Limitations of Large Language Models: Common Challenges

While large language models (LLMs) have achieved remarkable capabilities, they still face common limitations that can impact their reliability and applicability. These models may struggle with data bias, hallucinations (generating incorrect or fabricated information), and computational inefficiency, particularly with very large parameter sizes. They also rely heavily on the quality and representativeness of their training data, which can lead to ethical concerns or misinterpretations in sensitive contexts. Additionally, LLMs may lack true understanding of complex or domain-specific tasks, requiring careful validation. These limitations highlight the importance of ongoing research and responsible deployment.

Shortlist of limitations:
- Data bias and representation issues
- Hallucinations and factual inaccuracies
- High computational resource demands
- Ethical and safety risks in sensitive applications
