Rewrite and improve the following text: Large Language Model is an interesting field where the most advanced progression is happening in the industry rather than in the acedimia. For both commercial and safety reasons, most of the better models including GPT3.5/GPT4 are not open-sourced. However, there are a few open-sourced ones out there including Alpaca (https://crfm.stanford.edu/2023/03/13/alpaca.html) and Vicuna (https://vicuna.lmsys.org/), which are both fine-tuned version of the LLaMA released by Meta. Both these two models only takes a few hundred dollars to train, and will be able to run on a local (powerful) computer. 

Here below is a plot of the relative response quality of these models assessed by GPT-4. Note that both Alpaca and Vicuna has 'only' 13 billion parameters, where GPT-3.5 has 175 billion parameters and GPT-4 potentially more. Provide two versions of response separated with exactly 6 asterisk symbols: ******.
