What is Llama-3?

Llama-3, Meta's newest addition to its series of large language models (LLMs), marks a substantial advancement in natural language processing (NLP) technology.
This new iteration improves upon the achievements of previous versions by offering responses that are not only more efficient but also more attuned to the context, even when dealing with queries that are sensitive or controversial.

How does Llama-3 work?

Llama-3 utilizes a Transformer-based design to focus on its computation, advanced vocabulary encoding, and attention mechanisms.

Its training method involves lengthy text inputs while being mindful of document boundaries to avoid data leakage.

Here are some of its characteristics:

• Included a standard decoder-only Transformer architecture.
• Has a 128K token vocabulary for improved encoding efficiency.
• It has grouped query attention (GQA) to enhance inference speed.
• Accepts longer inputs of up to 8192 tokens of input text.
• Use of masks during self-attention to maintain clear distinctions across document boundaries.

Applications of Llama-3

What Llama-3 is useful for:

• Assistance in Dialogue: Llama-3 provides support in tackling challenges, proving itself as a helpful tool for ideation and creative thinking sessions.

• Analysis of Text: It can classify text, delivers answers to straightforward questions, and identifies specific details within documents or programming environments.
• Support for Programming: Demonstrating abilities in coding, Llama-3 aids in the creation of code fragments, offers help with troubleshooting issues, and elucidates upon existing programming.
• Generation of Creative Content: Leveraging its capacity to generate content, Llama 3 is capable of generating creative texts such as poetry, narratives, or large texts from given ideas.
• Logical Thinking and Condensation: Logical examination of tasks like evaluating discussions or addressing complex questions, Llama 3 can perform distilling of extensive texts down to their essential elements.

Advancements of Llama-3

Meta's Llama-3, is a major upgrade from LLaMA-2, with wider availability and integration and overall superior performance across the board

Llama-3 overall shows significant improvements in key performance metrics like MMLU, ARC, and DROP compared to LLaMA-2, indicating better knowledge, skill training, and reasoning abilities.

With 15 trillion tokens covering a diverse range of languages, this makes Llama-3 a versatile tool for various tasks in different languages. 

Llama-3 access and availability

As for now, Llama-3 offers two versions of model weights: pre-trained weights more suitable for additional tuning for a specific task and instruction-tuned version for usage out of the box. For both versions, checkpoints are available in two sizes: 70B and 8B parameters. While we are writing this, Meta is training the biggest version of Llama-3, an enormous 405B model.

If you want to quickly try Llama-3 without hosting it yourself, you can access Llama-3 API on different cloud platforms, such as Azure, AWS.
