Meta have released LLaMA, an LLM comprising 4 foundation models with 7B to 65B parameters, claiming that it outperforms many benchmark models on various tasks. In particular, LLaMA-13B outperforms GPT-3 (175B) on most benchmarks, and LLaMA-65B is competitive with the best models, Chinchilla70B and PaLM-540B.

LLaMA isn’t like ChatGPT or Bing; it’s not a system that anyone can talk to. Rather, it’s a research tool that Meta says it’s sharing in the hope of “democratizing access in this important, fast-changing field.” In other words: to help experts tease out the problems of AI language models, from bias and toxicity to their tendency to simply make up information.
