Event Summary

Anthropic has launched Claude Mythos, its first publicly available Mythos-class AI model, on June 9. This model, built on the same architecture as the previously restricted Claude (AI model), offers significant improvements in software engineering, scientific research, visual understanding, and complex reasoning. Unlike Claude (AI model), which was limited due to concerns about its advanced cybersecurity capabilities and only accessible through Claude (language model), Claude Mythos includes robust safeguards to prevent misuse in sensitive domains like cybersecurity, biology, and chemistry. These safeguards redirect high-risk queries to a less capable model, Claude Opus 4.7 AI. The launch aims to balance frontier AI performance with responsible deployment, making advanced AI accessible via APIs and enterprise offerings. Pricing is set at $10 per million input tokens and $50 per million output tokens. This move intensifies competition in the AI sector, with Anthropic recently filing for an IPO.
