优势与取舍
优势所在
- Runs fully on-device — no network, no fees
- ~6GB VRAM at Q4 — fits entry GPUs
- Fastest FLUX.2 tier at 90 img/s-class throughput
需要注意的权衡
- Noticeably below Pro on fine detail and text
- Low-resolution ceiling vs. 32B tiers
- Struggles with long, complex prompts
杀手级用例
On-device apps
Offline image generation inside mobile/desktop apps.
Edge & IoT rendering
Local synthesis on embedded hardware.
Drafting loops
Cheap instant previews before a Pro render.
