AgentENV: Distributed Runtime for AI Agents at Scale (Open Source, Rust)

AgentENV (AENV) is a Rust-based distributed platform for running AI agent environments at scale, now powering Kimi K3's agentic RL training.

Why It Matters: Most agent frameworks are single-process toys. AENV makes agents distributed with Firecracker micro-VMs:

50ms cold start — snapshot environments boot or resume in <50ms

Incremental snapshot/fork <100ms — fork a running environment into independent sandboxes

Overlaybd OCI images — no pre-pulling, cluster-wide cache, images can exceed disk capacity
