Brave Search Jumps on the Large Language Model Bandwagon
Brave says that “Brave AI” uses multiple LLMs, retrained with data from their search index, but the ones they are using are open source (“The base LLM models are based on either BART or DeBERTa (which are open source and hosted on Hugging Face), with heavy retraining based on our own data from search results.”) and there is a blog post explaining in some detail about how this all works.
In summary, it appears that Brave has not only beaten Microsoft and Google to LLM integration, but has positioned it where it belongs, which is in a limited context as a complimentary feature, rather than to claim that a conversational chat bot is the future of search.
