Large language models (LLMs) are facing scrutiny regarding their reasoning capabilities and tendency to produce hallucinations, instances where they generate incorrect or fabricated information. Andrej Karpathy, former Senior Director of AI at Tesla, suggests that these hallucinations are emergent cognitive effects arising from the LLM training pipeline. He explains that LLMs predict words based on patterns in their training data, rather than possessing factual knowledge like humans. This leads to situations where models generate plausible-sounding but entirely false information.

Researchers are actively working on improving the reasoning skills of LLMs while minimizing computational costs. One approach involves using distilled reasoners, which allow for faster and more efficient inference. Additionally, Alibaba has unveiled QwQ-32B, a 32 billion parameter AI model that rivals the performance of the much larger DeepSeek-R1. This model achieves comparable results with significantly fewer parameters through reinforcement learning, showcasing the potential for enhancing model performance beyond conventional pretraining and post-training methods.
