Summary
The AWS Open Source Blog introduced Infinity, a research runtime developed with UC Berkeley as part of the Hydro project, aimed at supporting extremely high-concurrency AI agents. Infinity suspends and resumes agents using stackless coroutines before and after tool calls, supporting thousands of co…
Key points
- Teams building multi-agent long-running task platforms can first validate concurrency models and cost structures with the open-source runtime.
- For agents to truly scale, the bottleneck is the runtime's concurrency and wake-up mechanisms, not the model itself.
- Platform teams can evaluate replacing long polling with coroutine suspension to reduce memory and compute costs, but should note it is at the research stage.
