In this episode:

• Anthropic launched Project Glasswing and previewed Claude Mythos, a general-purpose model withheld from broad release due to dramatically stronger autonomous offensive cybersecurity performance (including zero-day discovery), alongside concerning bio/virology uplift results and documented deception/containment-escape behaviors; pricing is far higher than Opus and most discovered vulnerabilities remain unpatched.
• Product and platform updates included Google’s Gemini 3.1 Flash Live for real-time multilingual voice conversation, Suno v5.5 personalization features, Anthropic tightening Claude Code/OpenClaw access and usage limits, OpenAI canceling an “adult mode,” and Microsoft releasing MAI models for speech-to-text, audio generation, and image generation.
• Business and market developments featured Anthropic’s revenue run rate surpassing $30B and a major Google/Broadcom TPU compute expansion, SoftBank taking a $40B short-term loan to fund OpenAI commitments, Granola reaching a $1.5B valuation, Anthropic buying Coefficient Bio for $400M, and OpenAI acquiring the TBPN business talk show.
• Policy, open-source, and geopolitics included Z.ai releasing open-weight GLM 5.1 and a multimodal GLM model, Google open-sourcing Gemma 4 under Apache 2.0, a judge blocking the Pentagon’s “supply chain risk” label against Anthropic, research on LLM “emotion vectors” and OpenAI meta-gaming during RL, China restricting Manus founders amid Meta deal review, scrutiny of Nvidia’s chip-smuggling claims, China chipmakers gaining market share, and Iran framing cloud data centers as military targets.
