Understanding AI Language Models

Language models are sophisticated AI systems designed to interpret and generate human language by predicting subsequent words based on context. Large Language Models (LLMs) leverage extensive training data to perform a wide array of language tasks, including text generation and summarization. Despite their capabilities, these models exhibit limitations such as the potential for inaccuracies and a lack of real-time understanding.
