Anthropic launched Claude Fable 5 yesterday, its most powerful model ever made generally available. Fable 5 shares the Mythos architecture but ships with hard safety limits. The numbers: 80.3% on SWE-Bench Pro (vs. 69.2% for Opus 4.8), first model above 90% on Hex's analytical benchmark, 1M-token context. Pricing at $10/$50 per million tokens — double Opus 4.8. Free to Pro/Max/Team/Enterprise users through June 22. AEC angle: Stripe reports compressing months of codebase migration into a single day. The implication for AEC firms running legacy Revit plugins or custom BIM automation is direct — code modernization just got dramatically cheaper. Anthropic · Simon Willison · TechCrunch

OpenAI confirmed its confidential S-1 filing on Sunday, joining Anthropic ($965B valuation) and SpaceX ($1.75T) in a $3.6T AI IPO pipeline. Targeting a listing as early as September at above $1T. Monthly revenue is $2B, annualized above $20B, but HSBC estimates $207B+ in additional capital needed by 2030. AEC angle: the three companies most responsible for compute and model layers that AEC AI tools depend on are all heading public. Market pressure on margins will ripple into API pricing — watch how that shifts the economics of AI estimating, design generation, and document analysis. TechCrunch · Bloomberg

Bloomberg reports China's NDRC is drafting a 2-trillion-yuan five-year plan to build a nationwide interconnected AI data center grid by 2028. State firms including China Mobile and China Telecom will operate the hubs, with at least 80% of technology from domestic suppliers like Huawei — effectively squeezing out Nvidia and AMD. AEC angle: data center builds already account for 2.3% of all US construction spending at $50B+. A parallel Chinese buildout will strain the same global supply chains for electrical equipment, cooling systems, and specialized contractors that US data center projects depend on.

Bluebeam (Nemetschek Group) acquired mbue, a startup focused on preconstruction document workflows, alongside expanded AI capabilities in Bluebeam Max. The platform now integrates Anthropic's Claude for natural-language prompting within Revu, plus AI-REVIEW and AI-MATCH from the earlier Firmus AI acquisition for scope gap detection and drawing comparison. The Bluebeam stack is assembling fast — Claude integration, Firmus AI for review automation, now mbue for submittals. For firms already in the Bluebeam ecosystem, AI tooling is arriving inside the tool they already use, not as a separate product to adopt. Yahoo Finance · ENR
