A commercial version of Llama 2, an open-source large language model (LLM) that use artificial intelligence (AI) to produce text, graphics, and code, has been made available by Meta, more commonly known to us as Facebook.

Under a research licence, the initial version of Llama was accessible to academics and researchers. However,Llama’s model weights were exposed, sparking some controversy and prompting a government investigation. With Llama 2, Meta is putting the past disagreement behind it and advancing with a more potent model that will be more widely applicable than its predecessor and may completely change the LLM landscape.

Nevertheless, is Llama 2 truly open source? Although Meta makes the right points, the Open Source Initiative (OSI), the leading authority on open-source licensing, has not given its approval to the Llama 2 Community Licence Agreement.

What lies within LLaMA?
A transformer-based auto-regressive model of language is called LLaMA. In February, Meta officially described the initial version of Llama as a 65 billion-parameter model capable of performing a wide range of typical generative AI tasks.

Llama 2 has a variety of model sizes, spanning seven, thirteen, and seventy billion parameters. The pre-trained models, according to Meta, were developed using a sizable dataset that was 40% bigger than the one used for Llama 1. Additionally, the context length has been doubled from Llama 1 to two trillion tokens.

Promoted safety measures in Llama 2 by Meta
In Llama 2, safety is just as important as power. First, Llama 2 is pre trained using data that is readily accessible. After then, the model goes through a number of SFT steps (supervised fine-tuning). Then, to provide yet another layer of safety and accountability, Llama 2 gains from a cycle of learning through reinforcement from human feedback (RLHF).

In-depth information on the extensive measures used to help provide safety and prevent potential bias is provided in Meta’s research report on Llama 2.
