Summary

Enthropic has launched a preview of Claude Mythos, a frontier AI model with "insane cyber capabilities" and agentic coding/reasoning. It achieved 93.9% on Swaybench Verified and 77.8% on Swaybench Pro, a 45% improvement over Claude Opus 4.6's 53.4%. Mythos also scored 82% on Terminal Bench 2.0, surpassing Opus 4.6's 65.4%. The model is so powerful it can identify and exploit software vulnerabilities, including zero-day flaws, leading to the creation of Project Glass Swing, a cybersecurity initiative involving Amazon Web Services, Apple, Google, Microsoft, and Nvidia. Mythos is priced at $25 per 1 million input tokens and $125 per 1 million output tokens, using up to five times fewer tokens than Opus 4.6 while being faster and outperforming it. Additionally, DeepSeek version 4 is undergoing limited grayscale testing, and the ZAI team released GLM 5.1, an open-source model ranking number one among open-source models and third globally across several benchmarks.

Key takeaway

For CTOs and VPs of Engineering evaluating AI adoption, Claude Mythos signals a critical shift in AI's security implications. You should prioritize assessing your organization's cybersecurity posture against advanced AI-driven threats and consider participating in initiatives like Project Glass Swing to leverage frontier models for defensive purposes. The model's token efficiency also suggests a re-evaluation of cost-performance metrics for AI deployments.
