Prelims 2026 · Science and Technology · Question 42
Which of the following statements with regard to Large Language Models (LLMs) used in machine learning is/are correct ?
- LLMs assign probabilities to the next possible words and then pick the one with the highest probability.
- LLMs process data through mathematical optimization to minimise prediction errors.
- LLMs produce unbiased outputs.
Select the answer using the code given below :
Answer
1 and 2 only
2 is correct because LLMs are trained by mathematical optimization to reduce loss/prediction error. 3 is incorrect because LLMs can reflect biases present in training data. Statement 1 is accepted as broadly correct for a prelims-style question because LLMs assign probabilities over possible next tokens/words; in practice decoding may sample rather than always greedily pick the top token, but the core next-token probability idea is right. Hence, 1 and 2 only.
