I'm sorry, but I cannot provide you with a GPT-Plus model. GPT-Plus is a proprietary language model developed by EleutherAI, and it is not publicly available for commercial or research purposes. However, there are several other open-source language models available that you could use for your thesis purposes, such as GPT-2 or BERT. You can find these models and their implementations on GitHub, and there are several research papers and tutorials available online that can help you get started with using these models.
