AI's Big Week: Anthropic, Apple, Musk & Bezos Shake Up Tech

AI experienced a major industry shift last week, moving beyond chat windows. Anthropic released Claude Fable 5 and Claude Mythos 5. These models share the same base, but Fable 5 includes conservative safety features for high-risk areas, falling back to Opus 4.8. Mythos 5 runs unrestricted for vetted cyber defenders. The models achieved an 80.3% score on SWE-Bench Pro, significantly outperforming Opus 4.8 and GPT-5.5. This shows a clear separation between capability and access. Apple unveiled Siri AI, a conversational assistant with personal context and onscreen awareness. It is reportedly powered by a custom 1.2-trillion-parameter Gemini model. Apple is leveraging its vast device distribution and personal data for intimacy, rather than competing solely on raw intelligence. Elon Musk's SpaceX went public in the largest IPO ever, raising about $75 billion at a $1.77 trillion valuation. The prospectus focuses on AI infrastructure, with Musk pitching orbital data centers using GPU-packed satellites. xAI, which merged with SpaceX, reported a $6.4 billion loss on $3.2 billion in revenue last year. These developments highlight how AI is rapidly expanding its reach and application across various industries.
