AWS Open-Sources Infinity: Rust Runtime Runs 75K Concurrent Agents on 8GB

AWS open-sourced Infinity, a Rust runtime for massively concurrent agentic systems that uses stackless-coroutine-style suspension to run 75,000 concurrent agents on 8GB of memory, with a novel "synthetic tool calls" mechanism for streaming asynchronous tool events back into agents.
