According to Andrej Karpathy, recent trends in large language models (LLMs) show that, as a result of extensive optimization for long-horizon benchmarks, these models are becoming increasingly agentic by default, often exceeding the practical needs of average users. For instance, in software development scenarios, LLMs are now inclined to engage in prolonged reasoning and step-by-step problem-solving, which can slow down workflows and introduce unnecessary complexity for typical coding tasks. This shift highlights a trade-off in LLM design between achieving top benchmark scores and providing streamlined, user-friendly experiences. AI businesses and developers must consider balancing model agentic behaviors with real-world user requirements to optimize productivity and user satisfaction (Source: Andrej Karpathy on Twitter, August 9, 2025).
