Llama 3.1

Llama 3.1 is a large language model developed by Meta, released in July 2024. It represents an incremental update to the Llama 3 model family, building upon the previous generation’s architecture and training methodology. The model is available in three parameter sizes: 8 billion (8B), 70 billion (70B), and 405 billion (405B) parameters, enabling deployment across different computational constraints and use cases.

Scale and Positioning

The 405B variant marks Meta’s entry into the frontier class of large language models, placing it alongside other state-of-the-art systems in terms of model scale and intended capability. This larger variant represents a significant increase in model size compared to the 70B predecessor in the Llama 3 line, reflecting ongoing industry trends toward larger model parameters.

Training and Capabilities

Llama 3.1 was trained using an extended context window relative to earlier versions, allowing it to process longer input sequences. The model is made available under Meta’s standard licensing terms, which permit both research and commercial use subject to the company’s acceptable use policy. Like other models in the Llama family, Llama 3.1 is designed to function as a general-purpose instruction-following language model suitable for a range of natural language processing applications.
