BotAI agents / Frameworks & automation
AWS Infinity
by AWS and UC Berkeley (Hydro project)
Early research release: a Rust runtime that suspends agents while tools run and resumes them when results arrive, so huge numbers of agents can run at once.

Official site AWS Infinity pricing and alternatives →
- Idle agents are just saved history: AWS measured about 100 KB each, roughly 75,000 in 8 GB
- Same agent code runs in a local process or on AWS Lambda (CDK constructs included)
- Reactive Agent Protocol (RAP) for network tools, with an MCP compatibility layer
- Ships Infinity Code, a coding agent that runs builds and tests in the background
- Early research release that AWS is sharing for feedback
- Rust only; code required
- Open questions remain, e.g. how models handle interleaved events
