LLMs, particularly the package 'transform' by Hugging Face, have seen a 50% increase in downloads in the last six months, now rivaling big deep learning packages like Keras, TensorFlow, and PyTorch. This surge indicates a shift towards open-source usage of LLMs in multi-part applications, with popular open-source packages like Lang chain, Haystack, and Llama Index experiencing doubled downloads in the same period.
