Introduction:

Llama, also known as Large Language Model Meta AI, represents a series of LLMs (Large Language Models).

Unveiled by Meta AI in February 2023.

The Large Language Model (LLM) Meta AI refers to a family of advanced language models developed by Meta AI.
These models are designed to understand and generate human-like text based on vast amounts of data they have been trained on.
LLMs are capable of various language-related tasks such as text generation, translation, summarization, and question answering.

Initially, Llama debuted in four variations: 7B, 13B, 33B, and 65 billion parameters.

Parameters indicate the size and complexity of an AI model, with higher numbers suggesting greater sophistication and capability.

What is Llama 3?

Meta has introduced Llama 3, the newest version of its LLM, boasting enhanced performance and AI capabilities.
The instruction-tuned version is specifically aimed at empowering AI chatbots for engaging in conversations with users.
It specialises in areas such as reasoning, code generation, and following instructions, rendering it more adaptable and versatile.
It is speculated that, it can generate diverse forms of text such as poems, code, scripts, and musical compositions.
Additionally, it may be capable of summarising factual topics and translating languages.

Meta has integrated Llama 3 into its Meta AI platform. This allows users to access it across various Meta-owned platforms such as Facebook, Instagram, WhatsApp, Messenger, and the web.
Developers can readily access Llama 3 through Meta’s integration with the Hugging Face ecosystem, a popular platform for AI model development and deployment.
It is also accessible via other platforms including Perplexity Labs, Fireworks AI, and major cloud provider platforms such as Azure ML and Vertex AI.
Meta plans to make Llama 3 models available on additional platforms in the near future, including AWS, Google Cloud, Hugging Face, Databricks, Kaggle and more.
Currently, Meta AI with Llama 3 is available in English across the US on WhatsApp.
It plans to expand to countries like Australia, Canada, Ghana, Jamaica, Malawi, New Zealand, Nigeria, Pakistan, Singapore, South Africa, Uganda, Zimbabwe, and Zambia.
