Meta’s Meta AI chatbot is built on top of the LLaMA 3 large language model, as IEEE Spectrum reports:

Open-source developers have embraced Llama 3 with similar speed. Llama 3 8B tops the list of trending models on the AI developer hub Hugging Face, with over 275,000 downloads in its first five days. That far outpaces other recent releases: Mistral AI’s Mixtral-8x22B, which achieved benchmark scores only a hair behind Llama 3 70B, was downloaded fewer than 100,000 times in its first month.

Meta has drawn criticism over its approach to “open” AI. The license attached to Llama 3 doesn’t conform to any accepted open-source license, and some aspects of the model, such as the training data used, are not revealed in detail. Yet that criticism hasn’t halted Meta’s ascent and, with Llama 3, the company has entrenched its lead over competitors.
