Claude Opus 4.8 Tops Every Benchmark, Anthropic Hits $965B, Apple's Siri Finally Gets an AI Brain

Today we're covering the biggest AI stories of May 29th, 2026. Anthropic dropped Claude Opus 4.8 — beating GPT-5.5 and Gemini 3.1 Pro on agentic coding, computer use, financial analysis, and Humanity's Last Exam — while simultaneously closing a $65 billion raise that pushed its valuation to $965 billion, surpassing OpenAI for the first time in the company's history, with a Mythos-class public model coming in the weeks ahead. Apple is finally rebuilding Siri from the ground up on Google Gemini, with a dedicated ChatGPT-style app living inside Dynamic Island, AI-powered web search built in, and support for third-party agents including Claude and ChatGPT — arriving in iOS 27 as Apple's last real chance to be relevant in the AI era before John Ternus takes over as CEO. Plus, Cursor's Developer Habits Report shows lines of code per developer more than doubled in 18 months — but the top 1% of users are producing 46 times more code than the median, and the gap is widening every month — and today's community workflow comes from Gabriela in Austin, who used ChatGPT to build a custom personal style system — analyzing selfies, measurements, and inspiration photos — and now runs every outfit, haircut, and wardrobe decision through it daily.
