Llama 1 vs Llama 2 (Comparison)

討論

  • 雖然關於 “open source” 這詞有爭議、有各種詮釋角度?!1 但 Meta AI 這一步,也許可以取得 Edge AI 的先期導入佔比?
  • 七億 MAU 以下,請別想太多,盡情創造無腦玩?!
  • 期待更多測試、比較結果,各種模型或是工具,應有其優缺點、適用性。
  • 同一天 (2023-07-18) AWS Blog 也發布一篇 Llama 2 foundation models from Meta are now available in Amazon SageMaker JumpStart | AWS Machine Learning Blog,推測 Meta 應該也有與 AWS 密切合作,才能在 2023-07-18 同時發表?而 Meta Blog 與新聞稿卻是與 Microsoft 聯名,頗有趣。

  1. Meta launches Llama 2, an open source AI model that allows commercial applications | Ars Technica Although Llama 2 is open source, Meta did not disclose the source of the training data used in creating the Llama 2 models, which Mozilla Senior Fellow of Trustworthy AI Abeba Birhane pointed out on Twitter. Lack of training data transparency is still a sticking point for some LLM critics because the training data that teaches these LLMs what they "know" often comes from an unauthorized scrape of the Internet with little regard for privacy or commercial impact. ↩︎
