1. Expecto Patronum！
Stable Diffusion！
咒語和他們的原理

2. 甚麼是 Stable diffusion？
唸咒 => 產出圖片
其他對手： MidJourney
爲什麼爆紅？
- 簡單易用沒 whitelist
- 可以自己架（去年你買到顯卡的話）
- NovelAI leak WAIFU

3. 甚麼是 Stable diffusion？
產出圖片
修改圖片
Inpainting/Outpainting

4. 開始唸咒吧

7. 開始唸咒吧

8. 開始唸咒吧

9. 開始唸咒吧

10. 開始唸咒吧

11. 所以結果會是這樣

12. 來看看咒語
爲什麼
+1girl
+best quality
- lowres
- poorly drawn
- bad proportions
就能產出好圖？ (Novel AI)

24. 自己跑咒語

換 model
E.g. https://huggingface.co/hakurei/waifu-diffusion
https://invoke-ai.github.io/InvokeAI/
升級了 macos 跑不了，囧
