• Characteristics Features:
  • Significant Performance: It is claimed to be the most sophisticated model with significant progress in terms of performance and AI capabilities. 
    • According to the company, the post-training processes have led to greatly improved capabilities like reasoning, code generation, and instruction following making Llama 3 more steerable.
    • Llama 3 can be used to create different forms of texts such as poems, code, scripts, and musical pieces. It can summarise factual topics and can also be used to translate languages.
  • Powering Conversation: The instruction-tuned version is meant for powering AI chatbots that are meant to hold conversations with users.
  • Open-source Ethos: It has also embraced an open-source ethos of releasing early and enabling the dev community (a community of software engineers) to get access to the models while they are still in development. 
    • According to Meta, it has built the best open-source models that are on par with the best proprietary models available today. 
  • Strengthen Interaction: All models of Llama 3 support context lengths of 8,000 tokens. This allows for more interactions, and complex input handling compared to Llama 2 or 1.
    • More tokens here mean more content input or prompts from users and more content as a response from the model. 
  • Safety & Security: Meta has said that it is dedicated to developing Llama 3 in a responsible way. It offers various resources to help others use it responsibly as well. 
    • This includes introducing new trust and safety tools with Llama Guard 2, Code Shield, and CyberSec Eval 2.
  • Integration: Meta said that it has integrated Llama 3 into Meta AI which can be used on Facebook, Instagram, WhatsApp, Messenger, and the web. 
    • It is readily available for developers as Meta has integrated the LLM into the Hugging Face ecosystem. 
    • It is also available via Perplexity Labs, Fireworks AI, and on cloud provider platforms such as Azure ML and Vertex AI.
