## AI 摘要

社区开发者 @OrlandoLiuqn 基于面壁智能 MiniCPM5-1B 构建了 EdgeHome Harness——一个全栈 Rust 框架，将轻量 1B 模型转化为可靠的智能家居/垂直场景确定性控制器。整个堆栈仅需 2GB RAM（模型 688MB，运行时约 1GB；Rust Harness 25MB-64MB）。工作流程：用户命令 → MiniCPM5 生成候选 JSON → Rust 验证、规划、执行并追踪，模型从不直接接触设备。框架通过设备注册表与策略门（自动执行/确认/回退）强制安全边界，并内置 Trace/Replay/Eval 实现可观测与可重现。该工程原型证明小模型在合适框架下可可靠运行于边缘。

Big things come in small packages – and MiniCPM5‑1B proves it once again. 🥳
A developer in our community @OrlandoLiuqn built EdgeHome Harness – a full‑stack Rust framework that turns a lightweight 1B model into a reliable, deterministic controller for smart home and vertical scenarios:

⚡ Runs on just 2GB RAM
MiniCPM5‑1B (688MB, ~1GB runtime) + Rust Agent Harness (25MB‑64MB) – the entire stack fits comfortably in ultra‑constrained edge devices.

🧠 Model proposes, Harness disposes
User command → MiniCPM5 generates candidate JSON → Rust validates, plans, executes, and traces.
The model never touches devices directly – every candidate must pass room/device existence, capability checks, and policy gates (auto‑execute, confirm, or fallback).

🛡️ Handles common 1B‑model issues
Output Governor handles repetition, rambling, and malformed JSON. Rust manages short‑term memory (last_target, aliases) to avoid context bloat. Device Registry + Policy Gate enforce deterministic security boundaries.

📊 Fully observable & replayable
Trace / Replay / Eval make every failure reproducible and measurable – no more tuning by instinct.

This isn’t a commercial gateway – it’s an engineering prototype that proves: small models don’t need to be omnipotent. With the right harness, MiniCPM5‑1B works reliably at the edge. It’s about redefining the model‑system boundary, not cramming cloud AI into tiny boxes.
