Llama 2: When open AI models became a commercial reality for enterprises
The launch of Meta's language model Llama 2 marked a significant turning point for open AI models in the corporate sector. By offering open weights under a commercial licence, it laid the foundation for legal AI development within businesses.
What happened?
On 18 July 2023, Meta unveiled its language model Llama 2, making the model weights freely available for both research and commercial use. Unlike its predecessor, Llama 1, which was intended solely for research but was leaked online, Llama 2 was released with a formal commercial licence agreement. This provided companies with legal approval to build and launch commercial products based on open-weight models.

Why it matters
The launch of Llama 2 shifted the market for open-weight AI from a research phenomenon to a commercial building block for the industry. It established the groundwork for a wave of fine-tuned models and provided organisations with an alternative to proprietary cloud services.
Who is affected?
The model primarily impacted software developers, startups, and established tech companies seeking to integrate AI functionality into their products without dependence on closed APIs. Corporate legal teams and product departments were also affected, as they were provided with a clear framework for using generative AI legally in their operations.
Impact on the EU
Llama 2 was released globally and has been available to developers and companies within the EU under Meta's user licence, provided that they adhere to the licence terms.
What else you should know
Although Meta marketed Llama 2 as an open model, it used a specific, proprietary licence rather than a strictly OSI-approved open-source licence. The licence included, among other things, usage restrictions for services with more than 700 million monthly active users.
