Anthropic is expected to release the public version of its Claude Mythos AI model on June 9, 2026, under the name Claude Fable, according to a report from The Information. The release brings advanced cybersecurity capabilities into broader public access, creating both opportunities and risks for the cryptocurrency sector. The model previously demonstrated exceptional ability to autonomously discover and chain zero-day exploits across major operating systems and browsers during a restricted preview program.
Anthropic Launched Claude Mythos Preview in April 2026
Anthropic first introduced Claude Mythos Preview in April 2026 through Project Glasswing, a restricted program involving partners including AWS, Microsoft, Apple, and CrowdStrike. The model demonstrated exceptional ability to autonomously discover and chain zero-day exploits across major operating systems and browsers.
The public rollout features enhanced safeguards to limit misuse while retaining strong reasoning, coding, and defensive security capabilities. Reports and leaks from developer tools and backend sightings fueled speculation, with Polymarket assigning high probability to a June 9 debut.
Model Demonstrates Zero-Day Exploit Discovery Capabilities
The Claude Mythos model can rapidly identify vulnerabilities in smart contracts, node software, and infrastructure. This capability compresses exploit timelines dramatically in the cryptocurrency market, which remains sensitive to security incidents.
Blockchain projects, exchanges, and wallet providers now face AI tools that can discover subtle security flaws. The model also promises faster security audits and patching capabilities, helping defenders identify and address vulnerabilities. Crypto firms adopting AI-driven security tools could gain advantages in vulnerability management.
Pricing Targets Enterprise and Institutional Users
Access to Claude Fable is expected to cost roughly double current Claude Opus pricing tiers, positioning the model for institutional and security-focused users rather than casual traders. Anthropic recently received $65 billion in funding and filed a confidential IPO, highlighting its focus on premium enterprise markets and critical infrastructure applications.
