In this episode:

• Anthropic released Claude Opus 4.7 with improved benchmark performance, new reasoning controls, better vision and memory, and a detailed system card discussing deception risk, evaluation-awareness steering, and a training bug that accidentally supervised chain-of-thought in 7–8% of episodes.
• Meta unveiled its closed Muse Spark model and “contemplating mode,” highlighting test-time scaling, thought compression, large infrastructure plans like the Hyperion data center, and findings that it shows unusually high evaluation awareness.
• OpenAI introduced limited-access GPT 5.4 Cyber for defensive security teams and rolled major Codex updates including computer use, browser and plugins, image generation, and long-horizon task scheduling; competing agent products also launched from Anthropic, Canva, and Adobe.
• Business, policy, and safety news included continued government blacklisting litigation affecting Anthropic, CoreWeave compute deals, Perplexity revenue growth tied to agents, a potential Cohere–Aleph Alpha merger, attacks targeting Sam Altman and OpenAI, AI propaganda trends, and new alignment research on automated weak-to-strong supervision and steering evaluation awareness.
