WHY DID META OPEN-SOURCE LLAMA 2?

Summary from the TLDR Web Dev newsletter

This article presents an in-depth analysis on why Meta made Llama 2's weights commercially available. Llama 2's license provides hints to Meta's goals: it prevents Llama materials from being used to improve other models and forces big tech competitors with more than 700 million monthly active users to request a license from Meta. This suggests Llama 2 was open-sourced to reduce competitor moats, retain AI talent, attract more users and developers, and act as a marketing tool.
