long-running tools can report progress without blocking. nested agents stream their responses properly. crucial for production agent orchestration where you need visibility at every level.

we've always used vercel's ai sdk for model routing and streaming. but with ai sdk v5, rather than shipping breaking changes. we upgraded our agent orchestration capabilities. more user control, no upgrades necessary

not only does mastra support ai sdk v5 now. we've added additional agent orchestration capabilities. with more control over the agent loop and tool calling. plus a new streaming layer w/ support for nested streaming.

Mastra now controls the agent loop and tool calling with increased orchestration capabilities—while maintaining backward compatibility with AI SDK v4 and v5.
