Question
Which of these are NOT the limitations of Large Language Models like OpenAI GPT?
A. They can perform wide variety of NLP tasks by learning from examples and not requiring explicit programming for each task.
B. There is currently no single source of Truth.
C. They give plausible-sounding but incorrect or nonsensical answers.
D. They lack real world experiences and emotions.
Answer
A. They can perform wide variety of NLP tasks by learning from examples and not requiring explicit programming for each task.
Explanation
Large language models (LLMs) like OpenAI’s GPT series have some remarkable capabilities, but also significant limitations. The correct answer is that option A is NOT a limitation of LLMs – it actually describes one of their key strengths.
LLMs like GPT are capable of performing a wide variety of natural language processing tasks, such as question answering, text generation, translation, summarization, and more. Importantly, they can learn to do these tasks from examples alone, without requiring explicit programming for each specific task. This is enabled by their ability to learn general language understanding and generation capabilities from ingesting and training on huge volumes of natural language data.
However, LLMs do have some notable limitations:
- Lack of a single source of truth (option B): LLMs learn from unstructured web data that can contain inaccuracies, biases, and contradictions. They don’t have a single coherent knowledge base.
- Plausible but incorrect outputs (option C): While LLMs often generate fluent and plausible-sounding text, they can also produce statements that are factually incorrect, illogical, or nonsensical. They lack robust mechanisms for validating the accuracy of their outputs.
- Lack of grounding in real-world experience (option D): LLMs learn about the world purely through natural language text, not through embodied real-world experiences, perceptions and interactions like humans have. This lack of grounding limits their understanding.
So in summary, the key strength of LLMs is their ability to perform many language tasks by learning from examples (option A), while their limitations include lack of a truth source, outputs that can be incorrect, and lack of real-world grounding (options B, C, D). Developing techniques to mitigate these limitations while leveraging the impressive few-shot learning capabilities of LLMs is an active area of research in the field of AI.
