Limitations of Large Language Models

Large language models (LLMs), while powerful, have common limitations that can affect their reliability and applicability. These include challenges in understanding context with high precision, generating factually accurate information in specialized domains, and handling tasks requiring real-time data or external knowledge. Additionally, bias in training data may lead to skewed outputs, and resource-intensive operations can limit accessibility for certain applications. These limitations are possibly more pronounced in models with smaller parameter sizes or those trained on less diverse datasets. It is important to recognize that these constraints vary depending on the model’s design, training data, and intended use case.

• Contextual understanding limitations
• Potential for biased or inaccurate outputs
• High computational resource requirements
