Anthropic Confirmed Claude Mythos Release — But Delayed Due to Safety

Anthropic has officially confirmed plans to release Claude Mythos to a wider audience. The company has delayed the release due to safety concerns regarding both open source code and closed commercial systems.

What is Claude Mythos

Claude Mythos is the next generation of models from Anthropic, promising significant gains in power and capabilities. The company does not disclose exact specifications, but the context is clear: this is a qualitative leap in performance. These could be tools for automated data analysis, content creation, programming, and scientific computing at scales currently limited even within the company. Anthropic has already built a reputation for a cautious approach to deploying new technologies. Following Claude 3 and 3.5, the company maintains a dialogue about risks and responsibility. Mythos represents an even larger step, and this is precisely why the decision to delay the release appears logical.

Why is the company concerned

Anthropic indicates that the delay is driven by safety concerns regarding open source code and closed commercial systems. The more powerful a model, the higher the risk of adaptation for malicious purposes — from cyberattacks to scaled phishing campaigns. For commercial software, the situation is more complex: integrating such a model could introduce new vulnerabilities in corporate systems. The company is concerned about the following scenarios:

• Scaling social engineering and phishing campaigns
• Automating vulnerability discovery in critical software (healthcare, energy, finance)
• Creating convincing disinformation content at scale
• Privacy violations through personal data analysis
• Bypassing existing security systems

When is the release?

Anthropic confirmed its intention to release Claude Mythos but did not provide a specific timeline. The company is conducting additional security checks and considering various distribution models: a fully open model, licensed access for verified companies, limited closed distribution, or an API with usage controls.

What does this mean

Even AI industry leaders are not rushing to launch powerful models — the current landscape requires a balance between innovation and safety. For developers, this means Claude Mythos remains on the horizon, while current Claude versions remain the primary tool. However, the very fact of confirmation suggests the release is a matter of months or a year away.
