## AI 摘要

Atomic Chat 将腾讯开源 295B 参数 MoE（21B 活跃参数）模型 Hy3 极端压缩至 1-bit，生成 92GB GGUF 文件。在 4 块 RTX 5090（128GB VRAM）上本地运行，速度达同模型云 API 的 2.2 倍。测试中，本地版与云 API 版均能通过单次提示词生成 Flappy Bird、Arkanoid 和 Snake 游戏，无崩溃或明显视觉差异。输出对比：本地版 76.9K tokens / 15.5 分钟，云 API 版 75.1K tokens / 34.3 分钟。Hy3 采用 Apache 2.0 许可，可商用。

## 正文

This is so interesting for local LLM.

Atomic Chat compressed the 295B-parameter Hy3 （to an extreme 1-bit ） model into a 92GB file and ran it 2.2x faster than its cloud API.

They installed the model locally on 4x RTX 5090 with 128GB VRAM against the same Hy3 over cloud API.

The big deal is that the extreme compression kept useful quality after this extreme compression.

Both versions built working Flappy Bird， Arkanoid， and Snake games from one-shot prompts， with no crashes or obvious visual gap.

Outputs：
Hy3 1-bit local： 76.9K tokens， 15.5 min
Hy3 cloud API： 75.1K tokens， 34.3 min

Hy3 is Tencent's open-sourced Apache 2.0 licensed model， i.e. commercially usable by enterprises. A massive 295B MoE （21B active parameters）.
