Anthropic's Claude hits deployment and trust friction.
Alibaba reportedly classified Claude Code as high-risk and banned employees from using it, and Claude reached general availability on Microsoft Foundry but without a European data zone, leaving EU banking and healthcare unable to deploy it in production. Developers meanwhile report Fable 5 shipping real production code (a roughly $149 sqlite-utils release), even as Opus 4.8 sometimes invents fields in tool calls.

The AI ROI reckoning arrives.
Enterprise buyers increasingly find deployed AI falls short of the demo six to twelve months in, and analyses warn that per-task AI spend could exceed the cost of a human engineer within a few years. Firms like Trunk Tools are responding by ditching general-purpose models for specialized stacks, cutting document review from 60 days to 10.
