More companies are restricting employee use of AI tools after widely rolling them out, citing rising costs. Amazon, Walmart, Cisco, Uber and Meta are setting usage limits, curbing waste and steering staff to cheaper models as AI agents drive higher computing demand. Interest in low-cost models is growing, with surveys showing Chinese models leading U.S. rivals in token usage. Anthropic opened a Seoul office and OpenAI expanded activities in Korea, including an MOU on AI safety.

Amazon Web Services has announced three new services positioned as a context intelligence stack for AI agents. The core is AWS Context, which automatically builds knowledge graphs from existing data and learns agent usage patterns to improve itself. It combines semantic search and graph-level reasoning to identify relationships between tables, column meaning and source reliability, and deliver needed information when agents run tasks. Queries can be tracked by identity.
