the model automatically moves to “OPS 4.8” to answer these questions.
Ben confirms to Wired that this approach was the best among all the solutions proposed, as it ensures that users obtain all of the capabilities of “Mythos” but in a safe manner that does not represent a real danger.
Why did you bring it up now?
The launch of “Fable 5” now reflects the commercial tension that Anthropic is experiencing. On the one hand, it seeks to introduce the most powerful artificial intelligence models to attract users and companies from different categories, and at the same time it fears the negative effects of such models.
Anthropic is facing intense pressure from its competitors, led by the American OpenAI, developer of GBT Chat, which previously announced a new strategy targeting corporate clients instead of individuals in a direct attempt to compete with Anthropic.
Therefore, the company needed to introduce its strongest models in order to strengthen its position in the artificial intelligence sector and keep its customers from moving to other models and companies.
The launch of the model also coincides with the approaching offering of the company’s shares on the American stock exchange for the first time. The company’s valuation before being floated on the stock exchange approached $965 billion, according to a separate report from Reuters news agency, and this value is expected to increase as soon as the company’s shares are listed on the stock exchange.
