Model overview

The meta-llama-3.1-405b-instruct is Meta's flagship 405 billion parameter language model, fine-tuned for chat completions. It is part of a family of similar models from Meta, including the meta-llama-3-70b-instruct, meta-llama-3-8b-instruct, llama-2-7b-chat, llama-2-13b-chat, and llama-2-70b-chat models. These models span a range of parameter sizes and are tailored for different chat and completion tasks.

Model inputs and outputs

The meta-llama-3.1-405b-instruct model takes a variety of inputs, including:

Inputs

  • Prompt: The text prompt to generate completions for
  • System Prompt: A system prompt that helps guide the model's behavior
  • Top K: The number of highest probability tokens to consider for generating the output
  • Top P: A probability threshold for generating the output
  • Min Tokens: The minimum number of tokens the model should generate as output
  • Max Tokens: The maximum number of tokens the model should generate as output
  • Temperature: The value used to modulate the next token probabilities
  • Presence Penalty: Presence penalty
  • Frequency Penalty: Frequency penalty
  • Stop Sequences: A comma-separated list of sequences to stop generation at

The model outputs an array of generated text.
