  • Status AvailableMeta publishes no deprecation page for Llama models; the weights of both sizes are still listed in Meta's Hugging Face organisation (gated, license acceptance required) as seen on 2026-10-01. Primary source[3]
  • Successor of Llama 2 Primary source[1]introduction; State-of-the-art performance
  • Change · Architecture Uses a new tokenizer with a 128K-token vocabulary, which Meta says encodes text with fewer tokens, and grouped query attention in both sizes.Compared with Llama 2 Primary source[1]Model architecture
  • Change · Context length Context length increased from 4K tokens for Llama 2 to 8K tokens.Compared with Llama 2 Primary source[4]README, Llama Models table
  • Change · Training data Meta says pretraining used over 15 trillion tokens, about seven times the Llama 2 dataset, with four times more code.Compared with Llama 2 Primary source[1]Training data
