Retrieval Augmented Generation (RAG) systems, which integrate external information sources to enhance LLMs' capabilities, struggle with the inherent ambiguity of human language, particularly sarcasm. This can lead to misinterpretations and inaccurate responses, hindering their reliability in real-world scenarios. The article explores this challenge and proposes a novel solution: Reading with Intent. It involves prompting LLMs to recognize emotional intent behind the text and incorporating binary tags that indicate whether a passage is sarcastic or not. Experiments demonstrate significant improvement in LLMs' performance in answering questions over sarcasm-laden text, across various LLM families. Future directions include enhancing sarcasm detection, exploring multi-class intent tags, and instruction-tuning for better understanding of emotionally charged language.

ChatGPT, powered by the Generative Pre-trained Transformer (GPT) language model, has sparked a revolution in AI applications. However, it lacks specialized knowledge and faces limitations around private data use. To overcome these challenges, organizations can fine-tune LLMs like GPT with their distinct workflows and proprietary or private data. Fine-tuning involves taking a pre-trained base LLM and further training it on a specialized dataset for a particular task or knowledge domain. This process includes setting up the development environment, choosing a model to fine-tune, preparing datasets, uploading training datasets, creating a fine-tuning job, checking the status of the model during fine-tuning, accessing the fine-tuned model, accessing model checkpoints, and improving the model. Fine-tuning can significantly enhance the efficacy of generative AI applications when applied correctly.
