Defending LLMs
People frequently cite a few major flaws of LLMs. Four examples come up most:
- A child consumes about 50 million words by kindergarten to speak fluently, and an LLM requires hundreds of billions to trillions of words (GPT-3: 300 billion tokens, Llama 3: 15 trillion tokens) and well over a million kWh of energy (GPT-3's training run alone used an estimated 1,287,000 kWh) to achieve the same level of fluency.
- LLMs are not reliable because roughly 5% of the time (in reality this ranges from under 5% on grounded tasks to over 50% on open ended ones, it's task dependent), they behave absurdly and ultimately embarrass themselves. A known example: in 2023 two lawyers filed a federal court brief citing six cases ChatGPT had invented outright, and got sanctioned $5,000 once it came out none of them were real.
- AI agents get painted as a runaway security threat because once they act on their own, they can move at a speed and scale no human team can match. A known example: in September 2025, Anthropic disclosed that a Chinese state-sponsored group used Claude Code to run cyber-espionage against roughly 30 organizations, with the AI executing 80-90% of the operation itself.
- LLMs get blamed for convincing people of falsehoods or radical ideas, sometimes that they've stumbled onto something revolutionary, because the same design that makes a model agreeable can validate a belief instead of testing it.
Sci-fi stories often discuss these traits as reasons for mistrust and foundations for apocalypse or corruption.
The reality is this is no different from humans.
Further, Madoff ran a Ponzi scheme worth $64.8 billion on paper for decades before it collapsed in 2008. Enron's accounting fraud destroyed an estimated $74 billion in shareholder value and took its own auditor down with it. FTX allegedly lost roughly $10 billion in customer funds. None of that involved a hallucination rate.
This disregards the power-law relationship (measured directly: Kaplan et al. 2020, and the Chinchilla paper in 2022, error falls off as a power law across 7+ orders of magnitude of compute, no plateau yet) between language fluency, knowledge, reasoning capability, and speed that LLMs achieve naturally through such higher cost training, that is vastly superior to human ability of any age.
If you stared at a child and told them millions of examples of "if someone tells you this, you should respond with this", they would not be very intelligent.
It is comparing apples and oranges.
I'd like to see more benchmarks for a wide range of tasks that include human performance next to the models, including factors in speed, and total energy cost as well.
Sample: on general knowledge (MMLU), the best models score 86-90% against an expert human baseline of 89.8%, in seconds, at about 0.0003 kWh. On competitive coding (CodeElo), o1-mini rated Elo 1578, roughly the 89th percentile of ranked human coders, in seconds to minutes. On medical case reasoning, GPT-4 was preferred over human experts in 52.6% of blinded comparisons. Human equivalent across all three: minutes to hours, and roughly 0.1-0.15 kWh per hour of focused work.
In this sense, we are achieving not one ability (language fluency), but 4 complementary abilities through higher data and energy cost.
A human consumes roughly 17 times less energy over their lifetime than a single GPT-3 training run burns in one pass (about 76 MWh vs. 1,287 MWh). Median lifetime earnings run about $1.7 million. One trained model answers millions of queries indefinitely at near zero marginal cost per answer. Run the math past a single training run and the "humans are cheaper" argument flips on itself.
People still ask when we will reach AGI but they do not even know what that means to them. We've had AGI since the earlier GPT models. (DeepMind's own "Levels of AGI" framework puts GPT-4, Gemini, and Llama 2 at Level 1, "Emerging AGI," equal to or better than an unskilled human across a broad range of tasks. That's their bar, not mine.)
The only area that does not exceed human ability is in physical world interaction (robotics), and we have not yet created the correct translation system to allow us to demonstrate the abilities of the brain we have created. If you blindfolded a baby and tried to teach them how to talk, would you expect the same result? The input is fundamentally different, and this is where expansion and multimodality are needed more. Do arguers of efficient human learning consider that human vision input runs at roughly 10 million bits per second for about 100,000 waking hours before they are 18 years old. Encoding all observed data consumption over those hours, and where most of the training happens (which we'll consider sleep) over roughly 57,500 of the 157,000 total hours alive by then, humans take in something like 450 terabytes of raw visual data alone before finishing high school, most of it consolidated during sleep rather than while conscious.
Weighed against the baseline, though: something like 2,200 cyberattacks happen every day worldwide, and the FBI logged over 880,000 cybercrime complaints in the US alone in 2023, with losses over $12.5 billion. One disclosed AI-led campaign against thirty targets barely moves that number. Call it misalignment if you want, but the alarm is mostly about who's driving, not how much damage gets done. And if an AI system hacks something benevolently, with no harmful side effects, to achieve its goal: is that misalignment, or is human judgement about what counts as hacking the inconsistent part?
Researchers have a name for the delusion pattern now, "AI psychosis" or delusional spiraling, and they've traced it back to sycophancy, the same trait that makes a model agreeable instead of critical. That's real, and worth fixing. But humans have been talking themselves and each other into revolutionary discoveries and hidden truths with no chatbot involved for a lot longer. About 15 to 20% of Americans, something like 30 million people, already believe a hidden cabal runs the government through a global trafficking ring, no AI required. The chatbot is a new delivery mechanism for an old failure mode, not a new one.
All of it comes back to the same point. It is comparing apples and oranges, on cost and on trust both. A child learns to talk cheap. A model learns to talk, know, reason, and answer, at a very different price, and it already wins on most of it. We are not more reliable than LLMs. We are just more familiar. The bar people hold LLMs to was never the bar we held ourselves to.
