子 Agent
Subordinate agent units orchestrated by a lead agent, parallelized at scale to complete complex engineering tasks.
Anthropic launched Claude Fable 5.2 and Mythos 5.2 on a shared base model, with Fable for general users and Mythos restricted to vetted cybersecurity and life-science institutions. API pricing drops 20% versus the prior generation and generation speed rises up to 30%, while pre-release tests included 1,000+ sub-agents building a bootable OS prototype from scratch in eight days.
AI coding tool Amp released Spaces, where users describe a goal to a single lead agent that decomposes the work, spawns and coordinates multiple parallel agent threads, and surfaces progress as live cards. The feature shifts multi-agent orchestration from manual thread management to the agent itself, while letting team members request, comment and intervene in one shared chat, signaling a move from solo Q&A toward team-level task orchestration.
