Meta 的 LLaMA 宣稱是「The next generation of our open source large language model」，而 OSI 很早就有發文駁斥：「Meta’s LLaMa 2 license is not Open Source」。
在 OSI 的網站上可以看到「The Open Source Definition」，其中這條：
6. No Discrimination Against Fields of Endeavor
The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.
open source 不能限制使用，而 LLaMA 的授權限制了商業使用：
2. Additional Commercial Terms. If, on the Llama 2 version release date, the monthly active users of the products or services made available by or for Licensee, or Licensee’s affiliates, is greater than 700 million monthly active users in the preceding calendar month, you must request a license from Meta, which Meta may grant to you in its sole discretion, and you are not authorized to exercise any of the rights under this Agreement unless or until Meta otherwise expressly grants you such rights.
前幾天翻車的 CKIP-Llama-2-7b 目前都已經下架了，但可以在 Archive Today 的「CKIP Llama 2 7b Chat - a Hugging Face Space by ckiplab」看到存檔頁面，以及在 Internet Archive 上的「GitHub - ckiplab/CKIP-Llama-2-7b: CKIP Traditional Chinese Llama-2」看到 GitHub 當時的頁面。
當時看到 CKIP-Llama-2-7b 宣稱用 Apache License, Version 2.0 放出來，我就「蛤？」了出來...
Anyway，雖然是其他原因被下架了...
