When it comes to generative AI, the open source community has embraced Meta AI’s https://ai.facebook.com/blog/large-language-model-llama-meta-ai/ (Large Language Model Meta AI), which was released in February. However, when it was https://www.vice.com/en/article/xgwqgw/facebooks-powerful-large-language-model-leaks-online-4chan-llama in early March for anyone to download, it effectively became fully open source.
One of the tools developers can use to fine-tune LLaMA is LoRA (Low-Rank Adaptation of Large Language Models), which is available for free on https://github.com/microsoft/LoRA.
Also worth noting: Lightning AI has its own implementation of the LLaMA language model called https://github.com/Lightning-AI/lit-llama, which is available under the Apache 2.0 license.
LLaMA does seem like a great option for developers wanting more flexibility in using large language models.
