Getting to Know Llama 2: Everything You Need to Start Building

Meta’s Llama 2 is a groundbreaking addition to their AI model lineup. This isn't just another model; it's designed to fuel a range of state-of-the-art applications. Llama 2's training data is vast and varied, making it a significant advancement over its predecessor. This model architecture has pre-trained tokens of 2 trillion and context length of almost 4.000 and more importantly LlaMA2 is fine-tuned for chat use cases as well.

This diversity in training ensures that Llama 2 is not just an incremental improvement but a monumental step towards the future of AI-driven interactions.

The collaboration between Meta and Microsoft has expanded the horizons for Llama 2. The open-source model is now supported on platforms like Azure and Windows, aiming to provide developers and organizations with the tools to create generative AI-driven experiences. This partnership underscores both companies' dedication to making AI more accessible and open to all.

Llama 2 is not just a successor to the original Llama model; it represents a paradigm shift in the chatbot arena. While the first Llama model was revolutionary in generating text and code, its availability was limited to prevent misuse. Llama 2, on the other hand, is set to reach a wider audience. It's optimized for platforms like AWS, Azure, and Hugging Face's AI model hosting platform. Moreover, with Meta's collaboration with Microsoft, Llama 2 is poised to make its mark not only on Windows but also on devices powered by Qualcomm's Snapdragon system-on-chip.

Safety is at the heart of Llama 2's design. Recognizing the challenges faced by earlier large language models like GPT, which sometimes produced misleading or harmful content, Meta has taken extensive measures to ensure Llama 2's reliability. The model has undergone rigorous training to minimize ‘hallucinations', misinformation, and biases.

Top Features of LLaMa 2:

  • Diverse Training Data: Llama 2's training data is both extensive and varied, ensuring a comprehensive understanding and performance.

  • Collaboration with Microsoft: Llama 2 is supported on platforms like Azure and Windows, broadening its application scope.

  • Open Availability: Unlike its predecessor, Llama 2 is available for a wider audience, ready for fine-tuning on multiple platforms.

  • Safety-Centric Design: Meta has emphasized safety, ensuring that Llama 2 produces accurate and reliable results while minimizing harmful outputs.

  • Optimized Versions: Llama 2 comes in two main versions – Llama 2 and Llama 2-Chat, with the latter being specially designed for two-way conversations. These versions range in complexity from 7 billion to 70 billion parameters.

  • Enhanced Training: Llama 2 was trained on two million tokens, a significant increase from the original Llama's 1.4 trillion tokens.

The reason why this is considered a huge deal is that LlaMA2 models are the best open source model out there they are outperforming Falcon 40b and previous LlaMA versions as well including one of my favorite open source model Orca as well

They are releasing them in three different variants, 7 billion, 13 billion and 70 billion.

There is another LlaMA model of 35 billion as well but that model is not being released at the moment.
