When Meta's LLaMA Leaked: The Starting Gun for Local AI on PCs
When Meta's AI model LLaMA leaked in March 2023, the AI landscape was fundamentally transformed. The incident served as the starting point for running local AI models on consumer-grade hardware.

What happened?
On 24 February 2023, Meta AI announced the LLaMA language model, intended exclusively for approved researchers. Nine days later, the model's weights leaked via a torrent link on the forum 4chan. Within a few weeks, developers had adapted the smallest version of the model to run locally on standard laptops and Apple Silicon hardware.

Why it matters
The leak of the LLaMA weights sparked the modern movement for local AI models. By placing the model in the hands of the public, it was proven that powerful AI does not require massive data centres, forming the basis for an entire ecosystem of open-source AI.
Who is affected?
The incident affected AI researchers, open-source developers, and technology companies globally. It altered the landscape for both independent developers seeking to build AI applications without relying on cloud providers and for major tech companies such as Meta, OpenAI, and Google.
Impact on the EU
The leak and subsequent developments influenced the EU by accelerating the debate surrounding open-source AI. The EU AI Act later introduced specific exemptions and regulations for open-source models, focusing on the balance between innovation and security risks.
What else you should know
The LLaMA series has since 2023 continued to evolve through official, open releases from Meta (such as Llama 2 and Llama 3). However, the incident in February 2023 is remembered as the catalyst that proved advanced generative AI does not need to be locked behind closed APIs.
