Fable 5 is the first Anthropic model available to the public that is based on Mythos, the most advanced artificial intelligence ever developed by the company led by Dario Amodei. It is now available on the market, including the Italian one. However, there are limitations.
The update was announced with a notification arrived to Claude users. We intercepted it too. For a few hours now there has also been one of the models developed by Claude that can be chosen in Italy Fable 5the first available based on the Mythos family. In Claude’s app this model is presented as an ally “for your toughest challenges”. And indeed Mythos should be something very different from AI models that we have seen so far. The logo is a 5 made with butterflies.
We’ve already been talking about Mythos ad Aprilespecially in the field cybersecurity. Dario Amodeifounder of Anthropic, explained that it could not be released to the public right away. It is a model that is too advanced, especially in some areas. Mythos was able to find thousands of bugs in the software of the main Big Tech companies in the United States. Code errors that had previously gone unnoticed.
This launch had worried many analysts. If Mythos is able to navigate such complex analyses, there is a risk that software on which entire markets rely could be attacked at the same time. The Wall Street Journal he had coined the term Bugmageddon: an apocalypse of bugs discovered by new artificial intelligence models that would overwhelm the digital world. Just a week ago with the Meta AI – Instagram case we saw what can happen when users find a way to exploit a bug to obtain information.

How Fable 5 works: Anthropic’s two-speed model
Anthropic has been trying to in recent months stand out as an ethical company. He stepped back from the contract with the Pentagon, called for a pause in the development of the most advanced artificial intelligence systems and seeks to present themselves in a way that is distant from OpenAI. Of course, this distinction between good and bad marked by the narrative on artificial intelligence still skips some steps related to the history of Anthropic.
In any case, Anthropic has decided to launch this model with limitations: the objective is to avoid accidents in the most sensitive fields. The company explained it in a post on its official blog: when the requests to Fable 5 regarding sensitive topics the model slows down. The answer that is given is no longer based on the Mythos algorithms but up Opus 4.8Claude’s model that currently ranks second on Anthropic’s power scale. Among these “sensitive topics” there is certainly cybersecurity.
According to Anthropic this system should ensure the safety of researchthus allowing its engineers to work on the next updates. For everything else, the capabilities of Fable 5 should become clear especially in the more complex analyzes as has also been recognized analytics company Hex.
Anthropic will be the most highly valued private company in the world
Anthropic is not yet listed on the stock exchange. As Kevin Roose and Casey Newton pointed out on the Hard Fork podcast, this could be one Hot IPO Summerthe summer in which all the Big Tech companies that remained outside the financial market decided to list on the stock exchange. In a few days it should be SpaceX’s turn, after this step all eyes are on OpenAI and Anthropic. However, when SpaceX presents itself to the markets, Dario Amodei’s company will become the private company with the highest valuation in the world: 965 billion dollars.
