Yes, there are other large language models similar to ChatGPT that are available to the public. Some examples include:
GPT-2: This is a similar model to ChatGPT also developed by OpenAI. It has similar capabilities and is also available for use through the OpenAI API.
BERT: Developed by Google, BERT is a transformer-based model that is trained on a large corpus of text data and is capable of handling tasks such as natural language understanding and text classification.
RoBERTa: Developed by Facebook AI, RoBERTa is also a transformer-based model that is pre-trained on a large corpus of text data. RoBERTa is designed to improve on the performance of BERT on a wide range of natural language understanding tasks.
T5: A state-of-the-art language model developed by Google, that is pre-trained on a massive amount of text data and fine-tuned for a wide range of natural language understanding and generation tasks.
XLNet: Developed by Google, it's a transformer-based model that is trained on a large corpus of text data, similar to BERT and RoBERTa, but it is designed to overcome some of the limitations of the BERT model by using a more powerful training method.
These models are available either via APIs or can be downloaded and fine-tuned on specific tasks or datasets.
