Meta Faces Backlash Over False Open Source Claims for Llama 2
Meta releases its Llama 2 large language model and heavily markets it as open source, but critics point out that its custom license contains restrictive clauses. These limitations violate true open source principles and threaten to confuse the industry's understanding of software freedom.
Meta releases its new Llama 2 large language model to the public and aggressively markets it as an open source product. While users freely download the model and access its documentation, the company applies a custom license rather than an approved open source agreement. This distinction causes significant concern within the technology community, as the public widely repeats Meta's inaccurate open source claims.
The custom license dictating Llama 2 includes several restrictive clauses that directly violate standard open source definitions. For example, companies with over 700 million monthly active users require special permission from Meta to use the model. Additionally, developers are strictly prohibited from using Llama 2 outputs to improve competing large language models.
The Open Source Initiative does not approve Meta's license, leading experts to warn that this misrepresentation creates a dangerous precedent. If major tech companies successfully label restrictive licenses as open source, it undermines the fundamental principle of non-discriminatory innovation. True open source requires unrestricted freedom to use and modify software, a standard that Llama 2 clearly fails to meet.
