Coding agents in particular went from novelty to infrastructure: OpenAI broadened Codex into a cross-role platform, Anthropic gave Claude Code dynamic multi-agent workflows, GitHub published a plan to keep up with the strain, and a wave of community harnesses (Lazarus, Gito, Dropbox's internal Nova) chased the long-horizon tasks the best agents still fumble.","On the model side, Microsoft staked out independence with its MAI family, NVIDIA's Nemotron 3 Ultra reached SageMaker, and Anthropic shipped a deliberately modest Claude Opus 4.8.","But the enthusiasm came with bills and breakage: Uber capped AI-tool usage after burning its annual budget in four months, BadHost exposed agent gateways, and attackers talked Meta AI into handing over Instagram accounts.","The biggest business news may
