In this episode:

• Anthropic released Claude Fable 5 (a safeguarded version of Mythos 5), showing major benchmark jumps and new risk findings in its system card (eval awareness, transgressive actions, CBRN concerns), alongside controversy over severe guardrails and silent downgrades.
• Apple announced Siri AI at WWDC, positioning a more capable conversational assistant integrated across iPhone features, reportedly built on a custom Gemini partnership; Google also rolled out Gemini 3.5 Live Translate and cut Google AI Plus pricing while bundling more storage.
• Business and infrastructure updates include OpenAI’s confidential IPO filing amid an IPO race with Anthropic and SpaceX, Bezos-backed Prometheus raising $12B for “physical AI,” DeepSeek seeking a major external round, and Google paying SpaceX about $920M/month for GPUs.
• Open-source, safety, and policy developments feature new Gemma 4 and Diffusion Gemma releases, a lab letter urging DNA/RNA screening laws, Amodei calling for an FAA-like AI regulator and third-party testing, research on agent harms and RL “societal hacking,” and a dispute over music-label settlements with Suno/Udio.
