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:

**Quick Start:**

```
git clone https://github.com/kvcache-ai/AgentENV
cd AgentENV && cargo build --release
./target/release/agentenv --node-id node1
```

**vs Alternatives:**

| AENV | Ray | Kubernetes | |
|---|---|---|---|
| Isolation | micro-VM | process | pod |
| Cold start | 50ms | ~1s | ~1s+ |
| Snapshot/fork | ✅ <100ms | ❌ | ❌ |
| Agent-native | ✅ | ❌ | ❌ |
