Llama 2: Not an Open Source LLM
Breaking News: Llama 2's Open-Source Status Clarified
Corrections to Misinformation
Despite widespread claims online, Llama 2 is not an open source Language Learning Model (LLM). This misinformation has been circulating, leading to confusion and incorrect assumptions about the project.
While certain components of Llama 2, such as weights and code, are publicly available on GitHub under an Apache 2.0 license, the critical aspect of the LLM — the API — remains closed source. This limits access and restricts the ability to modify and distribute the model in its entirety.
It's important to note that the permissive license applies only to non-commercial use cases. For commercial applications, additional licensing fees may apply. Therefore, the claim that the model is freely accessible and modifiable for the majority of users is inaccurate.
Experts in the field have emphasized the distinction between open source and open access. Llama 2, while having open access to certain elements, is not a fully open source LLM due to the restricted nature of its API.
