A2A Surface — Generally available

A2A is out of beta with Agent-to-Agent protocol 0.3 alignment, stable agent card URLs, and consistent artifacts and status across the task stream.

a2aagentsmulti-agent

A2A graduates from beta with full alignment to the A2A protocol 0.3 response shapes, agent card hosting at both agent-card.json and agent.json, and consistent artifact and status handling between SSE streams and persistence—so external agents and Runtype-hosted agents interoperate without one-off shims.

Multi-agent setups and skill-based routing built on the A2A surface are now supported as a stable product path, not a preview.
