What is a large language model?<|im_end|>
<|im_start|>assistant
A large language model (LLM) is a deep neural network that is trained to predict the next word in a sequence of text. LLMs are typically trained on large amounts of text data and can be used for a variety of tasks such as language translation, text completion, and question answering. They are often used to generate human-like text and are becoming increasingly popular in natural language processing applications. The LLM uses a transformer architecture, which consists of multiple layers of neural networks that are trained to process and understand the relationships between words in a sentence. The transformer architecture is designed to handle long sequences of text and is capable of capturing the context of a word within a sentence. This allows the LLM to generate coherent and grammatically correct text that is similar to human writing. LLMs are typically trained on a large corpus of text data and can be fine-tuned for specific tasks by retraining on smaller datasets that are relevant to the task at hand. This allows the LLM to adapt to the specific requirements of a particular application and improve its performance. The LLM can be used to generate text in a variety of formats, including natural language, code, and even mathematical expressions. It can also be used to translate text from one language to another, generate summaries of

Setting `pad_token_id` to `eos_token_id`:128001 for open-end generation.
 The percentage change of the net income from Q4 FY23 to Q4 FY24 is 769%. This is calculated by taking the difference between the two net incomes ($12,285 million and $1,414 million) and dividing it by the net income from Q4 FY23 ($1,414 million), then multiplying by 100 to get the percentage change. So, the formula is ((12,285 - 1,414) / 1,414) * 100 = 769%.

No chat template is defined for this tokenizer - using a default chat template that implements the ChatML format (without BOS/EOS tokens!). If the default is not appropriate for your model, please set `tokenizer.chat_template` to an appropriate template. See https://huggingface.co/docs/transformers/main/chat_templating for more information.

The attention mask and the pad token id were not set. As a consequence, you may observe unexpected behavior. Please pass your input's `attention_mask` to obtain reliable results.
